The MR310 Remote Encoder Interface (REI) Module is the remote optoelectronic interface for any of the MR3XX ZapFREE(tm) Fiber Optic Rotary Encoders. The module operates from 24VDC and mounts on standard 35mm DIN rail. The module converts the encoder's optical signals to standard A/B quadrature signals and provides other internal features, functions and electrical interfaces:

The world's first, totally passive fiber optic incremental rotary encoder - the premier rotary sensor for harsh and hazardous environments. The MR312 encoder links to the MR310 REI module via a single 62.5/125 multimode fiber terminated with industry-standard ST-PC optical connectors. Link lengths can extend up to 1000m. Packaged in an industry-standard 58mm OD encoder package, the shafted MR312 series is offered with resolution options of 100, 128, 256 and 360ppr. Standard temperate range is -40C/+80C while the Extended Temperature option is -60C/+150C. ATEX certified.

This higher resolution version of the original ZapFREE Encoder offers 1024ppr in an industry-standard 100mm OD hollow shaft encoder package. The MR314 encoder links to the MR310 REI via a single 62.5/125 multimode fiber terminated with industry-standard ST-PC optical connectors. These remotelinks can exttend up to 1000m. Temperature range options include standard (-40C/+80C) and Extended (-60C/+150C). ATEX certified.

MR316 series is a heavy duty encoder in industry-standard 90mm housing. Resolution options are 100, 128, 256 and 360ppr. The MR316 encoder links to the MR310 REI module via a single 62.5/125 multimode fiber terminated with industry-standard ST-PC optical connectors. These remotelinks can extend up to 1000m. Temperature range options include Standard (-40C/+80C) and Extended (-60C/+150C). ATEX certified.

MR318 series is a special version of our ZapFREE(tm) fiber optic encoders which is totally completely passive AND NON-METALLIC - designed for use in MRI facilities. The encoder follows the same Size 58mm form factor of the MR312 series and features a 5m optical pigtail so that the metal ST connector is outside the MRI active area.

The MR320 series offers an off-the-shelf, industrial-grade cable assembly solution for connecting a ZapFREE(tm)Fiber Optic Encoder to the MR310 interface module. These cable assemblies incorporate our M06 industrial grade, indoor/outdoor multimode 62.5/125 simplex cable which is so rugged - you can run a truck over it.

TD5207 is a special version of our ZapFREE(tm) fiber optic encoders which is totally completely passive AND NON-METALLIC - designed for use in MRI facilities. The long fiber optic pigtail connects to an MR310 module outside the MRI area. As of Nov-08, the TD5207 was replaced by the MR318 series - which uses the same form factor as our standard "metallic" MR312 series.
