  XR85 SMARTSafe 8.5" modular rotary incremental quadrature encoders are a breakthrough in hazardous duty encoders.  They are ATEX and UL approved and offer incredibly reliable no-bearing construction!  SMARTSafe encoders can be used in gas and ATEX dust hazardous environments.  Also available:  hollow shaft models (XR45, XR47, XR685), shafted models (XR4F, XR485), and no-bearing modular encoders to fit other flange sizes (XR56, XR67, XR115, XR125, XR850).
  
  For Level 2 applications requiring ATEX/IECEx Zone 2 or 22 or UL Class I, Division 2, Groups A,B,C,D use the XR85 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 XR85 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 relying on a tiny optical encoder with weak bearings, install the most rugged encoders available for your drilling or industrial applications.  Vibration, shock, liquids, dust and dirt won't harm SMARTSafe encoders!  Paint booths, draw works, coil tubing rigs...XR85 can keep them all working 24-7-365.
  
  Eliminate the biggest cause of industrial encoder failure--eliminate the bearings with XR85 hazardous duty encoders
