Our M Series circular connectors are engineered with rigorously selected materials to ensure durability and reliability. The metal version features a nickel-plated brass housing for corrosion resistance, impact protection, and EMI shielding. The plastic model uses high-strength PA66 engineering plastic, offering excellent weather and chemical resistance for long-term waterproof integrity. All terminals are gold-plated brass, providing efficient conductivity and oxidation resistance for stable signal transmission. Full material compliance with environmental standards is assured.

In contrast, some manufacturers use unplated brass (prone to rust), low-cost ABS or recycled plastics (liable to degrade), and untreated brass terminals (susceptible to oxidation and poor contact). Our material strategy prioritizes structural integrity and performance consistency, delivering superior waterproofing, longevity, and overall value in demanding applications.
