    The plastic waterproof electrical junction box IP68 is made of ABS plastic, PC or other plastic, which has the characteristics of dustproof, waterproof, anti-corrosion, insulation and shockproof.

    Top cover fixing screws are designed to prevent screws from falling and losing, multiple internal mounting points provide maximum ease of installation for rails, PCBs, power modules and expansion cards.

    Some models choose transparent top cover from PC. Various sizes and specifications can provide solutions for petrochemical plants, docks, sewage treatment plants, electroplating plants, gardens, residential lighting, rail transport, etc.

    Die-cast aluminum waterproof electrical junction box is formed by die-casting of silicon aluminum alloy.

    The use of spray surface treatment technology makes the die-cast aluminum waterproof box resistant to the environment.

    Due to the characteristics of the metal itself, compared with similar plastic junction boxes, die-cast aluminum junction boxes also have the characteristics of heat dissipation, anti-static and fire resistance.

    The working temperature of -40 ° to 120 ° can better adapt to the high temperature and low temperature environment the equipment is in.

    Most of the products are equipped with metal hanging feet to facilitate fixing the equipment to the wall.

    The mounting boss at the bottom is pre-threaded for component mounting. Internal attachment points can also be used to ground the electrical enclosure.
