NNC Waterproof Microswitch NFW8 Series
In industrial automation, outdoor equipment, and humid environment applications, the waterproof performance and reliability of micro switches are critical to the safe operation of entire systems. Traditional micro switches often suffer from moisture erosion, contact oxidation, and short lifespan. The NNC NFW8 Waterproof Micro Switch delivers a perfect solution for harsh environments with military-grade sealing technology and precision structural design, offering three core advantages.
✅ Advantage 1: IP68 Ultra-Strong Waterproof — Fearless in Extreme Environments
The NFW8 adopts a multi-layer sealing structure (silicone seal ring + laser-welded housing), certified with IP68 waterproof rating. It can operate while fully submerged in 1.5 meters of water and withstand high-pressure water jet cleaning. Ideal for outdoor equipment, medical instruments, food machinery, and other humid, dusty, or oily environments.
✅ Advantage 2: High-Precision Contact Structure — Ultra-Long Mechanical Life
Featuring silver alloy contacts and a double-break snap-action mechanism, the contact resistance is <20mΩ with an actuation accuracy error ≤0.1mm. The mechanical lifespan reaches 5 million cycles, and the electrical lifespan achieves 500,000 cycles (under 5A/250VAC load), offering 5 times greater durability than standard micro switches.
✅ Advantage 3: Full Material Corrosion Resistance — Global Safety Certifications
The housing uses 316 stainless steel + engineering plastic composite structure, resistant to acids, alkalis, salt spray, and UV aging. Certified by UL/CE/ROHS, it operates reliably within a temperature range of -40℃ to 125℃, meeting various harsh working condition requirements.
