Outline Drawing
XR4F solid shaft encoders are a unique industry first.  By combining Avtron durable magnetic encoder technology with SMARTSafe™ systems, Avtron has created a truly durable solid shaft encoder which can be used in hazardous environments and applications.  It is ATEX, IECEx & cULus certified.  SMARTSafe encoders can be used in gas and ATEX dust hazard environments.  Also available:  hollow shaft models (XR47, XR45, XR685), NEMA style shafted model (XR485), and no-bearing modular encoders (XR56, XR67, XR85, XR115, XR125, XR850).

For Level 2 applications requiring ATEX or IECEx Zone 2 or 22 or UL Class I, Division 2 use the XR4F directly with no barrier, isolator, special connector or cable gland required.

For Level 1 applications requiring ATEX or IECEx Zone 1 or 21, we offer protection using the XRB1 or XRB2 isolator in your control cabinet to permit intrinsic safety wiring rather than explosion proof conduit or glands.  For Level 1 applications requiring NEC 500 UL Class I, Division 1, or NEC 505 (c)UL Class I, Zone 0, use the XRB2 isolator remotely and intrinsic safety wiring.

Unlike the competition, 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 tiny optical 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 to eliminate encoder problems in your hazardous duty application!
