         DURABILITY
         What use is a hazardous duty encoder if it fails
         to work? Many “hazardous duty” encoders from
         the competition are merely repackaged weak
         optical encoders.

         Avtron hazardous duty SMARTSafe XR encoders
         are heavy and severe duty units, with potted
         electronics, magnetic sensors and huge bearings
         or no bearings at all!
                                                        XRB1 isolator for remote installation; XR4F, XR45 incremental encoders with Level
         Nidec-Avtron offers a full range of SMARTSafe XR   2 Local Protection
         encoders including shafted, hollow shaft, and   LEVEL 1 PROTECTION
