ZapFREE® Fiber Optic Absolute Position Sensor

The MR330 Series ZapFREE® Fiber Optic Absolute Position Sensor measures absolute angular position from 0° to 360° with 0.025° resolution.

This innovative sensor system outdistances conventional absolute encoders and resolvers – transmitting interference-free up to 300 meters! The system consists of a passive optical sensor (MR332) and active controller (MR330) linked via industry standard 62.5/125μm multimode fiber. Interconnect options include commercial Duplex LC or industrial grade ODVA IP-LC Duplex.
