Description

These high-quality pressure switches have been developed especially for safety-critical applications. The high quality of the products and manufacturing in accordance with ISO 9001 ensure reliable monitoring of your plant. In production, the switches are traced by quality assurance software at every step and subsequently are 100 % tested.

In order to ensure as flexible operation as possible, the absolute pressure switches are fitted with micro switches, which enable the switching of an electrical load of up to AC 250 V, 20 A directly.

Special features

  • No power supply needed for switching of electrical loads
  • Robust switch enclosure from stainless steel 316L, IP66, NEMA 4X
  • Setting ranges from 0 ... 25 mbar abs. up to 0 ... 1.5 bar abs.
  • Intrinsic safety Ex ia available
  • 1 or 2 independent set points, SPDT or DPDT, high switching power up to AC 250 V, 20 A
