BEI Sensors H38D-CCW-8GC-7273-SC-UL Rotary Encoder

BEI Sensors H38D-CCW-8GC-7273-SC-UL is a rugged optical rotary encoder that delivers absolute position feedback for equipment operating in hazardous environments. As a member of BEI’s H38D family, this CCW variant uses an 8-bit Gray Code (8GC) output and carries UL recognition with the SC-UL designation, signaling compliance for safe use in controlled industrial settings. Powered from 7.5 to 24 VDC, the encoder relies on optical sensing to report the exact angular position on power-up, providing instantaneous, reference-free position data. The 8GC coding scheme encodes position in 8-bit Gray code, which helps maintain reliable readings in electrically noisy environments and reduces readout errors during transitions. Designed for industrial automation and safety-critical machinery in hazardous locations, the H38D-CCW-8GC-7273-SC-UL combines BEI’s proven optical technology with explosion-proof construction to withstand demanding installations. Its combination of absolute-position capability, CCW orientation variant, and UL/SC-UL safety certification makes it well-suited for applications where precise, robust feedback is essential and compliance with safety standards is required.
