Description

These high-quality pressure switches have been developed especially for safety-critical applications. The high quality of the products and manufacturing in accordance with ISO 9001 ensure reliable monitoring of your plant. In production, the switches are traced by quality assurance software at every step and subsequently are 100 % tested.

In order to ensure as flexible operation as possible, the pressure switches are fitted with micro switches, which enable the switching of an electrical load of up to AC 250 V, 20 A directly.

For lower switching power ratings, such as for PLC applications, argon gas-filled micro switches with gold-plated contacts can be selected.

Special features

No power supply needed for switching of electrical loads
Robust switch enclosure from aluminium alloy or stainless steel 316L, IP66, NEMA 4X
Setting ranges from 0 ... 160 mbar to 0 ... 40 bar with high static and high one-sided pressure up to 250 bar
Intrinsic safety Ex ia available
1 set point, SPDT or DPDT, high switching power up to AC 250 V, 15 A
