9mm High Voltage Interlock Loop Connector, 2 Pin Socket, A Key, 250A

Introduction

This 9mm High Voltage Interlock Loop (HVIL) Connector is a critical component designed for safe and reliable high-voltage connections in electric vehicles and industrial equipment. Engineered as a 2-pin socket with a straight orientation and an A Key configuration, it ensures proper mating and prevents incorrect connections within the high-voltage system. The connector features a robust PA66-GF housing, offering excellent mechanical strength and thermal stability. The heart of the connector is its 9mm diameter terminals, crafted from a high-conductivity copper alloy and finished with a silver plating to ensure minimal electrical loss and superior current carrying capacity. Its advanced interlock loop design is a key safety feature, enabling the system to detect disconnections and automatically de-energize the circuit before any access is possible.

Built to withstand demanding environments, this HVIL connector delivers outstanding performance and protection. It is rated for high-power applications, handling up to 1500V DC and 250A continuously. The connector achieves an IP67 rating, making it completely dust-tight and capable of withstanding temporary immersion in water, ensuring operational integrity in harsh conditions. Its materials comply with the UL94V-0 standard, providing high flame retardancy for enhanced safety. With a wide operating temperature range from -40°C to +125°C, this connector guarantees consistent performance in both extreme cold and high-heat scenarios, making it a dependable choice for the most rigorous automotive and industrial applications.

Key Features:

  • High-Current Capacity: Rated for 250A with silver-plated copper alloy terminals for optimal conductivity.
  • Enhanced Safety (HVIL): Integrated interlock loop ensures system de-energization upon disconnection.
  • Robust Environmental Protection: IP67 rated for complete protection against dust and water ingress.
  • High Voltage & Flame Retardant: Supports 1500V DC with a UL94V-0 flame-retardant housing.
  • Wide Operating Temperature Range: Reliable performance from -40°C to +125°C.
