Fiber-optic absolute position sensor is MRI-compatible
Long-distance sensing without interference at up to 300 meters is possible with the absolute rotary encoder system. The MR330 controller transmits a burst of light to the code disk in the sensor, which modulates the spectral components of the light based on angular position. Position information is imprinted in the optical spectrum of the light and guided back to the controller for precise position readout. Built-in controller interfaces include SSI, USB, RS-485, RS-232, Modbus, digital, and analog.
