THE SHAFT IS MECHANICALLY COUPLED via two M5 holes. A torque support is adapted to the customer's specific requirements. The stainless steel rotary encoders comply with protection class IP69K, with the result that they can withstand extreme environmental conditions. The operating temperature range extends from -40 °C to +80 °C. The measuring range is 360° with a 12-bit resolution.

The rotary encoder operates contactless according to the Hall principle. The product offers two interfaces. One of them is the CANopen Safety interface.
The encoder meets the requirements according to SIL-2. It is additionally equipped with the UDS boot loader on CAN. Electrical connection is carried
out using a PUR cable.
