Core Parameters: Adopts M19 circular size with 3+4 Pin separate design, 3 Pins for low-voltage power transmission and 4 Pins for signal transmission. It meets the 300V low-voltage standard, adapts to various low-voltage equipment, realizes independent transmission of power and signal without mutual interference, and balances practicality and safety.
Low-Voltage Safety Features: Strictly follows the 300V low-voltage design standard, with excellent insulation performance, effectively preventing safety hazards such as short circuits and leakage of low-voltage circuits. It is suitable for various low-voltage equipment with strict voltage requirements, ensuring the safe operation of equipment and the personal safety of operators.
Core Advantages of Gold Plating: The contacts are made of high-quality brass substrate, with precision gold plating on the surface. The gold plating layer is uniform and dense, which not only reduces contact impedance, reduces power loss and signal interference, but also enhances oxidation resistance and corrosion resistance, adapting to harsh environments such as humidity and heavy dust, and extending the service life of the connector.
Waterproof Performance: Adopts a fully sealed waterproof structure with high-elasticity waterproof sealing ring, reaching IP67 protection level. It can effectively block the intrusion of water vapor, dust, oil stains and other impurities, adapting to harsh scenarios such as outdoors and wet workshops, ensuring stable and uninterrupted low-voltage power and signal transmission.
Structure and Installation: M19 circular structure design, compact size, suitable for various installation scenarios, supporting flexible wire-to-wire and wire-to-board connection. It is easy to install and precise in positioning, with firm wiring that is not easy to fall off, which can quickly complete assembly and improve production and maintenance efficiency.
Application Scope: Widely used in low-voltage industrial control equipment, small outdoor lighting, household smart equipment, medical auxiliary equipment, security inspection equipment, small new energy equipment and other fields, especially suitable for 300V low-voltage scenarios that need to simultaneously achieve power supply and signal transmission and have waterproof requirements.
