The wide diversity of knowledge and experience, built up over many years within the Wachendorff group of companies, has logically konsequent been used to integrate a new product series into the production program. This has resulted in an innovative range of absolute encoders for CANopen, “Made by Wachendorff in Germany”, that are based on the magnetic principle. They come in single or multiturn versions, with a clamping or synchro flange, or as blind hollow shaft encoders.
The WDGA series was first shown at the SPS/IPC/DRIVES 2008 exhibition in Nuremberg and met with a lot of interest.
The Wachendorff absolute encoders are designed in accordance with the communication profile CiA DS-301 and to the device profile for encoders CiA DS-406 V3.2 class C2. An LED is provided for status signalization as per DR303-3. The WDGA absolute encoders can be configured, without a bus cover, via LSS (layer setting services) to DS-308, or optionally via SDO (service data objects). They offer comprehensive CANopen functionality: position, speed and acceleration objects, limit switch and cam switch functions, up to four individually configurable Transmit-PDO (process data objects), Heartbeat and Nodeguarding as well as other comprehensive diagnostic possibilities, which take into account important aspects of safety.
As ever, the WDGA absolute encoders boast an industrially rugged construction, offer a high level of precision measurement and withstand high bearing loads.

By converting shaft rotation into electronic pulses, encoders are used to electronically monitor the position of a rotating shaft. The encoder’s output pulses are counted and evaluated by a control unit to determine machine position and velocity, which provides exceptional accuracy and flexibility when controlling motion. The high mechanical and electronic operating speeds associated with optical encoders increase system speeds and accuracy, decrease cycle times, and boost overall productivity in the manufacturing environment. Autonics rotary encoders of various sizes and types offer high-quality and precise measuring of the operating position and speed of the rotating shaft, etc. for more precise control of the objects.
