Understanding the Functions of a Limit Switch

07 Apr.,2023

 

Features of the Azbil switches include:

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 the 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.

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).
