8mm High Voltage Interlock Loop HVIL 1 Pin Connector, Socket, A Key, 250A
Introduction
The 8mm HVIL Connector is engineered for high-voltage power distribution and safety interlock systems in electric and hybrid vehicles. Featuring a straight configuration and A-key design, this socket connector ensures precise mating and secure interlocking with its corresponding plug. Its 1-pin structure with an 8mm terminal diameter supports efficient high-current transmission while maintaining low contact resistance.
Constructed with a PA66-GF housing, the connector provides superior mechanical strength, thermal stability, and flame retardancy (UL94V-0). The copper alloy contacts are silver-plated to enhance electrical conductivity and corrosion resistance under demanding conditions. Designed for rated voltage up to 1500V DC and current up to 250A, it guarantees reliable power delivery in high-voltage environments. The shielded structure offers excellent electromagnetic interference (EMI) protection, ensuring system stability and safety.
This HVIL connector meets IP67 waterproof protection, providing complete sealing against dust and moisture, while operating efficiently in extreme temperatures from -40°C to +125°C. It is an ideal choice for EV battery packs, power control units, and energy storage systems requiring safe and stable high-voltage connections.
