3 pin IP67 cable connector

HuaYi-FaDa Technology is a professional domestic enterprise specializing in the R&D and production of waterproof connectors, and a legitimate manufacturer and supplier of IP67 3-pin Waterproof Connectors. We possess an independent production system and a mature product line. Our 3 pin IP67 cable connectors are primarily designed for stable connections in sensors, actuators, fieldbus modules, and industrial controllers. Utilizing an integrated injection-molded structure, they provide stable power and signal transmission capabilities. The products support 2-pin, 3-pin, and 4-pin configurations, and cable types and lengths can be customized to meet customer needs. With their stable performance and reliable protection capabilities, they have gained recognition from customers in various industries both domestically and internationally.

I. Product Positioning and Design Highlights

The 3 pin IP67 cable connector is designed with miniaturization, high stability, and strong environmental adaptability in mind, achieving reliable connection and IP67 protection rating within a compact size.

The product uses gold-plated copper alloy contacts to reduce contact resistance and oxidation issues. Combined with a threaded locking structure, it maintains a stable connection even in industrial environments with vibration, humidity, and dust.

We offer two commonly used wire solutions: PUR and PVC. Both are factory-injection molded, effectively reducing issues such as wire breakage, water damage, and poor contact. Suitable for long-term outdoor and industrial use.

Structure and Material Specifications

1. Housing and Insulation Components: Constructed from high-performance engineering plastics, possessing excellent mechanical strength and weather resistance, capable of withstanding daily impacts, UV aging, and extreme temperature variations. It also meets UL94-V0 flame retardant standards, enhancing safety.

2. Conductive Contacts: The contacts are made of copper alloy with gold plating, reducing contact resistance and improving oxidation and corrosion resistance, resulting in more stable current and signal transmission and reducing equipment failures caused by poor contact.

3. Sealing Structure: Utilizing silicone seals and a threaded locking structure, it achieves an IP67 waterproof and dustproof rating when mated, suitable for rain, humidity, and dusty environments.

Note: The IP67 3-Pin Waterproof Connector is not suitable for prolonged immersion in water.

4. Wire and Molding Process: The product uses integrated cable injection molding, with a wire diameter range of 4.0–6.0mm, making it an ultra-miniature waterproof connector that saves installation space. Wire specifications, length, and connector direction can be adjusted according to customer requirements.
