Danfoss 031E023566 is a CS series pressure switch designed for automatic start and stop control in air compressor and water booster applications. This 3-pole pressure switch features a G 1/2 pressure connection, IP55 enclosure rating and an adjustable stop pressure range of 4 to 12 bar, with an adjustable differential range of 2.0 to 4.0 bar. Built for dependable electromechanical pressure control, it uses a diaphragm-operated snap-action mechanism to convert system pressure into contact movement for switching pumps, compressors or associated control equipment. The unit includes a manual switch for locking the contact system in the open position and is suitable for use with air and water media within the specified operating limits. Its robust construction, adjustable settings and compact self-supporting design make it a practical choice for industrial and commercial pressure regulation systems.

What type of component is this?
It is a Danfoss CS pressure switch for air and water applications. It is designed to automatically start or stop equipment such as compressors, pumps and pressure boosting systems according to the pressure setting.
What pressure range does it cover?
This version is designed for a stop pressure range of 4 to 12 bar, with an adjustable differential range from 1 to 4 bar depending on the setting.
What is the pressure connection size?
The pressure connection is G 1/2, making it suitable for systems that use this common threaded connection standard.
What enclosure rating does it have?
This model has an IP55 enclosure rating when installed in the recommended vertical orientation with the connection facing downwards.
Is it suitable for air compressor control?
Yes. The CS pressure switch range is commonly used for automatic start and stop control of air compressors, including applications where an accessory pressure relief valve may be used.
Can it be used in water booster systems?
Yes. It is suitable for water booster and pump control applications where switching is required based on system pressure.
What contact arrangement does it use?
Danfoss 031E023566 uses a three-pole contact system, also referred to as TPST, which is standard for this version of the CS pressure switch.
What electrical load ratings apply to this pressure switch?
The contact load is rated at 12 A for AC-3 at 220 to 415 V, 9 A for AC-3 at 600 V, and 2 A for DC-13/14 at 220 V when three contacts are connected in series.
What ambient temperature range is it designed for?
The specified ambient temperature range is -20 to 70 °C. For water media, the normal stated medium temperature range is 0 to 70 °C.
How is the start and stop pressure adjusted?
The stop pressure is set using the main pressure screw, while the difference between the start and stop pressures is adjusted using the differential screw.
Does it include a manual switch?
Yes. The CS design includes a manual switch that can lock the contact system in the open position independently of system pressure.
What is the approximate weight?
The approximate weight is 0.5 kg, making it a compact pressure control component for panel or direct connection mounting.
