XR56A

Reliable Performance in Hazardous Environments

The XR56 SMARTSafe™ 4.5″ Magnetic Encoder delivers exceptional reliability in hazardous environments with its modular, no-bearing design. Certified for ATEX and UL applications, it withstands gas and dust exposure while eliminating the need for barriers, isolators, or explosion-proof glands in Level 2 installations.

Whether in paint booths, draw works, or coil tubing rigs, the XR56 ensures continuous operation in the harshest industrial settings. Built to endure vibration, shock, liquids, and contaminants, it outperforms traditional encoders that rely on fragile bearings.

For Level 1 applications, the XR56 integrates with XRB1 or XRB2 isolators, allowing intrinsically safe wiring instead of costly explosion-proof conduit.

Unlike conventional optical encoders, the XR56 mounts directly on your application shaft, providing unmatched durability and fault protection against short circuits and wiring issues. By eliminating bearings—the most common point of failure—the XR56 keeps your critical systems running 24/7 with minimal maintenance.

  • Replaces BEI H38 and Dynapar X25 explosion-proof encoders
  • Eliminates large & costly flange adapters & flowerpots
  • Fits shafts 0.500″ – 3.188″ [10 – 85 mm]
  • Thin profile reduces overall motor depth
  • No air gap adjustment required
  • Shrugs off dirt, oil, and water contamination
  • No glass disks to break or optics to fail
  • 4,500,000+ hour MTBF design
