MR304 and MR320 Series
Fiber Optic Incremental Encoders
Fiber optic incremental encoders are typically used to sense the motion and speed of a motor shaft or linear actuator where conventional electronics-based encoders and resolvers are inadequate. Typically the user’s control system is looking for A/B quadrature signals for which electro-magnetic interference and noise causes system errors.
Fiber Optic Absolute Encoders
The MR330 Fiber Optic Position Sensor measures absolute angular position from 0° to 360° with 13/14 bit resolution and multiturn tracking up to 12 bits (4096 turns). The system can operate at full accuracy at speeds > 2500 rpm and distances > 300 meters. This sensor system uses a novel optical spectral imprint technique.
