Limit Switches


(Refer to the product lineup page.)

We offer an extensive lineup of limit switches that can be installed and used in many different environments. These switches are widely used in general industrial machinery, various industrial plants, outdoor equipment, and designated explosion-proof equipment.
Select the optimal limit switch for your application and installation environment. Models designed for high-temperature environments, low-temperature environments, and marine/salt environments are available, among others.
Actuators and products with various operating characteristics, environmental resistances, operation indicators, and explosion-proof certifications are also available.

Robust and reliable

Rugged die-cast aluminum case contains a two-circuit dual cutoff switch. This product is hard to break and provides sure shutoff of circuits.

Excellent resistance to harsh environments

In addition to general-purpose and explosion-proof models, the available types include cold-resistant models, heat-resistant models, corrosion-resistant models, and weather-resistant models.

Extremely long service life

Through reduction of friction in the sliding part of the switch and improved corrosion resistance, the mechanical service life of these products (30 million mechanical operations or more) is over three times that of the conventional service life in the field, significantly reducing equipment downtime.


Models designed to prevent sticking of welding spatter are available.

Explosion-proof models

Gas/vapor explosion-proof and enhanced-safety explosion-proof models conforming to IEC explosion-proof standards are available. Their explosion-proof structure (Exde II C T6) enables them to be used in a hydrogen gas atmosphere. Available explosion-proof certifications include those from TIIS, NEPSI, KOSHA, CNS, ATEX, IECEx, and NK.

All-SUS limit switches

All externally exposed parts are stainless steel, making these products fully resistant to corrosion. The switches can be used safely even in severe conditions such as harbor facilities, pharmaceutical facilities, and water-treatment plants (in water as much as 10 meters deep).
