Limit Switches

A wide selection Azbil limit switches are available for installation in highly diverse rugged environments (e.g., in a hydrogen gas atmosphere, outdoors, and underwater). Models are available that are spatter-guarded, high-temperature, low-temperature, explosion-proof, and safe for marine/salt environments, among others depending on the model. Our limit switches are widely used in general industrial machinery, various industrial plants, outdoor equipment, and designated explosion-proof equipment. They have sealed-in internal switches that ensure high sealing performance and a robust structure. Select the optimal limit switch for your application and installation environment.


  • Explosion-Proof Limit Switches

    Azbil Model _LX7000_ Vertical Explosion-Proof Limit Switches are compact gas/vapor explosion-proof switches for outdoor use, with a pressure-resistant and increased-safety explosion-proof 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 are 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 a baked finish offers excellent corrosion resistance and weather resistance. Corrosion-resistant models made of die-cast anti-corrosive aluminum are also available. _LX7000_ switches are compatible with various actuator head shapes, including roller lever, adjustable roller lever, plunger, roller plunger, fork lever, and non-directional operation types.

    Azbil Model VCX-7_0_ 2-Point Detection Explosion-Proof Switches are compact vertical gas/steam explosion-proof limit switches for outdoor use, with 2-point detection and 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 are 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 a 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 are 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.


  • General Purpose Limit Switches

    Azbil General Purpose Limit Switch Models _ LS _ _ with rugged construction are available in an extensive range of models for use in a wide range of applications and environments in general industrial machinery, various industrial plants, outdoor equipment, and designated explosion-proof equipment. You can select the optimal limit switch for your application and installation environment. Models are available for high-temperature, low-temperature, and marine/salt environments, among others.

    Actuators and products with various operating characteristics, environmental resistances, operation indicators, and explosion-proof certifications are also available.


  • Limit Switches with Positive Opening Mechanisms

    Azbil offers a range of limit switches with positive opening mechanisms, including snap action standard, compact plastic, and compact die-cast switches. Switches are UL, CSA, TUV, and CQC certified, depending on the model.
