Dual Winding VR Sensors

This product family offers Variable Reluctance (VR) speed sensors that integrate dual windings within the sensor housing to provide redundant output capability, and are extremely popular in aerospace and other critical applications. Standard models incorporate stainless steel housings, MIL spec connectors or cabling, and grounding to case to enhance protection against EMI and external noise. This line of sensors also offers a wide temperature range and is suitable for use in cryogenic environments.


  • Variable reluctance (VR), dual winding

Physical Features

  • Body material: 300 series stainless steel (locknut included)
  • Encapsulation: hermetically sealed, heli-arc welded construction or epoxy encapsulation
  • Magnet that resists demagnetization
