Fiber Optic Absolute Rotary Encoders

Fiber Optic Absolute Rotary and Linear Encoders and Position Sensors

Micronor Inc. offers two series of fiber optic type absolute rotary encoders; the MR330 and MR430 series. Both are based on an all-optical passive sensor and remote interrogator control module.

The MR330 series is the product of choice for longer distances, outperforming any electrical system. The MR430 series is the product of choice for small form factor and budget reasons without compromising on system performance.
