These transducers are shaft encoders which give absolute measurements on more than one revolution of their shaft.
The encoders have a mechanic gear train which transmits the movement of its master disc to a series of slave discs for shaft revolution counting.
An electronic circuit cancels any mechanic backlash of the gear train, thus yielding a detection's.
They are mechanically strong and properly engineered in their electronics, optical and mechanic parts, being thus able to withstand heavy duty conditions.

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.

Absolute encoders
Singleturn
Absolute encoders provide a specific numerical value (code value) for each angular position.
Multiturn
Multiturn encoders not only detect angular positions but also distinguish between several revolutions.

POSIC introduces the world’s smallest incremental inductive encoder kit ID1101 for linear and rotary applications. It measures only 8.7 x 6.3 mm with a thickness of 0.8 mm and has an A quad B output stage that runs up to a frequency of 200 kHz. The linear/rotary target is a 0.8 mm thick strip/disc that comes in different lengths/diameters.
The linear resolution ranges from 1 um at a speed of 0.5 m/s to 150 um at 50 m/s.
The rotational resolution depends on the disc diameter and is for example 12 bits (1024 A-B pulses per revolution) with a 30 mm diameter disc.
Typical applications are in the motion-control domain with magnetic actuators like brushed and brushless motors, voice coil actuators, linear drives and more. Markets served include industrial, automotive, robotics, medical, instrumentation, laboratory automation, office equipment.
