BEI H40A-240-ABC-4469-LED-SC-UL-S Rotary Encoder

The BEI H40A-240-ABC-4469-LED-SC-UL-S Rotary Encoder is an optical incremental encoder from BEI Sensors’ rugged H40A family, engineered for harsh industrial environments. The model provides three output channels (A, B, and C) in an ABC configuration and includes an LED indicator for status visibility, with UL-S recognition noted in the part name. The 240 in the designation is commonly associated with 240 pulses per revolution (PPR), delivering finer resolution suitable for precise feedback in motion-control systems. Designed as a shock‑proof optical encoder, it is well-suited for servo feedback, automation equipment, CNC machinery, robotics, and other automation applications that demand durable, high‑reliability position sensing. The compact, rugged package supports integration with standard servo drives and PLCs that accept incremental ABC encoders, while BEI’s H40 platform is known for robust performance in demanding production environments.
