■ Overpressure safety: Up to 4,350 psi (300 bar)
■ Field-adustable pressure range: 1.45 to 2,175 psi
■ Zinc-plated steel body



0412 AMP Superseal Pressure Switch Performance:

  • AMP Superseal 1.5® Connector
  • Field-adjustable pressure range: 1.45…2,175 psi
  • Overpressure safety: Up to 4,350 psi (300 bar)
  • Burst pressure safety: Up to 5,800 psi (400 bar)
  • Zinc-plated steel body, HEX 24mm (0.95″)
  • Max. working voltage: 8.2 VDC…30 VDC
  • Operating current: ≤ 30 mA
  • Withstands high-pressure wash and immersion (IP67)
  • Seal material: NBR (Buna N), EPDM, FKM (Viton®), 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.
