Azbil VCX-7000 2-Point Detection Explosion-Proof Switches are compact vertical gas/steam explosion-proof limit switches for outdoor use, with 2-point detection and a pressure-resistant and increased-safety structure, conforming to IEC standards, and usable in a hydrogen gas atmosphere. ATEX (Europe), TIIS (Japan), NEPSI (China), KOSHA (Korea), CNS (Taiwan), IECEx, NK (shipping) certified models available. These switches have a light-weight and robust die-cast cover made of aluminum alloy. A die-cast surface with rust prevention treatment and baked finish offers excellent corrosion resistance and weather resistance. Corrosion-resistant models made of die-cast anti-corrosive aluminum are also available. Center-neutral type and simultaneous operation type models available. With the center-neutral type, a single limit switch can detect two limit points (valve upper and lower limits), since two different internal switches operate depending on the direction of the actuator rotation.
