Description

Key Advantages

Rapid Bayonet Quick-Lock: The SK20 series utilizes a precision bayonet mechanism that secures with a simple 90-degree turn, offering a faster and more vibration-resistant connection than traditional threaded plugs.
Reliable 25A Power Delivery: Optimized for medium-to-heavy electrical loads, the SK20 2-pin version supports up to 25A, providing a stable and efficient power interface for industrial machinery and LED systems.
Certified IP67 Environmental Sealing: Engineered with high-performance O-rings, this waterproof aviation plug prevents any moisture or dust ingress, maintaining electrical integrity in rainy, humid, or wash-down industrial zones.
Ruggedized Metal Housing: The nickel-plated zinc alloy shell provides exceptional mechanical strength and 360° EMI/RFI shielding, protecting sensitive data signals from electromagnetic interference in complex factory environments.
High-Temperature PPS Insulator: Featuring PPS thermoplastic inserts (rated for 260°C), our SK20 ensures superior dielectric strength and prevents deformation during precision soldering or extreme temperature fluctuations.
