XR685 SMARTSafe hollow shaft incremental quadrature rotary encoders are a breakthrough in hazardous duty encoders. They are ATEX/IECEx and UL approved and offer huge bearings for maximum life. SMARTSafe encoders can be used in ATEX/IECEx gas and dust and UL gas hazardous environments. Also available: hollow shaft models in other bore sizes (XR45), shafted models (XR4F, XR485), no-bearing modular encoders (XR56, XR85, XR115, XR125, XR850), and modular sensors (XR5, XR12).
For applications requiring ATEX/IECEx Zone 2 or 22 or UL Class I, Division 2, Groups A,B,C,D use the XR685 directly in your application, with no barrier, isolator or cable gland required.
For applications requiring UL Division 1, ATEX/IECEx Zone 1 or 21 use the XRB3 isolator in your control cabinet which permits the use of intrinsically safe wiring instead of explosion proof conduit or glands. XRB3 Isolator Systems enable use in Class I Div 1 and Class I Zone 0 applications.
Unlike the competition, Avtron SMARTSafe encoder systems are fully protected against short circuits, power-to-output wiring, and output-to-ground faults at every point. Wiring errors won't harm this system!
Instead of depending on a tiny optical encoder with weak bearings use XR685. Vibration, shock, liquids, dust and dirt won't harm SMARTSafe XR685 encoders! Paint booths, draw works, coil tubing rigs...XR685 can keep them all working 24/7/365.
Eliminate encoder failures in your hazardous environment application-select XR685 today!
