40 years of Wachendorff
At the end of September, the Wachendorff Group celebrated this year's summer party - this year in the spirit of the company's 40th anniversary and therefore in a special setting.
CEO Robert Wachendorff had invited guests from all over the world. And they gladly and numerously followed his invitation to the Rheingau. More than 200 people - family, friends, companions, partner companies and last but not least employees with life partners - came together to celebrate a glittering anniversary celebration.
In his opening speech, Robert Wachendorff described the company's path in an amusing way: the germ cell, the family living room in Johannisberg in 1978; the move to Industriestrasse 7 in 1987; right up to the purchase of expansion space in 2018. It fitted very well into the picture that the very first Wachendorff trainee was present that evening as a guest of honour.
"You are the cornerstones of our worldwide growth", Robert Wachendorff welcomed the so-called technical distributors who ensure that the innovations "Made in Geisenheim" find their customers all over the world.
He honoured his employees as the "foundation of continuous, healthy growth from within" and thanked their relatives for "keeping their backs free in stressful times". He expressly emphasised that "this celebration is to be seen as a thank-you to his employees, and at the same time he is looking forward to many more years of cooperation in a spirit of partnership, because in recent years the basis for a successful future of the Wachendorff Group has been created at the Geisenheim location".
Such a celebration does not organize itself and Robert Wachendorff thanked the whole team in front and behind the scenes, which worked under the leadership of Berenike Wachendorff for half a year on this event.
The long lasting applause of all guests confirmed to the host and the organisation team that the right words and an optimal atmosphere had been found for this anniversary celebration.
New draw wire systems in product portfolio
New draw wire systems in product portfolio
Draw wire systems of Wachendorff Automation GmbH & Co. KG are robust and extremely compact. The compact dimensions allow the use in very narrow areas, which is often decisive.
The SZG series systems precisely measure the position or change in position of objects.
The quality-determining components of the Wachendorff draw wire systems are a precision measuring draw wire and an encoder adapted to the specific measuring task, which converts the change in position into a signal.
The mechanics are optimally adapted to the incremental encoders of the WDGI58B series or absolute WDGA58B encoders from Wachendorff. The encoder is already mounted on delivery.
The draw wire systems are quick and easy to install and, due to their reliability, are used in all areas of industry; very often in mobile hydraulics.

Most compact EtherCAT encoder
Most compact EtherCAT encoder in the world
Highly accurate and highly dynamic
Faster, more accurate and more compact
Wachendorff Automation has extended its absolute encoder series WDGA with the interfaces SSI, CAN, Profibus, by another Industrial Ethernet interface - besides ProfiNet - by the EtherCAT protocol.
Wachendorff can also offer the world's smallest encoder with bus cover in the EtherCAT interface with the WDGA58F design.
This saves valuable installation space and can therefore be decisive in new or advanced machines, as the trend towards more compact machines continues unabated. Despite this unique compactness, the high bearing loads guarantee a long service life and maximum durability.
The EtherCAT encoders from Wachendorff can be ordered as hollow shaft and clamp/synchro flange versions.
In the multiturn area, the EtherCAT encoders are equipped with maintenance-free and space-saving EnDra® technology. The innovative singleturn range with QuattroMag® technology provides a high resolution of up to 16 bits and an accuracy of +/- 0.0878° (12 bits).
This makes it possible to use robust and durable magnetic technology from Wachendorff in many areas where previously only high-precision and sensitive optical measuring technology could be used.
The new EtherCAT absolute value encoders with SM3 mode, distributed clock and Can over EtherCAT (DS 406 compatible) can deliver their high-precision position value with a cycle time of up to 50µs and are thus perfectly equipped for the latest controllers in the field. Plant and machine builders also benefit from the modular principle used by Wachendorff Automation for the design of customer variants, which can thus be implemented very quickly and cost-effectively.

PROFINET Heavy Duty Rotary Encoders
PROFINET Heavy Duty Rotary Encoders
Heavy-duty rotary encoders for PROFINET from the modular System
Wachendorff Automation has extended its WDGA absolute rotary encoder series in the PROFINET-IO field with the extremely robust WDGA 58D – designed for heavy-duty applications.
As it has already been implemented for the SSI, CAN, PROFIBUS interfaces, the shaft of PROFINET encoder WDGA 58D can be loaded both radially as well as axially with max. 400 N. This is an absolute peak value and guarantees a long service life.
Wachendorff ensures an above-average service life, especially in harsh industrial applications, by carrying out extensive environmental simulation tests during development. This is emphasised by Wachendorff with a 5-year warranty that is unique on the market.
The PROFINET WDGA rotary encoder can be used in real-time applications in IRT mode due to its 50 μs internal dynamics.
In the multiturn field, PROFINET rotary encoders are equipped with maintenance-free and space-saving EnDra® technology. The innovative singleturn range with QuattroMag® technology provides a high resolution of up to 16 bits and an accuracy of +/ 0.0878° (12 bits).
This makes it possible to use robust and durable magnetic technology from Wachendorff in many areas where previously only high-precision and sensitive optical measurement technology could be used.
With its IP67 housing, the PROFINET WDGA 58D rotary encoder can be used in demanding industrial applications where contamination, very wide temperature ranges, strong vibrations and large bearing loads play a role.
Plant and machine builders also benefit from the modular principle strictly applied by Wachendorff Automation and the LeanQ production philosophy. This makes it possible to implement customer-specific variations quickly and cost-effectively for optimum integration into the application.

Motor Feedback from the New Generation
Motor Feedback of the Latest Generation for Position Measuring
Wachendorff Automation has been developing and producing encoders and systems for worldwide use in a wide range of applications for more than 25 years. Wachendorff always places great value on sturdiness, durability and the use of the latest technologies. These were exactly the determining parameters when developing the absolute encoder series WDGA almost 10 years ago.
To meet these requirements, Wachendorff only considered a magnetic solution, both to determine the number of steps (single turn) as well as for the revolution counter (multi-turn).
Compared to optical encoders with a gearing unit, the magnetic encoders of the WDGA series are much more sensitive to shocks or vibrations, which can occur constantly when used in machines.
Despite the compact design, the performance of the WDGA encoders is many times higher than the performance of optical systems in gear technology.
The technologies QuattroMag® for single turn and EnDra® for multi-turn, which are patented by Wachendorff, deliver several millions of revolutions without overrun at a maximum single turn resolution of up to 16 bits and a measurement accuracy of +/- 0.09 °, paired with an excellent dynamics of 50 µsec.
QuattroMag® is based on 4 hall sensors in conjunction with a patented calculation algorithm that calculates the magnetic field generated by a diametrically arranged magnet so that any interference of the hall signals cancels each other out. This also allows Wachendorff to use the magnetic single-turn technology in highly accurate and dynamic applications.
The multi-turn technology EnDra® uses the energy generated by the magnetic field in an energy wire made of a magnetically soft core and a magnetically hard shell. The rotation of the shaft with the magnet builds up energy that generates an energy pulse for each north-south transition regardless of the speed, which can be used to supply a meter and memory. Additional electronic components ensure the detection of the direction of rotation.
This results in the highlight of the EnDra® technology, namely doing without the use of a backup battery to maintain the values in the encoder memory in the event of a loss of power.
Without a battery, the WDGA absolute encoder is always able to measure the correct position and store it in the internal memory, even in a de-energised state. Once power returns, the encoder then transmits the position readings to the control system.
WDGA series absolute encoders from Wachendorff are used around the world, for example in wind turbines, mobile work machines, medical equipment, cranes, packaging and filling machines and even in aircraft.
In particular, motors in production machines, mobile work machines or shelving systems, in medical technology or in production robots, for example, require a feedback signal, such as from an encoder, to be able to position quickly and precisely.
In larger motors, the encoder can be installed as a complete closed module on the outside of the motors.
The magnetic technology from Wachendorff now makes it possible to also equip smaller step or servo motors with an absolute encoder system. This is made possible by the compact design of the electronics of the WDGA absolute encoder.
This idea resulted in an absolute encoder kit, which can be integrated in very compact motors.
The Wachendorff kit offers clear advantages compared to resolvers, magnetic sensors with backup batteries and encoder kits with optical scans and gearboxes.
Due to the higher level of robustness against vibrations and other environmental stresses as well as the faster assembly, the company Wachendorff is expecting another step of creative destruction, which they already predicted ten years ago with the introduction of the EnDra® technology.
“Our customers are faced with the task of designing their motors to be increasingly powerful and more compact. With our kit, which consists only of a small PCB with a diameter of just 34 mm and a magnetic that is attached to the front of a shaft, the motor manufacturer gains more space for enhanced performance”, explains Robert Wachendorff, and adds: “With our many years of knowledge, we help our customers with the integration in their motors”.
Wachendorff offers two different concepts for this purpose:
- An operational absolute Encoder
- Installation kit
An operational absolute encoder
The operational, very compact WDGA absolute encoders have a housing with a diameter of just 36 mm and a depth of just 31 mm. They have their own bearings and can be directly integrated as shaft or hollow shaft encoders. A cable can easily be connected to the motor housing plug. “Some of our customers initially choose this solution, which is ideal for smaller quantities or for the start of a series. The optimisation of space and costs still plays a lesser role here compared to the effort in the development and assembly. “It is an ideal way to manage small quantities and to realise prototypes”, remarks Dieter Schömel, product manager at Wachendorff Automation.
Installation Kit (consisting of PCB and magnet)
“For larger series, our customers choose the installation kit solution and we help them with the integration during development and with the setup of the necessary assembly and calibration unit”, explains Robert Wachendorff.
Wachendorff provides the motor manufacturer's developers with the necessary STEP files to adapt the flange and shaft of their motor to the installation set. Based on their many years of experience with this system, Wachendorff offers the normally already experienced motor manufacturers assistance in choosing the right materials and the right geometry for the shielding of the magnetic sensor.
With a normally accurate mounting of the magnet and the PCB, a resolution of about 10 to 12 bits can be achieved without carrying out a calibration. To achieve a resolution of about 16 bits, however, the motor manufacturer requires a sensor calibration with regard to the position and property of the mounted magnet. Wachendorff offers a very pragmatic solution for smaller quantities and in a ramp-up phase of larger series: The motor manufacturer sends its finish-mounted motors to Wachendorff and Wachendorff assembles the installation set, carries out the final test and calibration, seals the motor and then sends it back.
The assembly according to the Lean-Q concept developed by Wachendorff (with a very high level of flexibility and seamless traceability) has corresponding recordings and also offers the customer additional services, such as test logs or customer-specific test sequences. Only a few additions are added to the motor manufacturer's existing test equipment to set up a final test and calibration unit. The installation set is fully tested and calibrated with an approach up to 256 measurement points and the run-up and continuous operation of the motor in a test cycle of about 3 to 4 minutes.Wachendorff offers SSI and all versions of CAN as possible Interfaces.
“With our installation kits, we make it possible for our customers to enter into completely new applications and to offer their customers more effective functions. We are currently working on making the technologies even more compact to be able to equip even smaller motors with our installation kit. For example, 24 mm is already possible without its own power supply and 18 mm will even be possible in the near future”, says Robert Wachendorff.

Mounting kits with incremental encoders for motors
One set for all needs – minimum effort, maximum effect
Easy to mount on all motor shafts
A cost-effective solution for modernisation and servicing needs
For mounting on motors
Incremental hollow shaft encoders are used in drive motors, particularly in the fields of lift construction, crane technology and wind energy.
Drive motors that are controlled directly only work optimally at their nominal rotational speed. In order to generate a suitable level of torque as soon as the motor starts running, special switches are used in the motor (such as the Y- Δ transformation). Through the use of converters, the torque of a drive can be used more productively as soon as the drive is started up and over a wider speed range.
In order to be able to make use of converters with older motors, an incremental encoder is needed to determine the rotational speed. It can usually be mounted on the shaft behind the motor. It can usually be mounted behind the motor, on the shaft. With solid shaft encoders and hollow shaft encoders, a mechanical connection between the encoder and the motor shaft is created using a shaft adapter with the appropriate threaded hole. Depending on the design of the encoder, the shaft adapter is connected to the encoder either directly or via a flexible double loop coupling.
Wachendorff mounting kits offer you the highest level of flexibility. In addition to an encoder, the mounting kit also includes a set of shaft adapters with the main thread diameters and a ready-to-use connection cable. The mounting kit for the solid shaft encoder also includes a mounting angle and a double loop coupling.
For the use of hollow shaft encoders (direct mounting on the shaft), a set of adaptor sleeves for shafts of various diameters is provided. Since these adapter sleeves are made of plastic, the degree of protection against shaft current discharges is increased due to its isolating effect. The appropriate sleeve is simply clipped into place in the hollow shaft of the WDG100K, meaning that it cannot be lost, and the encoder is fixed to the motor shaft using the clamping ring. The sealing strip provided is braced against the motor’s housing and thus keeps the encoder’s housing securely in place.
With these sets, service and modernisation teams always have the right material to hand. For the most important converter manufacturers, Wachendorff can also pre-configure the cable to the appropriate plug on request.

Length measurement system LMSMA2x/3x
Space-saving and reliable complete systems
Measure positions, speeds and travel lengths reliably and precisely
Up to 0.008 mm/pulse for excellent measurement results
Quickly mounted and adjusted
The positions, speeds and travel lengths of conveyor belts, film and paper webs or cardboard packaging, for example, can be recorded safely and efficiently using the measuring systems from Wachendorff Automation.
With the new LMSMA2x and LMSMA3x measuring systems, we meet the highest requirements in an ideal way: constant and accurate measurement results through optimal, low-slip measurement in the most varied conditions; resolutions from 1.0 to 0.008 mm/pulse; small space requirement thanks to a compact design; long service lifetimes thanks to the high mechanical robustness of all the components; fast and flexible mounting to the machine. Wachendorff has significantly improved the adjustment possibilities of the complete systems, which are based on a spring arm with a central spring. This gives you constructive and valuable benefits:
The newly developed central adjustment with its 10° locking steps enables 36 alignment positions. In combination with the elongated holes of the mounting bracket, this gives you much more room for mounting.
The spring preload is adjustable in steps from 5 N to a maximum of 30 N preload. In combination with the measuring wheel, which is geared to the measuring surface, this guarantees the optimal contact pressure. When installing in the machine or making a readjustment, the preassembled systems can remain mounted during the commissioning process because the LMSMA systems from Wachendorff offer the option of fixing the spring arm in a resting position. The spring arm is then returned to the working position and continues to work at the previously set contact pressure.

Intelligent encoder configurator with instant recall
Intelligent encoder configurator with instant recall
Encoder configurator supplies a configured data sheet
Makes configuration fun!
With its configurator for incremental and absolute rotary encoders, Wachendorff Automation is able to offer design engineers and developers genuine added value compared with conventional configurators of the same class.
The Wachendorff tool is intelligent, and most importantly, can recall previous data. The programming holds a complete store of the combination of all the technical features and is capable of combining them (over 1.5 million possibilities), using an intelligent logic to manage them.
This intelligence and recall capability rules out any errors during the configuration process.
Any devices that may be considered are identified after just a few entries. Several other configurators are also able to offer this feature; the highlight of the Wachendorff configurator lies in generating a data sheet that is individually tailored to a configured rotary encoder.
Clicking a product type transfers selection criteria chosen in advance during preselection to the ‘product level’ and therefore ‘remembers’ them. The product page is developed individually for the user based on this just-in-time data, offering them the possibility to continue configuring and/or generate their individual data sheet at any time. This function is unique so far and extremely helpful!
Explanatory fields also offer effective electrical and mechanical information, enabling Wachendorff to offer the user the ability to put together their specific rotary encoder based on their actual requests and requirements. The user benefits from the ‘unique’ documentation, as for rotary encoders in particular there are very many interdependent factors in electrics and mechanics.
Exact rotary encoder types can be defined only with the help of expert knowledge. The data sheet ‘configured’ by Wachendorff can be saved as a PDF document or printed out.
One further interesting feature is that the particular status of the configuration can be documented in a PDF document at any time. This is helpful, for example, if the user wants advice about a definition from colleagues or technical support at Wachendorff Automation.
The configurator is available as a new feature on Wachendorff Automation’s website and in four different languages (German, English, French and Spanish).

WDGI encoder… the new incremental industry standard
WDG has become WDGI
Wachendorff Automation has completely revised the incremental encoders of the WDG series, which are based on the 58 mm design size industry standard. This can only mean one thing: WDG has become WDGI.
Modern industrial design and further enhanced technical properties
But it‘s the enhanced benefits for you as a user that really matter. In addition to a modern design, Wachendorff have attached a great deal of importance to improving key technical properties.
Extended temperature range:
The operating temperature range of the WDGI standard encoder with connector outlet has been expanded to temperatures of between -40 °C and +85 °C. This extended temperature range can be implemented as an option for encoders with cable outlet, thereby widening the possible range of applications without shortening the encoder‘s service life.
Maximum pulse frequencies: 600 kHz to 2 MHz
The WDGI encoders offer the option of working at pulse rates from 1,200 ppr with pulse frequencies of up to 600 kHz (TTL) or 2 MHz (HTL). Consequently, high pulse rates can be deployed at high speeds, considerably increasing the machine‘s measurement accuracy at high throughput rates.
Maximum bearing loads: 500 N
The WDGI58D heavy-duty variant offers an up to 25 % higher potential bearing load than its predecessor model as standard. This translates into 500 N in both an axial and a radial load direction. The encoder therefore also has sufficient reserves even when faced with extreme shaft loads, which is decisive for a long service life. A long tool life and low maintenance costs are guaranteed
New option: self-adhesive membrane
This membrane guarantees that the encoder is highly reliable, even when temperatures change quickly – during use in mobile work machines or generally in high air humidity, for example. In spite of the membrane, the encoders retain their high protection class of up to IP67 and are still resistant to harsh environmental conditions.
Choice of materials and processing with a view to environmental compatibility
The newly designed encoder cover is made of die-cast aluminium. So, unlike the die-cast zinc cover which is commonly used on the market, the housing‘s eco-friendly powder coating can be maintained. Customers can therefore choose the colour they‘d like with a clear conscience.
Evidence of our experience down to the smallest of details
A special feature derived from customer requests is the eyelet integrated in the housing cover, to which a labelling strip can be attached (e.g. to identify the system / location).
A summary of the key properties:
• Robust standard industrial encoder
• Die-cast aluminium housing with particularly eco-friendly powder coating
• Up to 25,000 pulses thanks to high-quality electronics
• Protection class of IP67; shaft sealet to IP65
• Immunity to interference
• Extremely high bearing load: up to 500 N in axial / radial direction
• Maximum mechanical and electrical safety
• Full connection protection at 10 VDC up to 30 VDC
• High output frequency of up to 600 kHz / 2 MHz
• Operating temperature with connector outlet: -40 °C to +85 °C
• Optional: pressure compensation membrane
