BEI SENSORS 924-01002-973A Photoelectric Sensor

BEI SENSORS 924-01002-973A is an incremental optical rotary encoder that provides precise rotational position feedback for motion-control and automation systems. Built with an aluminum housing and designed for flange or servo-mount installations, it supports multiple bolt-hole patterns for flexible mounting in tight spaces. The variant H25D-SS-256-AB-7406R-LED-EM16 indicates a 256 PPR resolution with A and B channel outputs and a LED-equipped version, suitable for inline feedback in servo drives and CNC machines. Electrical specifications include a 5–26 VDC supply and a maximum shaft speed of 5,000 RPM, making it compatible with a wide range of servo motors and drive systems. The encoder offers a selectable resolution range from 1 to 2,540 PPR, allowing users to tailor precision and signal bandwidth to their application. It is described as non-hazardous, adding suitability for standard industrial environments. With BEI SENSORS’ reputation for rugged optical encoders, this module provides reliable, high-resolution feedback essential for closed-loop control, motion profiling, and synchronization tasks in manufacturing lines and robotics. The part number 924-01002-973A helps ensure the exact bolt-pattern and electrical configuration needed for replacement or upgrades in existing BEI SENSORS installations.
