BEI H25D-SS-CCW-8NBL-7273-EM20 924-01012-118 Rotary Encoder

BEI Sensors H25D-SS-CCW-8NBL-7273-EM20 is an absolute optical rotary encoder in the BEI H25D family, designed to deliver a fixed angular position when power is applied and to report position data via an EM20 cable/interface option. The CCW designation indicates the direction sense encoded in the model, and the EM20 variant reflects BEI’s connector/interface family used for robust wiring. Related catalog references confirm configurations in the H25D family with 28 V operation and open-collector outputs (for example, H25D-SS-CCW-8GC-28V/OC-EM20-S), which supports rugged industrial wiring, and cross-references like 924-01012-118 appear in distributor listings for BEI encoders. As an absolute encoder, this device provides an exact position value for each rotation, unlike incremental encoders which only indicate movement since last reset. When selecting this variant, verify the exact voltage, output type, and connector configuration against the specific sub-model in your procurement lot and BEI/Sensata listings to ensure compatibility with your controller and wiring harness.
