691/682 Series piston pressure switch with adjustment knob

The combined 691/682 series piston pressure switch with adjustment knob comprises two main types: an SPDT silver contact pressure switch that is perfect for high-pressure applications up to 900 bar and a Reed SPST NO sensor that is ideal for lower pressures with a compact design. This makes the series particularly suitable for industrial use. The housings are made of anodized aluminum. This housing guarantees durability and protection against corrosion.

In addition, various seals such as NBR+Teflon offer optimal tightness and a long service life. With a protection rating of IP65 to IP40, a wide range of mounting options (such as piastra manifold and DIN connectors) and extensive electrical properties, these switches meet the stringent requirements of the mechanical engineering, hydraulics, pneumatics and transport sectors.
