Allen-Bradley 845H-SJHZ26CPYR5 Optical Incremental Encoder

The Allen-Bradley 845H-SJHZ26CPYR5 Optical Incremental Encoder delivers precise rotary position feedback for automation and motion-control systems. Operating on 8–24 VDC, it provides 1,800 pulses per revolution for reliable resolution, and a 210 kHz frequency response to support high-speed feedback. Its enclosure is rated NEMA 4/Type 13, offering protection against dust, water, and wash-down environments, while the Size 25 package keeps the footprint compact for tight installations. As a member of the 845H family, this model uses optical sensing to deliver dependable incremental signals suitable for use with standard Rockwell Automation control architectures and other automation equipment that relies on robust, rugged feedback sensors in demanding industrial settings. This encoder is well-suited for applications requiring precise speed and position feedback in conveyors, packaging lines, and automated machinery where durable performance under harsh conditions is essential.
