Part no.: Micronor MR430 Fiber Optic Encoder
• 100% passive sensing design no electronics whatsoever
• Linear and rotary sensor configurations
• Sensor can be installed in all manner of hazardous locations and potentially explosive atmospheres
• Immune to EMI and RFI
The MR430 series ZapFREE® Fiber Optic Position Sensor is a small form factor, rotary position sensor with 13-bit, single-turn resolution.
The MR430 features an innovative design which enables new applications and OEM product features not formerly possible with electronics-based sensors.
The sensor is 100% passive and is unaffected by EMI, RFI, microwaves and magnetic fields. The innovative, alldielectric design also provides 100% electrical isolation and immunity to high voltages & lightning.

All absolute rotary encoders have a rotor which is attached to the rotating shaft and a stator which is attached to the housing holding the shaft. The interaction of these two components produces a measure of the shafts rotational angle. The most important parameters of absolute rotary sensors are resolution, accuracy and tolerance to misalignment of the rotational axes.
Recently, obtaining the Inductosyn and components for maintenance has become more difficult. For decades the Inductosyn from Farrand Controls / Ruhle Companies sat near the top of the rotary sensor hierarchy. Providing sub 2 arcsec (0.5 mdeg) accuracies, it combined the robustness of a resolver with the performance of the best optical encoders. Despite its shortcomings, it found plenty of customers, from airborne infrared and radar systems, to telescopes, satellite communication antennae (SATCOM), machine tooling and low-pressure vacuum chambers.
Read how Micronor’s fiber optic encoders provide an inherently safe sensing option with immunity to lightning, radiation and magnetic fields.
Synchronous Serial Interface (SSI) is a widely used serial interface standard for industrial applications between a master (i.g. controller) and a slave (i.g. sensor).
