Danfoss 031E022066 CS Pressure Switch 4-12 Bar G1/4

The Danfoss 031E022066 is a CS series pressure switch designed for automatic control of air compressors, water boosters, and pressure storage systems. This model features a regulation range of 4-12 bar with TPST contact function and automatic reset, making it ideal for industrial compressed air and water pressure applications.

Key Features:

• Three-pole switch with adjustable differential for precise pressure control
• Manual switch that locks the contact system in open position independently of system pressure
• G1/4 female pressure connection for easy installation
• IP43 enclosure rating for protection against dust and water spray
• Contact rating: 12A at 220-415V AC, 9A at 600V AC
• Mechanical life of 1,000,000 operations
• Operating temperature range: -20 to +70°C

Construction and Operation:

The pressure switch consists of a connector, diaphragm, snap system, main spring, differential spring, and 3-pole contact system. Pressure from the controlled system is led through the connector to the diaphragm, which converts pressure to mechanical movement transferred to the contact system. The adjustable differential allows for customized start and stop pressure settings to match specific application requirements.

This pressure switch is commonly used for compressor control, water pump automation, and pressure boosting systems. The CS series is known for reliability in demanding industrial environments with proven performance in both compressed air and water applications.
