Product Selling Points
1. Push-Lock Coupling for Quick and Secure Connections
Features push-lock coupling mechanism that enables one-handed, tool-free mating and unmating. Ideal for applications requiring frequent connection changes - such as industrial sensors, automation equipment, and portable devices - while providing reliable retention against vibration and pull forces.
2. IP67/IP68 Waterproof for Demanding Environments
Rated IP67 as standard, with IP68 available upon request. This M18 circular connector resists dust, temporary immersion, and continuous submersion in water. Perfect for outdoor lighting, marine equipment, industrial automation, and harsh-environment applications where moisture protection is essential.
3. Multiple Housing Material Options for Any Application
Choose from nickel-plated brass, stainless steel, or PBT housings to balance weight, corrosion resistance, and cost. Nickel-plated brass offers excellent durability, stainless steel provides superior corrosion protection for marine environments, and PBT delivers a lightweight, cost-effective solution for general industrial use.
4. Reliable Electrical Performance with UL94 V-0 Insulator
Gold-plated brass contacts ensure low contact resistance and excellent corrosion resistance. Supports 2 to 5 pins (custom options available) with a voltage rating of 250V AC/DC. PA66 insulator with UL94 V-0 flame rating adds safety, while the -40°C to 85°C temperature range and ≥100 mating cycles ensure long-term reliability.

Star Reviews From Customers
1.Michael Zhang, Automation Systems Integrator
"We deploy M18 push-lock connectors across our sensor networks. The quick-connect feature cuts panel wiring time by 40%, and the IP69K-rated versions endure daily wash downs in dairy processing without failure."
2. Lisa Chen, Robotics OEM Engineer
"Our collaborative robots use M18 push-lock connectors for tool interfaces. The secure click-lock prevents accidental disconnection during operation, and the compact size fits inside slender robot arms."
3. David Wilson, Packaging Line Technician
"On high-speed packaging lines, quick maintenance is critical. M18 push-locks let us swap sensors in seconds without tools-no more downtime from unscrewing threaded connectors."
4. Sophia Martinez, Agricultural Drone Manufacturer
"Dust and vibration are constant challenges in field robotics. These IP68-rated M18 connectors keep our drone payload connections secure and clean, season after season."
5. James Kim, Automotive Assembly Engineer
"We standardized on coded M18 push-locks for all our fixture sensors. The mechanical keying prevents mismating during line changeovers, reducing wiring errors to zero."
