BEI Sensors H25D-SS-5000-T2-ABZC-28V-SM18-S Rotary Encoder

BEI Sensors H25D-SS-5000-T2-ABZC-28V-SM18-S Rotary Encoder is a high-resolution optical incremental encoder designed for demanding industrial environments. It delivers 5000 pulses per revolution (PPR) and provides A, B, and Z (index) outputs for precise position tracking and dependable homing references. Powered from a nominal 28 V DC supply, this model belongs to BEI’s H25D family and uses robust optical encoding to resist electrical noise. The SM18-S suffix denotes the mounting/connector configuration compatible with 18 mm shaft encoders and chassis mounting, making it suitable for compact, rigid installations. Typical applications include CNC machines, robotic actuators, conveyor systems, and other automated equipment where accurate, repeatable rotary feedback at moderate to high update rates is essential. The ABZC channel set supports standard quadrature signaling with an index pulse, enabling reliable absolute referencing within each revolution and straightforward interfacing with common industrial controllers. BEI Sensors (Sensata Technologies) emphasizes rugged construction with EMI considerations and connector/mounting compatibility across the H25 series, allowing integration with controllers that expect four-channel incremental feedback signals at 28 V. This exact variant—H25D-SS-5000-T2-ABZC-28V-SM18-S—bundles high-resolution 5000 PPR, a 28 V supply, ABZC outputs, and the SM18-S mounting format into a single encoder solution for precise motion control tasks.
