What is a waterproof wire harness?

Waterproof wiring harness is an electrical connection component designed for wet, underwater or groundwater environments. Its core function is to achieve waterproof, waterproof and corrosion resistance through special structure and materials.

The waterproof wire harness is waterproof mainly due to the waterproof function of the connector on the wire harness, and the connector is divided into several types.

Circular waterproof connector ‌M series‌: such as M8 and M12 specifications, suitable for sensors and industrial automation equipment, with IP68 protection through rubber rings and thread locking, supporting 2-8 core signal transmission.

The circular waterproof connector is integrated by injection molding to avoid water seepage between the cable and the connector. It is commonly used in underwater robots and outdoor equipment.

Rectangular waterproof connector DEUTSCH DT series: such as DT04-2P, DT06-2S, with metal shell and snap-on seal design.

DT series waterproof connectors are mostly used for power and signal connections in engineering vehicles and new energy equipment.

MC4 photovoltaic connector: specially designed for solar equipment, easy to plug and unplug, with built-in sealing ring, resistant to 30A current and outdoor UV environment.

M12 flange connector: A flange connector is a device used to connect two or more components. It is usually composed of a flange, a gasket, and bolts. It supports front/rear installation and is equipped with an injection molded housing to achieve IP67 protection.

Flange connectors are suitable for industrial control cabinets and sensor fixed wiring.

Network waterproof connector dual-port protection type: The spring clamping structure and split shell shield the interface to reduce the risk of short circuit of RJ45 network cable in humid environment.

The connectors of waterproof harnesses are mostly made of nylon, metal or flame-retardant rubber, with polyurethane glue or silicone sealant inside. The mainstream products reach IP67/IP68 and can withstand immersion in 1 meter of water and high-pressure washing. Its certification standards include UL20549, UL2517, etc., to ensure electrical safety and durability.
