Industrial 225A-18-0500-PU-N-N-J Rotary Encoder

The Accu‑Coder 225A‑18‑0500‑PU‑N‑N‑J is a 2.25‑inch thru‑bore incremental encoder with a 7/8‑inch (0.875") bore, designed for through‑shaft installation and straightforward integration into motor and drive feedback loops. This is the single‑channel 225A variant offering 500 pulses per revolution (PPR) with a pull‑up (PU) option for simpler interfacing in low‑noise environments. Rated up to 400 RPM, it provides reliable tach feedback for moderate‑speed applications such as motor speed sensing and basic open‑ or closed‑loop control in automation systems. As part of Encoder Products Company’s Accu‑Coder family, it supports robust through‑bore mounting on standard motors and is commonly used for straightforward position feedback in servo or DC motor applications.
