BEI H25E-F1-SS-1250-ABZC-8830-LED-EM18,924-01002-3875 Rotary Encoder

BEI H25E-F1-SS-1250-ABZC-8830-LED-EM18,924-01002-3875 Rotary Encoder is a 2.5-inch optical incremental encoder from BEI Sensors (Sensata Technologies) designed to deliver high-resolution rotary position feedback for industrial automation. As part of the BEI H25 Gen 2 family, it provides A and B channel outputs with an index (Z) signal for precise motion tracking using optical sensing. The H25 series is engineered for rugged environments, offering up to IP66 sealing for resistance to dust and washdown conditions. The device’s 2.5-inch (63.5 mm) body diameter aligns with common mounting footprints on servo drives, CNCs, and automation equipment, enabling straightforward replacement or integration. The model code’s 1250 segment indicates a specific disc resolution within this lineage, supporting applications that require stable, high-precision feedback for speed and position control. Typical use cases include CNC machines, robotics, packaging and material-handling systems, automated machining, and other industrial applications where reliable incremental feedback improves control loop performance. BEI’s H25 family devices are designed to work with BEI/Sensata drive electronics and standard industrial interfaces, providing durable, long-life position sensing for continuous operation in demanding environments.
