Pressure Switch 30 A/F
Reliable pressure switches with changeover contacts, aluminum housing, and precise pressure adjustment.
The Suco 30 A/F mechanical pressure switch is a universal pressure control device for liquids, gases, and air. It is equipped with a microswitch with a changeover contact, an aluminum housing, and the ability to finely adjust the operating point.
The Suco 30 A/F pressure switch is a reliable pressure control solution that uses a toggle microswitch with silver-plated contacts. Thanks to its robust aluminum housing, extended adjustment ranges, and ability to work with different media.
Key Features
Variety of designs: diaphragm and piston versions available for different operating conditions.
Contact types: normally open (NO) or normally closed (NC) — for flexible system configuration.
Precise adjustment: easy adjustment of the operating point, factory calibration possible. Adjustable hysteresis: 10-30%.
Versatile application: suitable for liquids, gases, air, and water.
Contact protection: special covers prevent dust and moisture from entering.
Operational stability: high accuracy and reliability even after prolonged use.
Compliance with standards: full RoHS II compliance — a guarantee of environmental safety.
