Micronor Passive Fiber Optic Incremental Encoders ATEX

Supplier: Quality in Control

Micronor MR310/MR320 series are the only 100% Passive Fiber Optic Incremental Encoders available in the market, ATEX approved for hazardous locations and explosive environments.

Price Guide: POA

This range of Fiber Optic Incremental Encoders features an innovative designbased on a non-electrical, all-optical passive sensor linked to a remote interrogator module via a industry-standard fiber optic link.

Fiber optic encoders provide interference-free feedback in challenging environments such as mines, steel mills and oil rigs. A typical application where the fiber optic encoder can used is to provide noise-free, closed loop feedback for precise control of a VFD or High Voltage Drive system.

Micronor MR310/MR320 Fiber Optic Incremental Encoders Features include:  

  • Passive optical sensor eliminates need for remote power supply, isolation barriers and EX cabinets
  • Immune to EMI, RFI, lightning, high voltages, and ground loops
  • Standard temperature range -40°C to +80°C; Optional Extended temperature option -60°C to +150°C
  • 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"
  • Can be Installed in non-hazardous location up to 2500 meters away
  • ATEX approved for EPL Mb/Gb/Gc/Db/Dc applications
  • Provides interference-free encoder feedback over long distances
  • Outperforms resolvers and electronics-based encoders in challenging environments
