Block pressure switches

From vacuum to high pressure: With the block pressure switch from HERION & RAU, you can set the switch point infinitely and with maximum precision via the adjustment knob. The high-quality die-cast zinc housing demonstrates its strengths over conventional aluminum, offering greater stability, higher corrosion resistance, and a better price-performance ratio. With numerous connection and configuration options, you can tailor it to your requirements, whether in hydraulics, mechanical engineering, commercial vehicles, or demanding fluid power systems.
