Product Selling Points

 

1. Screw-Lock Coupling for Secure Connections
Features threaded screw-lock coupling that provides reliable mechanical retention in high-vibration environments. Ideal for industrial controls, automation equipment, and heavy machinery - preventing accidental disconnection and ensuring uninterrupted operation.

2. Optional IP67/IP68 Waterproof Protection
Rated IP67 as standard, with IP68 available upon request. This M16 circular connector resists dust, temporary immersion, or continuous submersion in water. Perfect for outdoor lighting, marine electronics, sensors, and harsh-environment applications where moisture protection is essential.

3. Wide Voltage Range with Flexible Pin Configurations
Supports 2 to 8 contact pins with a voltage rating from 60V to 300V - accommodating both low-voltage signal transmission and higher-power applications. Suitable for factory automation, renewable energy systems, and industrial fieldbus connections.

4. High-Temperature Materials with UL94-V0 Flame Rating
Operating temperature range from -40°C to 125°C ensures reliable performance in extreme environments. Choose from silver-plated brass or gold-plated copper alloy contacts, with PA66, PBT, or high-temperature thermoplastic insulators. UL94-V0 flame rating provides additional safety for demanding applications.

Star Reviews From Customers

 

1.Lisa Chen, Solar Farm Engineer
"Outdoor junction boxes for solar trackers use M16 connectors for motor and sensor links. The UV-resistant housing and corrosion-resistant plating withstand decades of sun, rain, and temperature swings."


2.David Wilson, Marine Equipment Supplier
"Saltwater exposure kills standard connectors. We deploy nickel-plated brass M16 connectors on navigation buoys and dock equipment-no corrosion issues even after years in seawater spray."


3.Sophia Martinez, Electric Vehicle Charging Designer
"For outdoor EV charging cables, we need robust, user-friendly connectors. The M16 screw-lock provides secure mating and IP67 sealing, ensuring safety in all weather conditions."
