Mini Pressure Switch - PXA

Brand: WIKA Alexander Wiegand SE & Co. KG
Request Information
These high-quality mechanical pressure switches have been developed especially for safety-critical applications. The great advantage of mechanical pressure switches is that no supply voltage is required for the switching process.
Features
  • No power supply needed for switching of electrical loads. 
  • Robust switch enclosure from stainless steel 316, IP66, NEMA 4X. 
  • Setting ranges from 1 ... 2.5 bar to 200 ... 1,000 bar. 
  • Repeatability of the set point ≤ 1 % of end of setting range. 
  • 1 set point, SPDT or DPDT, high switching power up to AC 250 V, 5 A.
