Micro-miniature circular 3-pin waterproof connector

Product Overview： Our micro-miniature circular 3-pin waterproof connector is a ultra-compact round connection solution engineered for space-limited precision devices that require simultaneous signal and power transmission. Different from single-function 2-core connectors, this 3-pin circular design supports matched power and signal synchronous transmission, solving the common wiring problems of insufficient pins and messy separate wiring in miniature equipment. Adopting precision circular docking structure and industrial-grade sealing technology, this tiny waterproof plug delivers stable connection, excellent dustproof and waterproof performance, and strong environmental tolerance. It works reliably in outdoor, humid, dusty and vibration-intensive scenarios, serving as an ideal mini wiring accessory for modern smart, industrial and portable electronic devices. Featuring a micro-miniature round outline and standardized 3 independent pin channels, this connector avoids signal crosstalk and current loss while realizing multi-circuit integrated connection. Its ultra-light and embedded-friendly structure perfectly fits the miniaturization trend of precision equipment, greatly simplifying internal wiring and improving overall assembly neatness and stability.

Application field： Smart Home Devices，Outdoor Monitoring & Lighting，Automotive Micro Electronics，Industrial Precision Equipment，Wearable & Consumer Electronics

Core Features & Advantages

Micro-Miniature Circular Form Factor: Optimized ultra-small round structure minimizes installation space occupation, perfectly suited for dense wiring and narrow embedded installation scenarios. The streamlined circular profile ensures easy assembly and tidy layout without occupying extra equipment internal space.

3-Pin Independent Signal & Power Transmission: Three independent pin channels support integrated power supply and signal transmission, meeting the working demands of equipment that requires power input and signal feedback at the same time. Isolated circuit design effectively eliminates crosstalk, ensuring low-loss, high-stability circuit transmission.

Industrial-Grade IP67 Waterproof & Dustproof: Adopts integral overmolding process and high-elasticity waterproof rubber ring to form a fully enclosed sealing structure. It effectively resists rain immersion, water splashing, dust accumulation and moisture corrosion, maintaining stable performance in harsh outdoor and wet industrial environments.

High-Strength Anti-Aging Materials: The connector shell is made of flame-retardant and anti-aging engineering plastic, with high-purity oxygen-free copper pins with anti-oxidation plating. It features excellent vibration resistance, bending resistance and corrosion resistance, supporting long-term continuous operation and frequent plugging and unplugging.

Precision Locking & Stable Docking: Built-in professional circular locking structure enables tight plug-and-socket fitting after docking. It effectively prevents loose connection and intermittent circuit failure caused by external vibration, shaking and pulling, ensuring continuous and safe circuit connection.

Plug-and-Play & Strong Compatibility: Tool-free quick plug-and-play design greatly improves production and maintenance efficiency. Compatible with fine gauge wires, it is widely adaptable to various miniature smart devices and precision low-power equipment wiring.
