The RSC Series of non-contacting rotary sensors determines measurement angle by detecting variation in the orientation of a magnetic field due to a magnet attached to the shaft. Custom circuitry performs field orientation detection and filtering while providing an analog output that is proportional to angular position.

The units are unaffected by static or dynamic shaft loads of up to 20 N in both radial and axial directions. RSC sensors are designed to operate in extreme industrial environments and provide protection to the IP 65 standard.
