M19 High Current Wire To Board Connector 300V Male Female Connector 4 Pin
IP67 Waterproof M19 4 Pin Male To Female Outdoor Connector
The M19 series 4Pin Wire-to-Board (WTB) male and female connector is engineered for high-current transmission applications, featuring a 15A current rating and 300V voltage rating. Its robust construction and stable electrical performance make it an ideal solution for industrial and equipment connections. The male-female pairing design ensures reliable connections between wires and circuit boards, while the 4-pin configuration meets signal and power transmission requirements for medium to high-power equipment.
Constructed with glass fiber-reinforced nylon housing compliant with UL94 V0 flame-retardant standards, this connector offers exceptional high-temperature resistance, corrosion resistance, and insulation properties. It operates reliably in temperature environments ranging from -40℃ to 105℃. The high-conductivity brass contacts with gold plating feature contact resistance below 10mΩ, insulation resistance exceeding 500mΩ, and withstand voltage up to 1000V, ensuring minimal loss and heat generation during high-current transmission.
Featuring optional push-pull self-locking or plastic thread fixing mechanisms, the connector maintains secure connections even in industrial vibration environments. Compliant with RoHS environmental standards and certified by CE and UL, it finds applications across industrial automation equipment, power modules, LED displays, medical devices, and new energy systems.
