Key Advantages

1. Superior Waterproof Protection (IP67/IP68)

The SL Series offers complete dustproofing and can operate reliably even when submerged in water for extended periods.

2. Quick Plug & Disconnect

The press-lock structure allows for easy, single-handed operation.
Ideal for fast on-site installation or disassembly, improving efficiency in demanding field applications.

3. Excellent Electrical Performance

Gold-plated contacts significantly enhance conductivity, durability, and corrosion resistance.
The plating protects against oxidation and environmental corrosion — ideal for challenging conditions such as acid rain or corrosive outdoor environments — ensuring long service life.

4. Reinforced Engineering Plastics

Built with UL94-V0 flame-retardant material, the housing provides:

High strength & wear resistance
Excellent heat and chemical resistance
Outstanding electrical insulation performance
