Prior to the MR318, engineers had no commercial solution for measuring continuous position within an MRI chamber. Motors or actuators could be hydraulic or pneumatic but no commercial, non-metallic position sensor existed. A homemade fiber optic proximity/limit switch was the best solution, but this was awkward to design, package, and could only provide position information at discrete points. The advent of the MR318 enabled fully-functional motion control apparatus with closed-loop feedback.
Encoder Designed for Extreme Electromagnetic Fields

The MR318 Fiber Optic Rotary Encoder is the world's first and only commercially available, non-metallic rotary position sensor that can operate with complete "transparency" in extreme electromagnetic fields. The product concept grew out of requests from the magnetic resonance imaging (MRI) community for a non-metallic version of Micronor's existing fiber optic encoder products.
