Mitsubishi Electric OSE253S2 Servo Motor Encoder

The Mitsubishi Electric OSE253S2 servo motor encoder delivers high‑resolution position and speed feedback for industrial motion control systems. This incremental optical encoder provides 2500 pulses per revolution (PPR) with differential A, B, and Z outputs, designed for use on Mitsubishi AC servo motors in CNC machines, robotics, packaging equipment, and automated production lines. Typical supply voltage ranges from 5 to 12 VDC depending on variant, and the line‑driver differential interface ensures robust signal integrity in harsh environments. The unit features either a blind hollow shaft or a solid shaft depending on mounting, and it is installed using a servo motor mounting adapter compatible with Mitsubishi servos, with a factory‑configured cable/connector tailored to application needs. Built for industrial ambient temperatures, its rugged design delivers vibration and dust resistance to support reliable operation in demanding automation tasks. Compatibility is tailored for Mitsubishi MELSEC and MELSERVO systems, making it a straightforward replacement or upgrade for feedback accuracy in existing networks. Common replacements include Mitsubishi OSE253S1 and OSE230S2, offering similar performance for the same family of servo controllers.
