Micronor ZapFREE Fiber Optic Rotary Encoder products apply fiber optic technology in new and innovative ways for automation and motion control applications operating in harsh and/or hazardous environments. Micronor makes Fiber Optic Rotary Encoder technology as easy to use (if not easier) as conventional electrical/copper based products.

Fiber Optic Rotary Encoder Offers EMI Immunity for Motion Control ApplicationsMicronor MR318 ZapFree Fiber Optic Rotary Encoder is an entirely passive, intrinsically safe, non-metallic fiber optic rotary encoder – designed specifically for use in Magnetic Resonance Imaging (MRI) systems used in hospitals, medical research and industrial applications. There are no integral electronics within the encoder housing and the all-optical design requires just a single 62.5/125 MM optical fiber connection – the utmost in simplicity, reliability and ease of installation.

Downstream, The MR310 series is a Fiber Optic Incremental Encoder system. MR310 Remote Encoder Interface (REI) module converts the optical signals to an array of standard electrical outputs (both quadrature and analog) for interfacing to conventional counters, PLCs or computer interface boards. An RS232/RS422/RS485 serial interface is also provided for ease of interface to computers and PCs.

Featurea and Benefits of MR318 Fiber Optic Rotary Encoder

  • 100% passive sensing design and intrinsically safe
  • Immune to EMI, RFI and ground loops – ideal for AC and VFD drive applications
  • Constructed from non-metallic materials to be compatible with MRI systems
  • Insensitive to EMI and RFI for use in and around medical equipment and “noisy” industrial environments
  • Immune to electrical static that “zaps” conventional encoders
  • Outdistances copper, link lengths to 1000m
  • Standard model designed to operate in ambient laboratory environment
  • Higher resolution and other form factors can be engineered for special applications
