XR5 (SMARTSafe™) Sensor

XR5 SMARTSafe™ modular sensors enable the world's first hazardous duty encoders with removable electronics.  They are cULus, ATEX and IECEx certified and offer incredibly reliable no-bearing construction!  SMARTSafe sensors can be used in ATEX/IECEx gas and dust and UL gas hazardous environments.  Also available:  hollow shaft models (XR685), shafted models (XR485), no-bearing modular encoders (XR125XR850), and modular sensors for larger bore applications (XR12).

For Level 2 applications requiring ATEX/IECEx Zone 2 or 22 or cULus Class I, Division 2, Groups A,B,C,D use the XR5 directly in your application, with no barrier, isolator or cable gland required.

For Level 1 applications requiring ATEX/IECEx Zone 1 or 21 protection use the XRB1 or XRB2 isolator in your control cabinet which permits the use of intrinsically safe wiring instead of explosion proof conduit or glands. The XR56 can also be used in UL Class I Div 1 & Zone 0 applications using the XRB2 Isolator. 

Unlike the competition, Avtron SMARTSafe encoder systems are protected against short circuits, power-to-output wiring, and output-to-ground faults.

Instead of mounting a tiny optical encoder with weak bearings on a wobbling stub shaft, mount XR5 directly on your machine and install the rotor on your main application shaft.  Vibration, shock, liquids, dust and dirt won't harm SMARTSafe XR5 encoders!  Paint booths, draw works, coil tubing rigs...XR5 can keep them all working 24-7-365.

Eliminate the biggest cause of industrial encoder failure--eliminate the bearings with XR5 hazardous duty encoder sensors.
