High Voltage Interlock Loop 4 Pin EV Connector, Socket, A Key, 6mm², 40A

Introduction

This 4-pin straight socket connector is engineered for robust performance in electric vehicle high-voltage interlock loops (HVIL). Constructed with a PA66-GF material shell offering UL94V-0 flame resistance, it ensures superior protection in demanding environments. The copper alloy contacts, finished with a reliable tin plating, are designed for a 6mm² shielded wire, guaranteeing stable power transmission and signal integrity. Rated for 800V DC and 40A, this connector is built to handle the high-power demands of modern EV systems. Its IP67 rating provides complete protection against dust and temporary immersion, while the operating temperature range of -40°C to +125°C ensures consistent performance in extreme conditions. The integrated A-key polarization prevents mismating, enhancing safety and reliability.
