BEI H25D-SS-2000-ABC-8830-LED-SM16 Rotary Encoder

BEI H25D-SS-2000-ABC-8830-LED-SM16 is an optical incremental rotary encoder in BEI’s H25D family that provides high-resolution feedback with 2000 pulses per revolution (PPR). It outputs a quadrature signal with an index pulse, enabling precise tracking of rotation direction and a reference position within each turn. The encoder is designed for a 5 to 28 V DC supply and uses an SM16 16-pin connection for wiring. Its actuator is a shaft, and the package is intended for chassis-mount installation, which supports stable mounting in compact spaces. Users typically integrate it with servo drives and PLCs that support encoders, enabling closed-loop position control and precise speed feedback. The inclusion of an index pulse offers a repeatable home reference within each rotation, aiding calibration and multi-axis synchronization in automation, robotics, CNC, and packaging equipment where reliable, high-resolution feedback is essential.
