The F4 series does not include a mechanical stop and requires a 2-mm internal hex key for adjustment. Zinc-plated adjustable pressure switches made of carbon steel from RS. Available for both hydraulic and pneumatic applications, pressure switches provide an electrical signal as soon as the system reaches a selected pressure. The switching pressure can be adjusted for different set points by simply turning a screw in the center 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 (10^6 cycles at 70 bar)
• 0.5 A maximum load (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 wide range of applications, including mechanical engineering, shipbuilding, measurement and control technology, hydraulics and pneumatics, pumps, and compressors.
