Overview
The BEI HS25F-62-R10-BS-1024-ABZC-4469-SM12-EX-S is a precision incremental optical encoder from Sensata-BEI Sensors. This 1024 PPR (pulses per revolution) encoder delivers accurate position and speed feedback in motion control and automation systems. The 2.5-inch hollow shaft design with 0.625-inch bore accommodates direct coupling to motor shafts, eliminating the need for external gearboxes or adapters. With dual-channel quadrature output and index pulse, this model integrates seamlessly into PLC and drive-based control loops.
