Description

BARTEC miniature switches are used in areas with of limited space for a flameproof switching element. They are especially suitable for applications in valves, thermostats, push switches, servo components, level metres and switching gears. The smallest Ex d miniature switch in the world is encapsulated in a plastic enclosure. The leads or cable tail are potted in at the base. The standard version of the BARTEC miniature switches contains fine silver contacts. Other contact materials such as gold plated silver or solid gold are available for low currents and voltages.

The insert switch with wires is available as a building block for your explosion-proofing solution. These insert switches are tested and approved by PTB (the Federal Physical-Technical Institute) according to Ex Guideline 94/9/EC. After installation, the complete device is tested by an authorized institution. Thanks to its PTB approval, the microswitch itself needs not be individually tested. The leads are individually marked. The length of the cable is 50 cm (standard). Other lengths can be supplied on request. For the connection of the cores we recommend our BARTEC Ex Mini-terminals.
