Danfoss KPS43 Pressure Switch is a pressure switch that is designed to withstand the harsh conditions of industrial and commercial environments. It is IP67-rated, meaning that it is dust-tight and water-resistant. The KPS43 has a maximum working pressure of 120 bar. This KPS43 Pressure Switch uses a diaphragm-type pressure sensing element. The diaphragm is deflected by the pressure of the medium being measured, which causes an electrical contact to open or close. The KPS43 has a single-pole double-throw (SPDT) electrical contact arrangement, which means that it can be used to control a single electrical circuit.

Features of Danfoss KPS43 Pressure Switch:

  • Wide operating pressure range: 1 to 10 bar
  • High accuracy and repeatability: ± 0.5%
  • Low hysteresis: ± 0.2%
  • IP67 rated for water and dust protection
  • Resistant to vibration and shock
  • Durable construction
  • Easy to install and use
