Intrinsically Safe Variable Reluctance Sensors
Certified to ATEX, IECEx, and CSA

Intrinsic safety has become an increasingly popular approach for handling sensing requirements in hazardous locations. These sensors are intrinsically safe versions of Motion Sensors (MSI) Hermetically Sealed VR Sensors or Epoxy Encapsulated VR Sensors.

These sensors are certified intrinsically safe to:

CSA (with NRTL/C) for:
Class I, Groups A, B, C, D; Class II, Groups E, F, G; Class III

ATEX (2014/34/EU) for Ex II 1 G; Ex ia IIC or IIB T6 to T3 Ga

IECEx for Ex ia IIC or IIB T6 to T3 Ga

EC Declaration of Conformity and Installation Instructions
ATEX Certification
IECEx Certification
CSA Certification

Type

Variable reluctance (VR) or inductive type

Warranty

Unconditional one (1) year warranty if used within specifications
