October 29, 2018 – Micronor introduced the MR430 Size 11 Fiber Optic Position Sensor System, a fiber optic absolute rotary encoder. The sensor is based on Plastic Optical Fiber (POF) technology. This passive, EMI-immune position feedback solution is suitable for operating environments stressed by High Voltage, RFI, Microwave Radiation, Magnetic Fields or Explosive Atmospheres.
In size, the MR430 sensor features a Size 11 (Ø1.1”) form factor suitable for the robotic or actuator mechanism. In performance, the encoder offers 25-bit resolution (13-bit Single Turn + 12-bit Multi-turn) with an update rate of 850µs and ability to operate interference-free over distances up to 30 meters (100 ft). The sensor’s non-metallic construction offers both magnetic immunity and transparency for MRI applications as well as corrosion resistance for industrial environments.
A MR430 Absolute Encoder System consists of the MR430-1 DIN Rail Mount Controller and MR431 Rotary Sensor. The Controller offers a number of built-in interfaces for ease of insertion in the engineer’s design – including SSI, RS485/Modbus RTU, Digital Set Point, and programmable 4-20mA and ±10V analog outputs.
