8mm High Voltage Interlock Loop 3 Pin Connector, Socket, A Key, 250A

Introduction

This 8mm High Voltage Interlock Loop (HVIL) 3-Pin Connector in a Socket configuration is engineered for superior performance and safety in high-voltage electric vehicle and energy storage applications. Designed as a straight connector with an A Key polarization system, it ensures a foolproof, mis-mating-proof connection, safeguarding your electrical systems. The connector boasts a robust construction, featuring a PA66-GF shell for excellent mechanical strength and heat resistance, and copper alloy contacts with a silver plating to ensure minimal electrical loss and high conductivity. Its 8mm shielded terminals and full connector shielding are critical for protecting signal integrity against electromagnetic interference (EMI).

Built to withstand demanding environments, this HVIL connector delivers exceptional reliability with an IP67 rating, making it completely dust-tight and capable of withstanding immersion in water. It operates flawlessly across a wide temperature range from -40°C to +125°C. The combination of a 1500V DC rated voltage and a high 250A current capacity makes it ideal for primary power distribution circuits. Furthermore, the housing material complies with the UL94V-0 standard, providing superior flame retardancy for enhanced system safety and compliance with industry regulations.

Key Features:

  • High Current & Voltage: Rated for 250A and 1500V DC, perfect for main power lines.
  • HVIL Safety Loop: Integrated interlock system ensures safe power-on/power-off sequencing.
  • Robust Environmental Sealing: IP67 protection against dust and water ingress.
  • Secure & Keyed Connection: A Key design prevents incorrect mating for operational safety.
  • Durable Construction: PA66-GF housing (UL94V-0) and silver-plated contacts for reliability.
