Overview
The BEI Sensors H25E-F1-SS-1024-ABZC-4469-LED-SM12-S is a precision optical incremental rotary encoder designed for servo motor feedback and industrial motion control. This encoder delivers 1024 counts per revolution with complementary dual-channel output and index pulse for absolute position reference. The LED light source provides reliable optical detection, while the SM12 connector and servo motor flange mount enable quick integration into existing automation systems.
