MICRONOR – Fiber Optic Kinetic Sensors


Micronor Inc. was founded 2003 in Newbury Park, California. The founders accurately predicted the need for fiber optic kinetic sensors which provide immunity from lightning, EMI/RFI, radiation and magnetic fields. Based on an innovative and patented technology, using wavelength as the information carrier, the first product introduced to the market were the incremental encoders. These products are used in the transportation, mining, oil and gas industries for position sensing and controlling the speed of VFD drives. As an innovative and flexible company, Micronor offers a wide range of fiber optic sensors as depicted within this brochure.

Incremental Encoders

Fiber optic incremental encoders are used to sense speed or position of a motor shaft or linear actuator where conventional electronics-based encoders and resolvers are inadequate. The A/B quadrature signals are inherently free of noise and electromagnetic interference. Optical encoder links are free of ground loops and may extend beyond 2500 meters, especially useful in in mining applications


Absolute Encoders

Fiber optic absolute rotary encoders are used where it is necessary to track absolute angular position. An absolute encoder retains position when there is loss of power or disconnect to the sensor. These encoders measure absolute angular position from 0° to 360° with a resolution of 0.0258° and multi-turn tracking up to 12 bits (4096 turns). Linear measurement is accomplished by combining the MR332/MR338 sensor with a draw wire module with range options 50m. A special MRI safe draw string system is available.



are used in applications and environments where thermocouples, thermistors and IR cameras cannot be used:
• Electromagnetic, RF, microwave, high voltage and lightning environments
• Potentially explosive (EX) environments, including mines, storage tanks and chemical plants
• Hot spot monitoring in power transformers
• Medical applications, including MRI and X-ray
• Harsh chemical conditions, including radiation environments
• Small size ideal for hard-to-reach areas and catheters
• Extreme temperatures, -200°C to +300°C
