Limit Switches


  • 2 Point Detection Limit Switches

    Azbil VCL-□□ Waterproof Vertical Limit Switches 2 sets of SPDT built-in switches enable use as a 2-point detection (center neutral)or multi-circuit control switch depending on the model. The limit switches have high sensitivity (pretravel=10°, movement differential=3°).


  • Compact Horizontal Limit Switch Form Factor

    Azbil SL1-□□ series of General Purpose Compact Horizontal Limit Switches offers a robust long-life and maintenance-free design with a mechanical life of 20 million operations, owing to a 2 piece-spring mechanism. These maintenance-free switches have a superior seal: oil-resistant/immersion-proof type (JIS) and IP67 (IEC). O-ring and integral diaphragm seal are built-in. The small, space-saving body can be tightly gang-mounted and have high sensitivity (movement differential = 0.1 mm). Contact form sing-pole double-throw (SPDT). Contact type- standard load type: pure silver rivet, low current load type: gold-plate rivet, M3 screw terminal, UL/CSA/GB (CCC marking) certified models available. Rugged models also available.

    As part of the Azbil SL1-□□ series of limit switches, the SL1-□C General Purpose Compact Horizonal Limit Switches (Rugged) models offers potted switches that protect the conduit and terminals that are coolant resistant. The C-spring material is high-cobalt alloy, which enhances resistance to coolants. The shape of the diaphragm seals has been modified to prevent cracking and degradation of insulation (standard type). The internal plunger with a molded-in diaphragm seal prevents coolant from entering inside. This series offers potted switches that protect the conduit and terminals.”


  • Explosion Proof Limit Switches

    Azbil 1LX8000 Heat/Cold resistant Vertical Explosion-Proof Limit Switches are compact vertical 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.

    Azbil LX7000 Vertical Explosion-Proof Limit Switches are compact vertical 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 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. 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 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.


  • Positive Opening Mechanism Limit Switch

    Azbil LJA10 Snap Action Limit Switches with Positive Opening Mechanism enable general industrial machines to comply with EC directives, acquire CE markings and help in acquisition of EN approval. Limit Switches conform to EN 50041 standard. The LJA10 have N/C//N.O. electricity independent contacts (Zb). Use of twin-contact structure improves contact reliability. Mounting centers dimensions are compatible with most of the LS general purpose limit switches. High degree of sealing meets immersion proof (JIS)and IP67 (IEC 60529) standards. UL, CSA, TUV, and CQC certified.
