BEI Sensors HS35F-62-SS-1024-ABZC-28V-SM18-S Optical Encoder

BEI Sensors HS35F-62-SS-1024-ABZC-28V-SM18-S is an optical rotary encoder that delivers precise incremental position feedback for motor and motion-control systems. It provides 1024 PPR in a quadrature with index (incremental) output, enabling reliable detection of rotation and speed with an index pulse for reference. The encoder operates from 5 to 28 V DC and terminates via an SM18-S connector, supporting robust field wiring. Built on an optical sensing mechanism, the HS35F family features a no-detent output and a rugged chassis- or motor-mountable form factor with a shaft actuator; the 62 in the model name indicates a 0.625-inch shaft diameter. The device is rated for up to 7.5 billion revolutions, making it suitable for high-cycle applications, is RoHS compliant and lead-free, and offers user-selectable orientation for flexible installation. Its design emphasizes reliability in industrial settings, with a MSL 1 rating (unlimited), and a straightforward connector termination that simplifies integration into existing control electronics. This variant combines 1024 PPR resolution, a durable optical encoding method, and BEI Sensors’ precision for accurate positional feedback in servo drives, CNC machinery, and other motion-control systems.
