Product Details

IMI Norgren Pressure Switch

The IMI Norgren 18D series pressure switch has an operating pressure ranges between 1bar and 16bar. This is a vacuum pressure switch with a G1/4 thread connection. This electro-mechanical pressure switch is used for connecting and disconnecting electronic circuits utilizing pressure. It monitors minimum pressure and is equipped with automatic switch off and pressure limit warning. This switch is suitable for use in pneumatic, hydraulic and vacuum systems.

Pressure switches
Pressure switches allow microswitch operation once a pre-set pressure is reached. K and K3 series incorporate a mechanical stop providing over-pressure protection for the spring and microswitch. Electrical connections for all the models to DIN 43650.
Observe the switching range. Do not subject the switch to maximum allowable pressure during normal operation. Short pressure peaks must not exceed this value.
