Mini Manual Service Disconnect MSD Connector, 2 Pin EV Plug, N Key, Shield
Introduction
The Mini Manual Service Disconnect (MSD) is a critical safety component designed for high-voltage Electric Vehicle (EV) battery packs and Power Distribution Units (PDU). This 2-Pin Plug features precise N Keying to ensure correct mating and prevent mismatching during maintenance. Engineered for Panel Mount installation with secure Crimp termination, this connector provides a tool-free solution for disconnecting the high-voltage internal circuit, ensuring the safety of technicians during service and inspection. It also features integrated shielding to minimise electromagnetic interference (EMI), a crucial requirement for modern automotive electronics.
Built to withstand rigorous operating conditions, the connector housing is crafted from durable Nylon with a UL94V-0 flame-retardant rating, while the contacts are made of Silver-Plated Copper Alloy to ensure excellent conductivity and minimal heat rise. The system is highly versatile, supporting a wide range of rated currents—200A, 250A, 315A, 350A, and 400A—at voltages of 690VDC / 700VDC. With an IP67 protection rating and an operating temperature range of -40°C to 125°C, this MSD connector guarantees reliable power isolation even in the harshest environmental conditions.
