Manual Service Disconnect MSD Connector for EV, 2 Pin Socket, N Key, 630A, Shield
Introduction
This high-performance MSD connector is designed for electric vehicle power distribution systems that require maximum safety, high current capacity, and stable signal integrity. Designed with an N-key orientation and a 2-pin configuration, it ensures secure mating and reliable polarity control in demanding EV architectures. The connector features a robust shielded structure to minimise electromagnetic interference and maintain system stability in high-power environments.
Built with a durable nylon housing, copper-alloy contacts, and a silver-plated surface finish, this MSD connector delivers excellent conductivity, low contact resistance, and long-term reliability. Its crimp-termination design and panel-mount structure enable fast, stable installation in battery packs, power control units, and energy modules. With a rated current of 630A and voltage up to 800V, it provides the high-power handling required for next-generation electric vehicles.
Engineered for harsh operating conditions, the connector supports an extended temperature range from –40°C to +125°C and meets IP67 waterproof protection. Its UL94V-0 flame-retardant rating ensures enhanced safety and fire resistance in mission-critical EV systems, making it ideal for high-voltage disconnect applications.
