Mitsubishi Electric OSA18-A50 Servo Motor Encoder

The Mitsubishi Electric OSA18-A50 Servo Motor Encoder is a high-precision feedback device designed to mount directly on Mitsubishi OSA18-series servo motors to deliver accurate position and speed data for closed-loop motion control in CNC machines, robotics, and automated equipment. It supports absolute or incremental encoding depending on the series and provides position and speed outputs (A/B/Z or serial) to a Mitsubishi-compatible servo drive for reliable synchronization. Built for industrial environments, it uses an enclosed housing, operates from servo-drive power, and delivers a high-speed response rated up to the 50 kHz class with high-resolution feedback suitable for precise motion tasks. Common replacements include Mitsubishi OSA18-A30 and Mitsubishi OSA18-100, reinforcing compatibility within the Mitsubishi servo motor ecosystem and related encoder options.
