Baumer BMMH 30 SSI - MAGRES

Absolute encoder

The BMMH 30 SSI - MAGRES is a mini absolute encoder from Baumer, designed for high-precision applications. It features a hollow shaft and provides SSI (Serial Synchronous Interface) communication. This encoder uses magnetic sensing for position measurement and offers both single-turn and multi-turn resolutions.
