According to industry research, the global industrial connector market is expected to exceed USD 85 billion in 2026, with waterproof connectors accounting for ~18% of the total. Growth is driven primarily by new energy storage, PV, industrial automation, outdoor equipment and rail transit. Aligning with downstream equipment trends toward “compact, tool-free, high reliability”, self-locking, threadless, IP67-rated waterproof connectors are becoming the mainstream choice.

Key Trend 1: New energy storage boosts demand for M25 high-current self-locking connectors
Energy storage battery clusters, PCS inverters and commercial/industrial storage cabinets require M25 size, multi-pin (3+3/3+9), split-current (15A+5A), self-locking threadless waterproof connectors. IP67 protection, vibration resistance and long-term stability are essential, replacing traditional threaded connections for faster installation and higher reliability.

Key Trend 2: Industrial automation favors M16/M19 compact self-locking connectors
In robotics, servo motors, sensors and industrial cameras, M16/M19 self-locking connectors (3–12Pin, IP67, tool-free) are replacing traditional circular connectors due to easy installation, vibration resistance and suitability for confined spaces, becoming the standard choice for OEMs.

Key Trend 3: IP67 baseline for outdoor equipment; threadless design preferred
For outdoor LEDs, security devices, agricultural machinery and charging piles, IP67 has become the minimum protection requirement. Meanwhile, threadless self-locking structures avoid thread rust, wear and misoperation, making them ideal for outdoor and vibrating environments, with increasing market penetration.

Ulinkcon focuses on M16/M19/M25 self-locking waterproof connectors, continuously optimizing threadless structures and IP67 protection designs to align with market trends and customer needs, helping global OEMs improve product reliability and installation efficiency.
