BEI Encoder Division H20DB-37TS-SS-1000-A-3904R-SM14-5V Rotary Encoder

BEI Industrial's H20DB-37TS-SS-1000-A-3904R-SM14-5V is a 1000-count-per-revolution incremental rotary encoder from the BEI H20 family, delivering A and B quadrature signals with an index (Z) for precise rotor position feedback. It uses an SM14 (MS3102R14S-6P) mating connector and is configured for a 5 VDC supply, with the 3904R option denoting this specific output configuration. The encoder supports a base frequency response around 100 kHz (1024 CPT), with interpolation options boosting performance up to about 400 kHz for higher-speed applications. This combination of high resolution, robust BEI construction, and standard mounting interfaces makes it suitable for servo feedback and motion-control tasks in industrial automation where reliable, high-precision feedback is required.
