The Whitman Controls P605L NEMA 4 High Pressure High Set Point High Accuracy Pressure Switches are a line of severe application controls that can withstand massive pressure spikes from hydraulic systems. These switches can see pressure spikes to 9,000 psig without comprising switch integrity or functionality. They also afford the end user higher set points to complement more severe environments and low set point repeatabil¬ity. The P605L is the NEMA 4 rated weather-proof, liquid-resistant version of the P605, suitable for outside applications or in areas of condensing humidity. The P605L switches feature adjustable Military or DIN electri¬cal connectors plus numerous fitting options to meet any custom design.
