Fiber Optic Rotary and Linear Encoders
Micronor MR330 / MR430 series Absolute and MR340 series Incremental Encoders are 100% Passive Fiber Optic Position Sensors. The innovative design is based on an all-optical passive sensor and remote interrogator module interconnected by an industry-standard multimode fiber optic link. Features include:
- Passive sensor requires no remote power supply, isolation barriers or EX cabinets
- Immune to any electro-magnetic interference such as lightning, radiation and magnetic fields
- Sensors are Ex classified “simple mechanical device” and can be installed in all manner of hazardous locations and explosive environments – mines, gas and dust
- Controller provides “inherently safe, optical radiation” and can be installed in non-hazardous location
- ATEX approved for EPL Mb/Gb/Gc/Db/Dc applications
- Provides interference-free position feedback over long distances
- Outperforms resolvers and electronics-based encoders in harsh and hazardous environments
