Optical Serial Encoder – MITSUBISHI OSE105S2
The OSE105S2 is an optical serial rotary encoder (“Optical Serial Encoder”) manufactured by Mitsubishi Electric, designed as a feedback device for HC-series servo motors (HC-KFS, HC-MFS, HC-SFS) paired with MELSERVO MR-J2S servo amplifiers and MELDASMAGIC / MELDAS CNC systems. The device transmits rotor angular position and speed signals to the servo amplifier via Mitsubishi’s proprietary serial protocol. Available as a standalone unit for direct shaft mounting; encoder cable not included.
The position encoder is the sensor that closes the servo amplifier’s feedback loop: it transmits the motor’s angular position and speed in real time, allowing the controller to instantly correct any position or speed error. Without it, the servo amplifier triggers an encoder alarm and disables the motor; incorrect or missing feedback causes loss of positional accuracy, axis vibrations, and potential machine collisions.
Mitsubishi Electric is one of the world’s leading manufacturers of industrial automation and CNC systems, covering the MELSERVO (servo drives), MELDAS / MELDASMAGIC (CNC controllers) and MELSEC (PLC) product lines. HC-series motors paired with MR-J2S amplifiers are legacy / discontinued: superseded by the MR-J3, MR-J4 and MR-J5 platform; OSE encoders for these motors are available exclusively as used, surplus or original warehouse stock.
