Allen-Bradley 845F-SJEZ23CFYR5 Optical Incremental Encoder

The Allen-Bradley 845F-SJEZ23CFYR5 Optical Incremental Encoder is a compact rotary position sensor that delivers reliable incremental feedback from rotating machinery when powered from 8-24 V DC. It is housed in a rugged NEMA 4/13 enclosure (Size 25) and includes an integral flexible shaft coupling to simplify mounting in challenging environments. This 845F variant provides 80 pulses per revolution (PPR), delivering mid-range resolution for precise speed and position sensing across a variety of automation tasks. The encoder is designed for high-speed operation, offering a frequency response up to 210 kHz to accurately track rapid shaft motion. As part of the Rockwell Automation Allen-Bradley 845F family, the SJEZ23CFYR5 configuration aligns with standard engineering practices for optical incremental sensing and is intended for integration with typical Allen-Bradley control systems and wiring schemes, making it a practical choice for industrial automation applications requiring dependable, durable feedback from a compact, field-proven encoder.
