What Micronor Inc. does

Micronor Sensors Inc. is a privately held, Camarillo/Ventura, California-based manufacturer of fiber optic kinetic sensors founded in 2003. The company designs and sells passive fiber optic sensors and matching active signal conditioners/controllers for applications where electronic sensors cannot function, including MRI bores, high-voltage transformer windings, railway pantographs, mining explosive atmospheres, and semiconductor plasma environments. Its core technology stack combines Gallium Arsenide (GaAs) crystal temperature sensing with optical spectral imprint and Fiber Bragg Grating (FBG) techniques, producing temperature probes, absolute and incremental encoders (MR330/MR340/MR430/MR431), emergency stops (MR387/MR388), microswitches (MR386), multi-axis accelerometers (MR660), and miniature robotic force sensors (Femto). Notable technical specifications include temperature accuracy of ±0.2°C across -200°C to +300°C, encoder resolution up to 25-bit, link distances up to 2,000 meters for glass fiber, and emergency stop ranges to 10 km.

The company's product portfolio also includes electromechanical resolvers, encoders, and draw-wire/measuring-wheel sensors, giving it the ability to bundle fiber optic and conventional electronics from a single source. It sells under three sub-brands: ZapFREE (passive position sensors), FOTEMP (temperature systems via partnership with COMEM/Optocon AG), and Femto (optical force sensors for robotics). Distribution is global direct sales via website e-commerce, email, phone, and trade-show presence (notably Sensors Converge 2026), supported by free configuration software and email-based technical support.

Micronor monetizes primarily through one-time hardware sales, with unit ASPs ranging from $550 for general-purpose temperature probes to $7,420 for extended-range two-channel portable thermometers, plus quote-based OEM and industrial system sales. Customer segments are predominantly enterprise: medical/MRI (Philips Research, Imagion Biosystems, Polymer Robotics), transportation/railway (Frey AG, Las Vegas High Roller), energy/utilities, industrial manufacturing, mining, and semiconductor. The company is small (1-10 employees), self-funded with no disclosed outside capital, and operates without a public parent, recent acquisitions, or leadership changes in the available data.
