XR45 (SMARTSafe™) Encoder

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

For Level 2 applications requiring ATEX/IECEx Zone 2 or 22 or UL Class I, Division 2, Groups A,B,C,D use the XR45 directly in your application, with no barrier, isolator or cable gland required.

For Level 1 applications requiring ATEX/IECEx Zone 1 or 21 add the XRB1 or XRB2 isolator; XRB2 isolator systems enable use in Class I, Div 1 and Class I, Zone 0 applications. This permits the use of intrinsically safe wiring instead of explosion proof conduit or glands.

Unlike the competition, the Avtron SMARTSafe encoder systems are protected against short circuits, power-to-output wiring, and output-to-ground faults.

Instead of relying on a tiny optical encoder with weak bearings install the most rugged encoders available for your drilling or industrial applications.  Vibration, shock, liquids, dust and dirt won't harm SMARTSafe encoders!  Paint booths, draw works, coil tubing rigs...XR45 can keep them all working 24-7-365.

Select the Avtron XR45 SMARTSafe™ encoder to eliminate encoder problems in your hazardous duty application!
