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.
The VCX-7000 series are gas/steam explosion proof vertical limit switches for outdoor use with 2-point detection and a pressure resistant and increased safety explosion proof structure, conforming to IEC standards, and usable in hydrogen gas atmospheres. The die cast surface with rust prevention treatment and baked finish offers excellent corrosion and weather resistance. Various actuators are available with either center neutral or simultaneous operation configurations. External standards include TIIS, NEPSI, KOSHA, CNS, ATEX, IECEx, and NK chosen by model number.
