About Electrically operated

An electrically actuated pressure switch reports to the control system that a set pressure has been crossed instead of merely displaying it. The range covers measuring ranges from 1 to 600 bar and works as a normally open (NO) or normally closed (NC) contact depending on version. Pumps, compressors and interlocks can be enabled or shut down on that signal.

What matters when choosing

• Measuring range: the group spans 1 to 600 bar. Put the intended switching point in the middle of the range chosen, not at its top end.
• Function: normally open (NO) or normally closed (NC) decides whether a loss of pressure creates a signal or removes one. In a safety chain that choice matters more than the switching point itself.
• Thread: G 1/8 and G 1/4 male are available. The existing measuring port decides which of the two applies.
• Protection class: IP 65 and IP 67 on the units with an M12x1 plug, IP 40 / IP 65 on the hose connected versions. Damp surroundings and regular wash down are the deciding factor.
• Medium temperature runs from -20 °C to 85 °C depending on type. The figure applies to the medium at the port, the permitted ambient temperature of the housing is listed separately.

Typical applications

• Starting and stopping compressors according to line pressure
• Monitoring inlet pressure on machine tools
• Dry running and minimum pressure protection on pumps
• Pressure monitoring in hydraulic circuits
• Enabling pneumatic clamping devices in general machine building

Housings are made of CrNi steel 304 or of plastic depending on version, and production takes place in Germany and China. The 38 articles differ mainly in measuring range and electrical connection.
