M12 Pressure Switch, Fail-Safe – 0422


■ M 12×1 DIN EN 61076-2-101-A (PIN 1+3)
■ Burst pressure safety: Up to 5,800 psi (400 bar)
■ Overpressure safety: Up to 4,350 psi (300 bar)



M12 Pressure Switch Performance:

  • Zinc plated steel
  • Overpressure safety: Up to 4,350 psi (300 bar)
  • Up to 42V with supplementary functions
  • Operating current: ≤ 30 mA
  • Seal material: NBR (Buna N), EPDM, FKM (Viton®), FFKM, HNBR
  • NAMUR Diagnostic function (fail-safe) with short-circuit and cable break detection


Has the advantages of a pressure switch but works like a Pressure Transducer with mA output. The value of mA output will change when the contact of the switch opens or closes. The value of the mA output is determined by the supply voltage and the resistors selected.

  • Up to 1,000 x Overpressure
  • No EMI issue
  • Recognizes line break
  • Recognizes short-circuit
  • No external excitation required
  • Field or factory adjustable

A wide-range of plug-in types, supplementary functions, seal materials, and accessories are available.
