Over the past decade, the M16 connector industry in China has evolved from "assembly and imitation" to "independent innovation". Currently, domestic M16 connectors have reached the same level as international brands in terms of waterproof performance (IP67/IP68), high-density integration (24 cores), anti-vibration design, and EMC shielding. They also possess the advantages of rapid delivery, flexible customization, and cost optimization. According to the "2025 China Industrial Connectors White Paper", the market share of domestic M16 in the fields of new energy, robots, and rail transportation has exceeded 65%.

6. Luxshare

Relying on its advantages in consumer electronics manufacturing, it has entered the industrial connector market in recent years. The M16 automated production line is highly efficient and is suitable for large-scale production of standard products.

7. ERMA

Focus on waterproof connectors, the M16 series features IP68+ salt spray test for 1000 hours, commonly used in outdoor LED and charging stations.

8. KJT

The cost-performance route represents that the products cover the entire series of M8/M12/M16, and are suitable for entry-level purchases by small and medium-sized equipment manufacturers.

9.Lemo China

Although it is a Swiss brand with a Chinese factory, its localized production makes it a "domestic alternative" option for the high-end market. The M16 aviation plug style products are stable.

10. Griffin Conn

An emerging brand, focusing on the new energy sector, the M16 high-voltage connector supports 600V/10A and is suitable for energy storage and charging stations.
