Absolute rotary encoder MH900

optical16-bit32-bit

Overview
Multi-turn absolute encoders record angular position plus the number of revolutions. The multi-turn function is achieved either mechanically via an internal reduction gear linked to the drive shaft or implemented electronically.

Measured value and interfaces
The output value combines single-turn angle and revolution count. The calculated value is made available via multiple industrial interfaces depending on model: SSI, CANopen, CAN SAE J1939, RS485, Profibus, Profinet, EtherCAT, BiSS‑C, Parallel, Analog.
