Wachendorff Automation developed the basis for a new generation of single-turn and multi-turn absolute encoders in 2009 using EnDra technology. These encoders can operate without a buffer battery and without a gear unit, thus making them maintenance and wear-free. These days the absolute encoders with CANopen, SAE J1939, SSI, and RS485 interfaces are established in many series productions across the world.
With the new range of single-turn and multi-turn encoders for PROFIBUS, Wachendorff Automation is now taking the next step towards becoming a series production supplier of high-precision sensors for drive units and engines in machine and plant construction. Not only has Wachendorff integrated the PROFIBUS protocol, it has also developed solutions with efficiency for the user in the field of mechanics and electronics: The low installation depth of just 60.7 mm supports progressive miniaturisation in machine construction.

The PROFIBUS encoders are available with a bus cover or with housing connectors. The bus cover is designed for cable and connector solutions. As a result, varied connection types can be achieved. The interface can be configured by the user for classes 1 to 4 using the GSD file. Two separate LEDs for displaying the operating status and bus monitor make start-up easier for the user.
Alongside the standard in machine construction, the WDGA58B with 58 mm-trim ring and varying metric and inch shaft diameters, the heavy-duty configuration WDGA58D with the high bearing loads 400 N axial and 400 N radial as well as the hollow shaft version WDGA58E are other models in the Wachendorff range.

Motorfeedback Encoder
The WDGF motorfeedback encoder, equipped with a tapered shaft and a specifically designed torque support, is quick and easy to integrate into the motor housing. The precision ball bearings are designed for continuous operation at 12,000 rpm and thus guarantee a high operational stability.
All mechanical and electrical components are designed for high dynamics and demanding environmental conditions. Extreme resistance to vibration (300 m/s² acceleration in the 55 - 2000 Hz frequency range) and shock (2000 m/s² for 6 ms), a high degree of protection (IP 67, shaft sealed to IP 65) and a wide temperature range (-40 °C bis +115 °C) guarantee a long service life.
The accurate singleturn value with 19 bit resolution is transmitted via the 10 MHz BiSS-C interface. Thanks to the optical measuring principle, the unit simultaneously produces high quality 2,048 sin/cos signals per revolution. A two-colour LED fitted to the back ensures a fast start-up even under adverse installation conditions.
