Overview
The Mitsubishi RFH1024-22-1M optical encoder is a precision rotary encoder designed for position feedback in industrial automation, CNC machinery, and servo-driven systems. This optical shaft encoder has been discontinued by the manufacturer but remains a critical spare part for legacy equipment maintenance. The encoder provides 1024 counts per revolution of resolution, enabling accurate shaft position and speed monitoring in closed-loop control applications.
Key Features
- 1024 counts per revolution (PPR) optical resolution
- 17-pin Amphenol connector for standard industrial wiring
- 5 volts DC supply voltage
- Compact design with 28 mm shaft length
- Suitable for spindle feedback and servo motor applications
- Proven reliability in CNC and automation equipment
