BEI Sensors H25E-F1-SS-12NB-28V OC-CW-ECS18 Encoder

BEI Sensors H25E-F1-SS-12NB-28V OC-CW-ECS18 is a 12-bit natural-binary incremental encoder from BEI’s H25 family, delivering precise rotary position information through optical encoding. It operates from a 5–28 VDC supply and uses open-collector outputs, with clockwise increasing count (CW) encoded in the model designation. The ECS18 suffix denotes a specific connector/cable configuration for this variant. As part of BEI’s flagship H25 line, the device is designed for robust rotary-position feedback in automation and machinery, enabling reliable discrete position reading in manufacturing, robotics, and motion-control applications. The 12NB coding provides 12-bit position data per revolution, supporting interfaces on industrial controllers that expect binary-position inputs. This variant’s 28V/OC interface is compatible with standard open-collector input stages and suits a broad range of automation platforms requiring a 5–28 VDC supply and OC outputs.
