Mini Manual Service Disconnect MSD Connector for Electric Vehicles, 2 Pin Socket, N Key, 400A, Shield
Introduction
This mini manual service disconnect (MSD) Connector is an essential high-voltage interlock component designed for electric vehicles. Engineered with an N key for secure mating, it ensures correct orientation and prevents mismating. The connector features a robust nylon housing, meeting the UL94V-0 flammability standard, and offers an IP67 rating for superior protection against dust and water ingress. Its panel mount design facilitates straightforward and secure installation in vehicle systems.
The connector is built for high-performance electrical demands, capable of handling up to 400A and a rated voltage of 700VDC. The silver-plated copper alloy contacts provide excellent conductivity and corrosion resistance, while the crimp termination ensures reliable, high-strength connections. The inclusion of a shielding shell is critical for protecting against Electromagnetic Interference (EMI), ensuring signal integrity in the sensitive electronic environment of an EV.
