first By combining Avtron Avtron durable magnetic encoder encoder technology with SMARTSafeTM systems Avtron Avtron has created a a a a a a a a a a a a truly durable solid shaft encoder which can be used in hazardous environments and applications It is ATEX ATEX IECEx & cULus certified SMARTSafe encoders can be used in gas and ATEX ATEX dust hazard environments Also available: hollow shaft shaft models (XR45 XR685) NEMA style shafted model model (XR485) and no-bearing modular encoders (XR56 XR85 XR85 XR115 XR125 XR850) For applications requiring ATEX or or or or IECEx Zone 2 2 2 2 or or or or 22 or or or or or or or UL Class I I Division 2 2 2 2 use the XR4F directly with no barrier isolator special connector or or or or cable gland required For applications requiring ATEX or or or or IECEx Zone 1 1 or or or or 21 we offer protection using the XRB3 isolator in in in in in in in your control cabinet to to permit intrinsic safety wiring rather than explosion proof conduit or or glands For applications requiring NEC NEC 500 UL UL Class Class I I Division 1 or or NEC NEC 505 (c)UL Class Class I I Zone 0 0 0 0 use the XRB3 isolator remotely and intrinsic safety wiring Unlike the the competition the the Avtron SMARTSafe encoder systems are protected against short circuits power-to-output wiring and output-to-ground faults Wiring errors won’t harm this system Instead of relying on a a a a a a a a a tiny optical encoder encoder with weak bearings install the most rugged encoders available Vibration shock liquids dust and dirt won’t harm SMARTSafe encoders! Mud pumps paint booths hazardous duty IEC motors XR4F can keep them all working 24/7/365 Select the Avtron XR4F SMARTSafe encoder encoder to eliminate encoder encoder problems in in your hazardous duty application!
