BEI Industrial XH20DB-37-SS-250-ABZC-7272-SM18-24V,924-01039-1981 Encoder

BEI Sensors XH20DB-37-SS-250-ABZC-28V/V-SM18 is a 20 mm hollow-shaft incremental encoder from the XH20 family, offered in the stainless-steel SS variant for rugged industrial service and a compact form factor. It delivers 250 pulses per revolution (PPR) through a two-channel incremental interface with an index output (Z), and it uses an SM18 18-pin connector for reliable wiring in harsh environments. Powered from a DC supply in the 5–28 V range, this model carries the 28V variant designation in its part-number suffix and is cataloged as 01039-1981 by BEI/Sensata distributors, enabling integration with servo drives and motion controllers where precise speed and position feedback is required, with the stainless-steel SS housing variant designed for harsher environments. Designed for use in robotics, automation, and packaging equipment where space is at a premium and reliability matters, the XH20DB-37-SS-250-ABZC-28V/V-SM18 provides compact, robust rotational sensing suitable for line automation, CNC tooling, and conveyor feedback loops.
