XP5 Magnetic Encoder

XP5 SMARTSafe™ sensors power the world's first explosion-proof encoder with removable electronics and no external barrier!

They are cULus, ATEX, AEx & IECEx certified and offer incredibly reliable no-bearing construction! SMARTSafe XP5 sensors can be used in ATEX/IECEx, cUL, AEX, and UL gas hazardous environments. For Level 1 applications requiring ATEX/IECEx Zone 1 or cULus Class I, Division 1, Groups C & D use the XP5 directly in your application with no barrier or isolator required.

Unlike the competition, Avtron SMARTSafe encoder systems are protected against short circuits, power-to-output wiring, and output-to-ground faults. XP5 features full diagnostics:  it's easy to determine that signal quality is good, and that there are no wiring short-circuits.

Instead of mounting a tiny optical encoder with weak bearings on a wobbling stub shaft mount XP5 directly on your machine and install the rotor on your main application shaft.  Top drives, draw works, coil tubing, paint lines...so many applications benefit from a more reliable no-bearing encoder.  Vibration, shock, liquids, dust and dirt won't harm SMARTSafe XP5 encoders!  

Eliminate the biggest cause of hazardous duty encoder failure--eliminate the bearings with XP5 hazardous duty encoder sensors.
