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

    Physical Features

    • Body material: 300 series stainless steel (locknut included)
    • Encapsulation: hermetically sealed, heli-arc welded construction or epoxy encapsulation
    • Magnet that resists demagnetization
    • Focusing tip (pole piece) which allows greater air gap with no signal loss
    • IR leakage: 100 Mohms @ 100 VDC min.
    • High signal output
    • High Shock and Vibration resistance (MIL-STD-202G METHOD 214A, Test Condition H)

    Interconnection Options

    • Two (2) pin gold plated glass sealed connector (mates with: MS3106-10SL-4S)
    • Pigtail with wires or cable
    • NPT threaded body with wire or cable pigtail for explosion proof environments

    Entity Parameters

      Group IIC:
    • Vmax/Ui = 30 VDC
    • Imax/Ii = 300 mA
    • Pi = 0.75 W
    • Ci/Ci = 0 uF
    • Li/Li = 0 mH

    Approvals

    • Intrinsic safety to CSA (with NRTL/C) for Class I, Groups A, B, C, D; Class II, Groups E, F, G; Class III
    • LCIE to 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

    Ambient Temperature

    • -50°C to 175°C
