Product Description
The 4 pole waterproof connector is a multi-circuit sealed connector designed for outdoor and industrial equipment that requires reliable power and signal connection in one compact interface. This product corresponds to the M15 4-pin waterproof connector structure, which is suitable for systems beyond simple two-wire power. With four poles, the connector can support multiple circuits, control signals, or power-plus-signal layouts. For buyers serving smart lighting, solar street lights, underground projects, or equipment manufacturers, the 4 pole waterproof connector provides a practical balance between circuit capacity, waterproof protection, and installation convenience.
We manufacture the 4 pole waterproof connector with a PA66 nylon shell, gold-plated brass contacts, welding assembly structure, and IP68 waterproof level. Its design is suitable for equipment exposed to rain, moisture, vibration, and outdoor temperature changes. In real outdoor projects, the connector must do more than fit the cable; it must protect the electrical interface after months or years of use. Our 4 pole waterproof connector is built to maintain stable conductivity and sealed connection in demanding environments. With a 250V operating voltage, 2A-10A current rating, and 1500 mating cycles, it gives project buyers a durable connector for lighting, control, and outdoor equipment integration.

Application Areas
Smart Street Lighting
Suitable for solar street lights, dimming systems, public lighting, and outdoor fixtures that need both power and control wiring.
Outdoor Electrical Projects
Used in underground cable systems, landscape lighting, fountain lighting, and outdoor control devices requiring waterproof multi-circuit connection.
Industrial and Mechanical Equipment
Can be applied to industrial equipment, compact control units, and field wiring where reliable sealed connection is required.
Factory Strength
Our factory has experience serving connector-related manufacturing and has built production capability around precision molds, injection molding, stamping, assembly, and testing. This makes us suitable for buyers who need stable connector supply rather than unstable mixed-source products.
Customization Service
The 4 pole waterproof connector can be customized for cable length, cable specification, wiring definition, color, and mating structure. We can support drawings or samples when customers need connector solutions for a specific lighting fixture or equipment housing.
Quality Control
We focus on shell material, contact plating, contact resistance, mating life, and waterproof sealing. For 4-pole products, we also pay attention to pin position and circuit stability, because multi-circuit connectors require higher consistency than basic two-wire connectors.
