Key Features

Diversified Material Options for Specific Environments

We offer three core material types: nylon waterproof connector (lightweight, cost-effective, corrosion-resistant), metal waterproof connector (high strength, anti-interference, suitable for heavy-duty use), and aviation waterproof connector (high precision, high temperature resistance, ideal for aerospace and industrial automation). Customers can choose based on environmental conditions and performance requirements.

Functional Classification for Signal & Power Stability

Our shielded waterproof connector effectively reduces electromagnetic interference (EMI) and radio frequency interference (RFI), ensuring stable signal transmission for sensitive equipment such as communication devices and sensors. The non-shielded waterproof connector is cost-efficient for general applications where interference is not a major concern.

Versatile Connection & Installation Methods

We provide multiple connection methods: quick-lock waterproof connector (fast and convenient, no tools required), threaded waterproof connector (secure and anti-loose, suitable for vibration-prone environments), and screw-lock waterproof connector (strong connection, high reliability). Installation options include assembled waterproof connector (easy to maintain) and injection-molded waterproof connector (integrated structure, better waterproof performance).

Precise Shape Customization for Space Adaptation

Our T-type waterproof connector and Y-type waterproof connector are designed for branch connections, saving installation space and simplifying wiring. We also support custom shapes for special equipment layouts, ensuring perfect fit in limited or irregular spaces.

High IP Rating & Harsh Environment Adaptability

All waterproof connector products have an IP65-IP68 protection grade, effectively blocking water, dust, oil, and chemicals. They can operate in extreme temperatures (-40℃ ~ 150℃), high humidity, and corrosive environments, ensuring long-term reliability in outdoor, marine, and industrial settings.

Marine & Offshore Equipment

The stainless steel waterproof connector (a type of metal waterproof connector) is corrosion-resistant to seawater and humid air. It is suitable for marine communication equipment, navigation instruments, and offshore oil drilling platforms, ensuring stable performance in harsh marine environments.

Communication & Networking Devices

The shielded waterproof connector and M12 waterproof connector are used in outdoor routers, base stations, and industrial Ethernet devices. They reduce signal interference and protect internal components from moisture, ensuring uninterrupted data transmission in outdoor or remote areas.

Customization Service Process

Requirement Communication & Material Selection

Customers consult our team to specify needs such as interface type (M6/M8/M12 or custom), protection grade, material (nylon/metal/aviation), connection method, shape, and application scenario. Our experts recommend suitable options based on practical requirements.

Interface & Function Specification Confirmation

We confirm key parameters with customers, including rated current, voltage, number of pins, shielding requirements, and installation space. For special needs (e.g., high temperature resistance, corrosion resistance), we conduct technical feasibility analysis and provide solutions.

Structural Design & Prototyping

Our R&D team designs the connector structure, including shell shape, sealing structure, and pin layout. We produce prototypes using 3D printing or mold processing, ensuring the design meets customization requirements.

Performance Testing & Optimization

Prototypes undergo strict testing, including waterproof testing (IP rating verification), temperature resistance testing, vibration testing, and signal transmission testing. We optimize the design based on test results to improve performance and reliability.

Batch Production & Quality Audit

After prototype approval, we start mass production using advanced injection molding, metal processing, and assembly equipment. Each customized waterproof connector undergoes 100% quality inspection, including visual inspection, electrical testing, and waterproof testing.

Delivery & Technical Consultation

We deliver products via reliable logistics and provide detailed installation guides. Our technical team offers post-delivery support, answering questions about installation, maintenance, and replacement.

Quality Assurance & After-Sales Support

Comprehensive Quality Inspection Protocol

We implement a strict quality management system, from raw material inspection (material composition testing, durability testing) to production process control (injection molding parameter monitoring, assembly precision inspection) and finished product testing (IP rating, electrical performance, mechanical strength).

Product Warranty & Defect Replacement

All waterproof connector products come with a 18-36 month warranty. If the product has quality defects (e.g., water leakage, poor contact) within the warranty period, we provide free replacement or repair.

24/7 After-Sales Consultation

Our after-sales team is available around the clock via email, phone, or online chat. We respond to customer inquiries within 2 hours and provide professional solutions for technical issues.

Customization Technical Support

For long-term cooperation customers, we assign dedicated technical account managers to track product usage, provide regular maintenance suggestions, and support future customization needs (e.g., parameter adjustments, shape modifications).

FAQ

What material options are available for your customized waterproof connector?

A: We offer three main materials: nylon waterproof connector (lightweight, cost-effective), metal waterproof connector (high strength, anti-interference), and aviation waterproof connector (high precision, high temperature resistance). Contact us for material recommendations based on your application scenario.

What IP rating do your waterproof connectors have?

A: Our standard products have IP65-IP68 ratings. IP65 is suitable for dust and low-pressure water spray; IP67 for short-term immersion (1m depth, 30 minutes); IP68 for long-term immersion (customizable depth). We can also develop higher protection grade products for special needs.

Can I customize the shape (T-type/Y-type) of the connector?

A: Yes. We support shape customization, including T-type waterproof connector, Y-type waterproof connector, and other special shapes. Provide your equipment’s installation space and wiring requirements, and our team will design a matching structure.

What is the lead time for customized waterproof connector?

A: For standard models (M6/M8/M12), delivery takes 3-5 working days. For customized models, prototype production takes 5-8 working days, and mass production takes 12-25 working days. Expedited services are available for urgent orders.

Do shielded waterproof connector really reduce signal interference?

A: Yes. Our shielded connectors adopt metal shielding layers or braided shielding structures, which can block 80-95% of electromagnetic interference (EMI) and radio frequency interference (RFI). They are highly recommended for communication devices, sensors, and other sensitive equipment.

Is injection-molded waterproof connector more durable than assembled ones?

A: Injection-molded connectors have an integrated structure with better waterproof performance and mechanical strength, suitable for harsh environments (e.g., long-term immersion, strong vibration). Assembled connectors are easier to maintain and replace, ideal for general applications. Choose based on your specific needs.
