Product Description
Product Overview
Designed for rigorous industrial environments, this 2-Pin Waterproof Circular Connector represents the pinnacle of Plastic Injection Molding precision. Engineered by Sunmy Hardware to meet strict IP67 standards, this connector ensures reliable power and signal transmission in harsh conditions. Featuring a robust Nylon housing and gold-plated brass contacts, it offers superior resistance to corrosion, vibration, and moisture. This is an ideal solution for outdoor lighting, industrial automation, and heavy machinery applications where durability is non-negotiable.
Manufacturing Process & Engineering Insight
At Shenzhen Sunmy Hardware, we leverage advanced manufacturing capabilities to produce high-performance interconnect solutions.
Precision Plastic Injection Molding
The connector shell is manufactured using high-grade Nylon (PA66/Engineering Plastic) via high-precision injection molding machines. This ensures high structural integrity, consistent wall thickness, and zero flash, resulting in a perfectly threaded locking mechanism.
Material Science
We utilize specialized mold flow analysis to ensure the Nylon material maintains its mechanical strength and thermal stability across a wide temperature range (-20°C to 85°C).
Contact Assembly
The brass pins are precision-turned and gold-plated to minimize contact resistance (Max 10mΩ) before being securely seated within the molded housing, ensuring they remain fixed even during high-cycle mating.

Technical FAQ
A1: Yes. As a direct manufacturer with in-house injection molding capabilities, we offer OEM/ODM services. We can customize the cable assembly length, change the shell material (e.g., to fire-retardant UL94-V0), or modify the color based on your MOQ requirements.
A2: Our quality control process includes rigorous air-tightness testing and immersion testing on batch samples to verify the sealing integrity of the injection-molded shell and internal O-rings.
A3: For standard models like the WP-02F1, lead times are typically 7-15 days. For custom injection-molded solutions, lead times may vary depending on mold development and tooling requirements.
A4: The rear of the pins is designed for solder bucket termination, allowing for a secure and permanent wire connection before the over-molding process or final assembly.

Frequently Asked Questions
IP67 means the connector is completely dust-tight (6 — no ingress of dust) and can withstand immersion in water up to 1 meter deep for 30 minutes (7). This makes it ideal for outdoor lighting, marine equipment, and industrial environments exposed to rain, humidity, or wash-down conditions.
The connector is rated for a maximum current of 5A and a rated voltage of 250V. It also features a dielectric withstanding voltage of 1.0KV and a contact resistance of no more than 10mΩ, ensuring safe and efficient power or signal transmission in demanding applications.
The connector shell is manufactured from high-quality Nylon (PA66 Engineering Plastic) using precision injection molding, offering excellent mechanical strength and thermal stability from -20°C to 85°C. The contacts are made from brass with gold or nickel plating to minimize oxidation and ensure long-term conductivity.
Yes. The combination of an IP67-rated Nylon housing, gold-plated brass contacts, and a threaded locking mechanism makes this connector highly suitable for outdoor lighting systems, industrial automation equipment, and heavy machinery where resistance to vibration, moisture, and corrosion is critical.
Absolutely. Sunmy Hardware operates its own in-house injection molding facility and offers full OEM/ODM customization. Options include custom cable lengths, alternative shell materials (such as fire-retardant UL94-V0 nylon), color modifications, and UV-resistant additive formulations — all subject to minimum order quantity (MOQ) requirements.
Sunmy Hardware employs a multi-stage quality control process that includes mold flow analysis during design, dimensional inspection of injection-molded shells, air-tightness testing, water immersion testing for IP67 verification, and electrical performance testing of contact resistance and insulation resistance on every production batch.
