The new pressure switches S4412 and S4415 convert vacuum in the range of -0,85 bar to -0,15 bar into an electrical switching signal. The pressure switches, which work with a membrane, are available in a variety of types. Customers can choose between different options for the process connection as well as for the electrical connection. A 1/4" screwed fitting made of zinc-coated steel is standard. A big number of different screw threads and materials - also for the membrane - is available as well. The protection class of the electrical connection for the S4415, which is made with a tab connector, can be increased by using a protection cap, which is available as an option. The S4412 has a 90-degree connector as a standard. Customised versions of the switches are available for example with a ready mounted cabling. The switch can be used in NC, NO or changeover mode. The switching point can be easily adjusted with a screw.
Typical applications of the new switches can be found in construction machinery, utility vehicles, marine or defence applications. The possibility to customise the switches in various ways are extremely valuable especially for OEM customers. The new pressure switches S4412 and S4415 are available in different customised versions.
