Explosion-Proof Limit Switch VPV-4B12 for Remote Control Applications

Track switches explosion-proof are designed for remote control electric drives of machines and mechanisms in stationary installations and on mobile vehicles. installations and on mobile means of land, sea and sea transport, where they are actuated by electric drives of machines and mechanisms. where they are actuated by control stops, as well as for signalling associated with the said electric drives or other electrotechnical devices.

Application: switches are designed for operation both in coal and oil shale mines, dangerous by gas and dust, and in underground workings of coal mines and mines, including dangerous by gas and coal dust, as well as in their above-ground structures, in explosive zones of industries, means of transport and storage of products of chemical, oil-refining, gas and other industries. VPV-4B consists of a cover and a body: made of AL-2 alloy GOST 1583-89 VPV-4B by the number of contacts has 2P+2Z. With a drive (lever with a roller).VPV-4B is completed with two input devices for bringing flexible or armoured cable with an outer diameter from 12 to 20mm.
