Stainless steel switch enclosure
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, 5 A directly.
For lower switching power ratings, such as for PLC applications, argon gas-filled micro switches with gold-plated contacts can be selected as an option.
For two separate circuits the switches are also available in the version DPDT (double pole double throw).
By using a Belleville spring the simultaneous triggering of the DPDT occurs at either rising or falling pressure. Moreover the snap-acting behaviour of the Belleville spring increases stability and vibration resistance.
All wetted materials are from stainless steel as a standard. For applications with special requirements on the wetted parts, versions with materials from Hastelloy are available.
