BEI h20db-47-f5-ss-400-a-3904-sm14-12v-s Rotary Encoder

BEI h20db-47-f5-ss-400-a-3904-sm14-12v-s Rotary Encoder is a BEI Sensors H20 Express incremental encoder designed for rugged industrial motion control. It provides 400 pulses per revolution, with a shaft seal (SS) for added protection in dusty or lubricants-heavy environments, and it runs from a 12 V DC supply. The unit uses a 14-pin SM14 connector and employs a 3904-based output scheme, aligning with BEI's Express family signaling to support straightforward interfacing with standard controllers and drivers. This encoder is compact enough for tight installations while delivering repeatable position feedback in CNC machining, robotics, and automated manufacturing setups. Designed to endure demanding applications, it is commonly paired with servo drives, PLCs, or motion controllers that accommodate BEI’s transistor-based output configurations, offering reliable incremental feedback across a wide range of factory environments.
