SMARTSafe encoders can be be used in in UL gas gas and and ATEX/IECEx gas gas and and dust hazardous environments Also available: hollow shaft shaft models models (XR45 XR685) shafted models models (XR4F XR485) no-bearing modular modular encoders to fit other flange sizes (XR56 XR85 XR85 XR115 XR125 XR850) and modular modular sensors (XR5 (XR5 XR12) For applications requiring ATEX/IECEx Zone 2 2 2 2 or or or 22 or or or UL Class I I Division 2 2 2 2 Groups A A B C C C D D use the XR850 directly in your application with no barrier isolator or or cable gland required For applications requiring UL Division 1 1 1 ATEX/IECEx Zone 1 1 1 or or or 21 use use the the XRB3 isolator in in in in in your control cabinet which permits the the use use of of of intrinsically safe wiring instead of of of explosion proof conduit or glands The XR850 can also be used in in in in UL Class I I I DIV 1 and and Zone 0 0 applications using the XRB3 Isolator Unlike the competition Avtron SMARTSafe encoder systems are protected against short circuits power-to- output output wiring and output-to-ground faults Instead of mounting a a a a a a a tiny optical encoder with weak bearings on on on on a a a a a a a a a a a wobbling stub shaft shaft mount mount XR850 directly on on on on on your main application shaft shaft Vibration shock liquids dust and dirt won’t harm SMARTSafe XR850 XR850 encoders!
