XR4F

Protected Against Surges and Wiring Problems

The XR4F solid shaft encoders are a unique industry first, combining durable magnetic encoder technology with SMARTSafe™ systems to create a truly robust solution for hazardous environments and applications. These encoders are ATEX, IECEx, and cULus certified, making them suitable for use in gas and ATEX dust hazard environments. We also offer hollow shaft models (XR45, XR685), NEMA style shafted models (XR485), and no-bearing modular encoders (XR56, XR85, XR115, XR125, XR850).

For applications requiring ATEX or IECEx Zone 2 or 22, or UL Class I, Division 2, the XR4F can be used directly without the need for barriers, isolators, special connectors, or cable glands.

For applications requiring ATEX or IECEx Zone 1 or 21, we provide protection using the XRB3 isolator in your control cabinet, allowing for intrinsic safety wiring instead of explosion-proof conduit or glands. For applications requiring NEC 500 UL Class I, Division 1, or NEC 505 (c)UL Class I, Zone 0, the XRB3 isolator can be used remotely with intrinsic safety wiring.

Our SMARTSafe encoder systems are protected against short circuits, power-to-output wiring, and output-to-ground faults, ensuring that wiring errors won’t harm the system.

Unlike traditional optical encoders with weak bearings, our rugged SMARTSafe encoders are built to withstand vibration, shock, liquids, dust, and dirt. Whether it’s mud pumps, paint booths, or hazardous duty IEC motors, the XR4F can keep them all working reliably 24/7/365.

Choose the XR4F SMARTSafe encoder to eliminate encoder problems in your hazardous duty applications!
