Quick Details of IP67 Waterproof connector

4-Pin High-current Pure Power Design: Adopting a standardized 4-pin full-power channel layout, this connector is customized for 50A super high-current transmission without signal interference. The balanced pin arrangement ensures even current distribution, stable high-power output and no current deviation, perfectly serving as the main power docking solution for various heavy-duty electrical equipment.
50A Super High Current Carrying Capacity: Rated at 50A large current, it is equipped with thickened and widened high-purity copper terminals with large conductive area and low resistance. It maintains low heat generation and stable performance under long-term full-load operation without virtual connection or power attenuation, ensuring reliable power supply for heavy-duty industrial and energy storage equipment.
High-strength Flame-retardant PA66 Housing: Integrally injection-molded with modified PA66 nylon material, the housing features high rigidity, high toughness and strong impact resistance. With excellent flame retardancy, insulation and high voltage resistance, it effectively prevents electric leakage and short circuits, and delivers outstanding tensile, bending and aging resistance for long-term industrial application.
Complete Male & Female Matching Design: Supplied with matched male and female connectors for flexible wire-to-wire connection. It supports power cable extension, transfer and capacity expansion, adapting to equipment external power connection, equipment assembly wiring and heavy-duty circuit renovation with high flexibility and universality.
Tool-free Thread-free Quick Lock Structure: Featured with professional quick-lock self-locking design, the male and female terminals can be automatically locked by simple pushing. The tight anti-loosening structure resists equipment vibration and external pulling. Press-to-release enables fast manual assembly and disassembly, improving wiring and maintenance efficiency and supporting frequent repeated plugging.
Standard M25 Specification with Excellent Heat Dissipation: Adopting industry-standard M25 circular size with sufficient insulation spacing to avoid creepage and breakdown risks under heavy load. The large internal cavity accelerates heat dissipation, reduces operating temperature rise effectively, and greatly improves overall operation safety and service life under high-current working conditions.

Nagtry na kami ng maraming brand ng waterproof connector, ngunit ito ang pinakamatibay. Hindi tumatagas ng tubig kahit sa malakas na ulan, hindi nagkakaroon ng short circuit, safe gamitin. Ang pre-sales at after-sales na serbisyo ay napakabait, mabilis tumugon at tumutulong sa amin sa lahat ng problema.
