This is a micro vacuum switch with a waterproof terminal block equivalent to IP54. 【Features】 ■ Equipped with a single-pole double-throw contact, it provides two control signals for ON-OFF at both the upper and lower limits of the set pressure, allowing for changes in the set vacuum level as needed. ■ Waterproof design (equivalent to IP54) using a robust zinc alloy die-cast cover. ■ The pressure detection element uses a highly sensitive rubber diaphragm, capable of detecting minute vacuum levels from -0.2 kPa. ■ The electrical switching mechanism ensures reliability of opening and closing through a sensitive snap-action mechanism, and due to its simple design with minimal cumulative error, it is an extremely high-sensitivity structure, making it optimal as a detection end for vacuum control requiring high precision and long lifespan. ■ Fluids: air, gas, oil, water, etc. (For corrosive liquids, gases, etc., a corrosion-resistant stainless steel pressure receiving part (contact part) is available.) *For more details, please contact us or download the catalog.

This is a waterproof vacuum switch using a robust aluminum die-cast cover. 【Features】 ■ Provides ON-OFF two-point control signals Can change the set vacuum level as needed ■ Uses multi-stage bellows for vacuum detection elements ■ The electrical switching mechanism ensures reliability of opening and closing through a sensitive snap-action mechanism ■ Simple design with minimal cumulative error, resulting in extremely high operational sensitivity ■ Optimal as a detection terminal for vacuum control requiring high precision and long lifespan ■ Fluids: air, gas, oil, water, and others *For details, please contact us or download the catalog.

This is an optimal vacuum switch for setting differential pressure (the difference between ON and OFF). 【Features】 ■ Equipped with a single-pole double-throw contact, it provides simultaneous ON-OFF control signals at both the upper and lower limits of the set vacuum level, allowing for adjustments to the set vacuum level as needed. ■ Uses multi-stage bellows as the vacuum detection element. ■ The electrical opening and closing mechanism ensures reliability through a sensitive snap-action mechanism. ■ With a simple design that minimizes cumulative errors, it features a highly sensitive structure, making it ideal as a detection endpoint for vacuum control that requires high precision and long lifespan. ■ Fluids: air, gas, oil, water, etc. For corrosive liquids and gases, a corrosion-resistant stainless steel pressure part (contact part) is available. *For more details, please contact us or download the catalog.
