The item does not include a mechanical stop and requires a 2-mm internal hex key for adjustment. Series F4. Galvanized adjustable pressure switches made of carbon steel. Available for both hydraulic and pneumatic applications, pressure switches provide an electrical signal once the system reaches a selected pressure. The switching pressure can be adjusted for various set points simply by turning a screw in the middle of the pressure switch.

Features and benefits:

• Equipped with a mechanical stop to prevent damage from overpressure
• Can be mounted in any orientation
• Switching frequency: 90 cycles/min
• Long mechanical lifespan (1,000,000 cycles at 70 bar)
• Maximum load: 0.5 A (at 250 V AC)
• Accuracy: 4% of the set pressure
• Fixed hysteresis: 10–25% (depending on version)
• Electrical connection according to DIN 43650

These pressure switches are suitable for a variety of applications, including mechanical engineering, shipbuilding, measurement and control technology, hydraulics and pneumatics, pumps, and compressors.
