New source for Wachendorff Automation absolute encodersVariohm Eurosensor is releasing a new range of competitively priced high-resolution single/multiturn absolute rotary encoders from German position sensor specialists Wachendorff Automation GmbH.

The innovative WDGA series features an on-board 32-bit processor and full CANopen interface that handles the conversion of the encoder's rugged magnetic position technology to output 4096 steps/rev (12-bit) at rates up to 1Mbaud and with a multi-turn capacity of 131072 revs (17-bit). The WDGA series is suitable for space-limited applications as a feedback device for positioning systems requiring long life and low maintenance – and unit pricing is estimated at 30 per cent below comparable technology.

Built for resilience, the WDGA is also very compact with a nominal 36mm diameter aluminium housing and stainless-steel shaft with dual low-friction precision bearings. Protection rating is to IP67 with shaft sealing to IP65 (optional IP67) and operating temperature range is -40 to +80degC. Mounting alternatives are via standard 36mm diameter synchro/resolver flange mount, a 58mm diameter clamping flange or 6mm diameter blind hollow shaft. Maximum speed for the clamping flange version is 12,000rpm.

Extensive CANopen functionality includes a DS301 communication profile and DS-406 device profile. Position speed and acceleration output is included along with work area supervision, encoder cam and scaling capability plus comprehensive diagnostics.
