Product Description

Our 2-pin and 3-pin Waterproof Connectors are engineered for reliability in demanding environments. As a specialist manufacturer, we have designed these connectors to provide a robust, sealed solution for transmitting power and signals. The 2-pin version is primarily used for basic power supply applications, while the 3-pin connector adds a crucial third contact, making it ideal for applications requiring a separate ground wire, a control signal, or a third phase in simple three-wire systems. Constructed from high-quality, engineering-grade materials, these connectors feature an IP68 rating, ensuring complete protection against dust, dirt, and long-term water immersion. They are the ideal electrical interface for outdoor, industrial, and automotive applications where environmental resilience is non-negotiable.

Product Features

Superior Sealing Performance: Achieves an IP68 protection level, guaranteeing performance even when submerged in water up to 1.5 meters deep for extended periods. Advanced silicone rubber sealing rings and a precision-molded interface create an impermeable barrier.

Robust Mechanical Structure: The connector housing is made from high-impact PA66 material with UV resistance, preventing brittleness and cracking from sun exposure or physical impact. The secure screw-locking mechanism prevents accidental disconnection.

Excellent Electrical Properties: High-quality copper contacts with precision plating ensure low contact resistance, minimal voltage drop, and high current-carrying capacity, reducing energy loss and heat generation.

Easy Installation and Maintenance: The user-friendly design allows for quick wire termination and assembly without specialized tools. The clear pin configuration (2-pin/3-pin) prevents mating errors.

Corrosion and Chemical Resistance: The housing and internal components are resistant to corrosion, oils, and common chemicals, ensuring long-term reliability in harsh industrial or marine settings.

Product Advantages

Choosing our waterproof connectors provides distinct benefits that translate directly into project success and cost savings:

Enhanced System Reliability and Uptime: By preventing moisture and contaminant ingress, these connectors drastically reduce the risk of short circuits, corrosion, and system failure. This leads to increased operational uptime and lower maintenance costs for your equipment.

Long-Term Durability in Harsh Conditions: Unlike Standard Connectors, our products are built to withstand extreme temperatures, mechanical stress, and UV radiation. This durability extends the lifecycle of both the connector and the connected equipment, providing a superior return on investment.

Simplified Procurement and Inventory Management: We offer both 2-pin and 3-pin configurations with consistent quality and dimensions. This standardization simplifies your sourcing process and reduces the complexity of managing spare parts.

Global Compliance and Safety: Our connectors are designed to meet international electrical safety and performance standards, giving you the confidence to deploy them in global markets.

Versatility Across Applications: The availability of both pin configurations and a wide range of compatible cable diameters makes this product series a versatile solution for powering everything from a single outdoor light to a complex piece of automation machinery.

Product Application Fields

The versatility and robustness of our 2-pin and 3-pin waterproof connectors make them suitable for a vast array of industries:

Outdoor LED Lighting: Essential for connecting LED street lights, landscape lighting, floodlights, and architectural lighting systems, where they are exposed to rain and temperature fluctuations.

Industrial Automation and Machinery: Used on factory floors for sensors, actuators, motors, and control panels that require a reliable connection despite exposure to coolants, dust, and constant vibration.

Automotive and Transportation: Ideal for wiring harnesses in commercial vehicles, buses, marine vehicles, and off-road equipment for lighting, signaling, and auxiliary power systems.

Security and Surveillance Systems: Provide dependable power and signal transmission for outdoor CCTV cameras, security sensors, and access control systems, ensuring uninterrupted operation.

Consumer Electronics and Outdoor Power Equipment: Used in electric vehicle charging accessories, garden tools, and portable power stations where a temporary or permanent waterproof connection is needed.

Display Screens and Signage: Critical for outdoor advertising displays and digital billboards, protecting the electrical connections from the elements.

New Energy and Marine Electronics: Applied in solar power systems, wind energy, and on-board electronic equipment on boats and yachts, resisting saltwater corrosion.

Product FQA

Q1: What is the difference between the IP67 and IP68 ratings mentioned?
IP67 certifies protection against temporary immersion in water (up to 1 meter for 30 minutes). Our connectors are rated IP68, which is a higher grade, guaranteeing continuous immersion in water under pressure (beyond 1 meter) as specified by the manufacturer, typically 1.5 meters for our products.

Q2: Can I mix and match a 2-pin plug with a 3-pin socket?
No, the 2-pin and 3-pin connectors are designed with different physical interfaces to prevent mismating. This is a critical safety feature that ensures correct electrical connections and prevents potential damage to equipment.

Q3: What is the maximum voltage and current these connectors can handle?
The specific ratings vary by wire gauge and connector model. Generally, our standard 2-pin and 3-pin connectors are rated for up to 250V and 16A. Please consult the detailed technical datasheet for specific model specifications.

Q4: What temperature range are these connectors rated for?
Our connectors are designed to operate reliably in a wide temperature range, typically from -40°C to +85°C (-40°F to +185°F), making them suitable for virtually all outdoor and most industrial environments.

Q5: Are these connectors compatible with different cable sizes?
Yes, we offer connector variants designed to accommodate a range of standard outer cable diameters (e.g., 3mm to 8mm). It is important to select the model that matches your cable's outer diameter to maintain the IP68 seal.

Q6: Do you offer custom cable assembly services?
Yes, as a full-service manufacturer, we can provide these connectors as standalone components or as pre-assembled waterproof cable harnesses, cut to your specified length and terminated to your requirements.
