Mitsubishi Electric OSA18-100 Absolute Encoder

The Mitsubishi Electric OSA18-100 Absolute Encoder is an absolute rotary encoder that delivers precise position feedback for servo motors in industrial motion control systems, outputting a digital position feedback signal. Designed for direct motor-mounted installation on Mitsubishi servo motors such as the HC-SFS series, it supports CNC machines, machining centers, and automated production equipment that require high-accuracy feedback. As part of the OSA18 Encoder Series, the OSA18-100 uses an industrial-grade housing to provide reliable position data in demanding environments and serves as a legacy replacement part. Common replacements for this part include Mitsubishi OSA18-130 and OSA18-A50.
