IP67-rated plastic circular connectors deliver up to 15A current capacity, 3,000 mating cycles, and V-0 flame retardancy
Shenzhen Xmost Industry Co., Ltd. has unveiled a new plastic circular connector series in M8, M12, and M16 sizes, offering both quick bayonet and threaded screw coupling options across male and female variants. Engineered for demanding industrial and outdoor environments, the new series combines IP67-rated waterproof protection, up to 3,000 mating cycles, and V-0 flame retardancy – delivering a lightweight, durable, and cost-effective interconnection solution for factory automation, outdoor lighting, solar energy systems, and EV charging infrastructure.
Product Advantages
new connector series features a PA66 nylon housing with V-0 flame retardant rating, providing excellent electrical insulation, corrosion resistance, and significant weight savings over metal-shell alternatives.
Flexible Pin Configurations and High Current Capacity
Available in 2-pin to 12-pin configurations, the series scales to meet diverse power and signal transmission requirements. The 2-pin and 3-pin variants support up to 15A at 500V AC, ideal for power delivery applications. The 4-pin configuration handles 8A, while 8-pin and 12-pin versions deliver 3A per contact for signal and low-power applications. Contact resistance is maintained below 5mΩ with insulation resistance exceeding 100MΩ.
Extended Service Life – 3,000 Mating Cycles
connectors feature gold-plated brass or phosphor bronze contacts, ensuring stable signal transmission and corrosion resistance. The 2-pin, 3-pin, and 4-pin variants are rated for 3,000 mating cycles – well above the industry-standard 500 cycles – providing reliable performance in applications requiring frequent connection and disconnection.
Dual Coupling Mechanisms for Application Flexibility
- Quick bayonet coupling – enables fast, tool-free mating with an audible click, ideal for field installations and maintenance
- Threaded screw coupling – delivers secure, vibration-resistant locking with controlled torque, suitable for machinery and vehicle applications
Wide Temperature Range and Environmental Sealing
Rated for -40°C to +105°C (2-pin to 4-pin variants), the connectors perform reliably in extreme cold and high-heat environments. IP67-rated sealing ensures complete dust protection and temporary water immersion resistance, making them suitable for outdoor and washdown applications. Multiple wiring methods – including solder and screw crimping – accommodate wire gauges up to 1.5mm² (16 AWG).
Applications
Industrial Automation and Control
M8 and M12 connectors provide reliable sensor and actuator connections in factory automation, PLCs, and distributed control systems. Threaded coupling ensures vibration resistance, while bayonet options enable rapid field servicing.
Outdoor LED Lighting and Signage
IP67 sealing and UV-resistant PA66 housing make the series ideal for streetlights, architectural lighting, and digital signage. Lightweight plastic construction reduces fixture weight, and bayonet coupling simplifies installation and maintenance at height.
Renewable Energy Systems
Solar junction boxes, combiner boxes, and inverter connections benefit from the wide temperature range and corrosion resistance. The 2-pin and 3-pin 15A variants support power transmission in photovoltaic systems.
EV Charging Infrastructure
The series supports auxiliary connections in EV charging stations, with 500V AC rated voltage and high-current variants accommodating power delivery requirements.
