The Mitsubishi 0SE1024-3-15-68-8 is an incremental optoelectronic encoder / servo drive encoder designed as a feedback device for Mitsubishi CNC AC servo motors, often supplied in cooperation with Tamagawa/Heidenhain depending on the specific OEM configuration. It mounts directly to the motor shaft, generating a train of pulses proportional to shaft rotation, which the servo drive or CNC controller uses for precise position, speed, and direction feedback in closed‑loop control.
The “0SE1024” designation indicates an incremental encoder with 1024 pulses per revolution (PPR), a common resolution for legacy and mid‑range CNC servo applications, offering a good balance between accuracy and signal bandwidth. Typical variants of this encoder family (e.g., OSE-1024-3-15-68-8-T01/T02) are used on Mitsubishi servo motor series like OSA/OSB/OSA2xx, OSE10x/OSE25x, in machine tools, CNC machining centers, and industrial automation equipment.
The unit is an incremental, optical shaft encoder with standard industrial output signals compatible with Mitsubishi servo drives and PLC/cnc control interfaces. It is normally powered from the servo drive’s low‑voltage encoder supply (e.g., 5 V DC), and provides differential A/B (and often Z) channels, though exact pinout and electrical specs must be taken from the corresponding Mitsubishi motor/drive manual. On the aftermarket, 0SE1024‑3‑15‑68‑8 is widely available as new original, refurbished, or used parts, supplied with warranty (often 3–12 months) for maintenance and replacement of failing feedback devices on existing CNC machines.
