8mm HVIL High Voltage Interlock Loop Connector, 3 Pin Plug, A Key, 50mm², 250A
Introduction
Ensure the safety and integrity of your high-voltage systems with our 8mm HVIL High Voltage Interlock Loop Connector. This 3 Pin Plug is engineered to provide a critical safety loop, continuously monitoring the connection status within electric vehicle powertrains, battery packs, and charging systems. Its straight-direction design facilitates easy installation and efficient cable management in compact spaces. The connector features a keyed A Key interface, guaranteeing foolproof mating and preventing mismating with incompatible components. Constructed with a high-strength PA66-GF housing, it offers excellent resistance to impact, chemicals, and elevated temperatures.
This connector is built to deliver uncompromising performance under the most demanding conditions. It is rated for 1500V DC and a continuous current of 250A, supported by a robust 50mm² wire gauge with shielding for effective EMI protection. The silver-plated copper alloy contacts ensure maximum conductivity, minimal voltage drop, and long-term corrosion resistance. With an IP67 rating, it is completely protected against dust ingress and temporary immersion in water, while its UL94V-0 certified housing provides critical flame retardancy. Operating reliably across a wide temperature range from -40°C to +125°C, this connector is a durable and safe solution for automotive and industrial applications.
