High Switching Capacity of 15A And 0.05MM High Precision Limit Switch

Will the internal metal contacts oxidize and cause poor contact after long-term use in a humid environment?

The ESMZ series of high-reliability limit switches feature a high switching capacity of 15A@250VAC, enabling direct operation of large load equipment such as motors. Their ultra-precise action difference of 0.05mm ensures accurate detection of mechanical displacement. Combined with a 500,000-cycle electrical lifespan (5×10⁵ operations), it significantly reduces maintenance frequency. The entire series has passed 1000m/s² mechanical shock certification and IP67 protection level, and can withstand extreme vibrations, dust, and humid environments, providing stable position detection solutions for construction machinery, automated production lines, and outdoor equipment.

Completely eliminate the risk of oxidation, with triple protection guarantee:

1. Sealing structure: The switch housing is sealed with both ultrasonic welding and silicone rings (compliant with IP67 waterproof standard), effectively preventing water and moisture from entering.

2. Gold-plated contacts: The core contacts are coated with a 5 μm thick gold layer, with a resistance of less than 15 mΩ and excellent oxidation resistance.

3. Humidity verification: Passed the 85%RH humidity aging test, equivalent to a harsh environment for 5 years of use.
