Ultra-miniature circular waterproof connector, 4 cores

Product Overview： Our ultra-miniature circular waterproof 4-core connector is a high-precision compact connection solution designed exclusively for space-constrained miniature electronic devices requiring integrated multi-signal and power transmission. Optimized from 2-core and 3-core miniature connectors, this 4-core circular model is equipped with four fully isolated independent circuits, effectively solving the problem of insufficient transmission channels for basic low-core connectors. It supports synchronous stable power supply and multi-group signal data transmission, eliminating the need for multiple connector combinations and messy internal wiring in precision equipment. Adopting integrated one-piece overmolding sealing technology and industrial-grade anti-aging materials, this ultra-miniature circular connector boasts excellent IP67 waterproof, dustproof, anti-vibration and anti-electromagnetic interference performance. It maintains long-term stable operation in outdoor humid, dusty, low-temperature and vibration-intensive harsh environments, serving as a reliable high-integration wiring accessory for smart home precision devices, automotive micro-electronic systems, industrial mini sensors and portable intelligent equipment. Featuring an ultra-tiny streamlined circular body and professional 4-core isolated circuit design, this waterproof connector effectively prevents signal crosstalk, current fluctuation and power transmission loss. Its ultra-miniature compact structure minimizes installation space occupation, greatly simplifies complex internal wiring layouts, and significantly improves equipment assembly neatness and operational stability, fully adapting to the miniaturization, lightweight and high-density integration development trend of modern sophisticated electronic equipment.

Core Features & Advantages

Ultra-Miniature Circular Compact Structure: Adopts optimized micro circular miniaturized design with ultra-small overall volume, effectively saving valuable equipment installation space. It perfectly adapts to narrow embedded installation and dense hidden wiring scenarios that ordinary standard connectors cannot meet, enabling flexible assembly and standardized neat wiring for high-precision mini equipment.

4-Core Independent Multi-Channel Transmission: Four fully isolated independent core channels support simultaneous multi-path power supply and multi-group signal transmission. It upgrades the channel limitation of 2/3-core connectors, meeting complex multi-signal feedback and multi-point control demands of precision devices without additional wiring expansion or auxiliary accessories.

Industrial-Grade IP67 Waterproof & Dustproof: Built with integral overmolding sealing craft and high-elasticity waterproof rubber ring, forming a fully enclosed protective barrier. It effectively resists rain immersion, water splashing, dust accumulation, moisture erosion and oxidation aging, ensuring consistent and reliable electrical performance in complex outdoor and industrial harsh working environments.

High-Durability Industrial-Grade Materials: The circular shell is made of flame-retardant, compression-resistant and anti-bending high-strength engineering plastic, with excellent low-temperature resistance and long-term anti-aging performance. Internal conductive cores adopt high-purity oxygen-free copper with anti-oxidation nickel plating, featuring ultra-low resistance, high conductivity and outstanding corrosion resistance.

Precision Anti-Loose Anti-Vibration Locking Design: Professional circular docking and tight locking structure ensures seamless and firm fitting after assembly. It effectively avoids poor contact, signal interruption and circuit failure caused by long-term mechanical vibration, equipment shaking and external pulling, guaranteeing continuous and safe circuit operation.

Plug-and-Play & Universal Compatibility: Tool-free quick plug-and-play installation greatly simplifies assembly and maintenance procedures, improving production efficiency and after-sales convenience. Compatible with universal AWG24-AWG28 fine wires, it is widely applicable to various ultra-small low-power and high-precision multi-signal electronic devices.
