40A HVIL High Voltage Interlock Loop 3 Pin Connector, Plug, A Key, 800V
Introduction
The 40A HVIL High Voltage Interlock Loop 3 Pin Connector is a critical component for safe and reliable power and signal integration in electric vehicle and energy systems. This Straight Plug features an A Key to prevent misalignment and utilizes a 3 Pin configuration, accommodating both high-voltage power and essential control signals. It is designed for 6mm² shielded wire, ensuring efficient 40A current transfer at 800V DC while maintaining electromagnetic integrity. The core HVIL function guarantees that the low-voltage safety circuit is broken before the power contacts disengage, providing crucial personnel protection.
Constructed for high reliability, the housing is made of durable PA66-GF, complemented by Tin-Plated Copper Alloy contacts for robust electrical conductivity. Environmental protection is certified IP67, offering resistance to dust and moisture, while the UL94V-0 rating ensures flame retardancy. It operates flawlessly across a wide range of thermal conditions, from -40°C to 125°C.
