MITSUBISHI OSA105S5 Rotary Optical Encoder (OSA Series)

• Encoder Type: Rotary Optical Absolute Encoder
• Resolution: Approximately 1,000,000 pulses/counts per revolution (10⁶ pulses/rev).
• Output Interface: High-speed serial digital data (transmitting digital gray code signals).
• Mounting Design: Hollow shaft architecture designed for direct, rigid integration onto the motor shaft.
• Lifecycle Status: Discontinued by the manufacturer. Official technical documentation from Mitsubishi Electric notes that the original component is officially substituted and succeeded by model OSA105S5A.
• Elimination of Homing Cycles: Because it tracks absolute positional data rather than incremental pulses, the system retains the precise location of the machine axes during a power failure or shutdown. Operators do not need to perform a time-consuming machine homing routine upon rebooting.
• High-Precision Closed Loop Feedback: The high pulse-count resolution ensures exceptionally smooth motion profiling, minimized torque ripple, and microscopic positioning accuracies required for tight-tolerance CNC tooling and rapid automation tasks.
• Optical Contamination: Oil, grease, or dust entering the encoder housing and clouding the glass code disc.
• Cable Degradation: Cracked or poorly shielded serial cables inducing digital noise into the grey code stream.
• Internal Component Fatigue: Degradation of the internal LED light source or photodiode receiver array over years of high-vibration runtime.
