Manual Service Disconnect MSD Connector, 2 Pin EV Plug, N Key, Shield, Panel Mount
Introduction
This high-performance MSD connector is engineered for electric vehicle power distribution systems requiring maximum safety, stability, and fault-tolerant operation. Featuring an N-keyed, 2-pin plug configuration, it ensures secure mating and mismatch prevention in high-voltage EV architectures. The panel-mount design provides robust integration into battery packs, power control units, and energy storage housings, while the shielded structure delivers superior electromagnetic protection in demanding environments.
Constructed with a durable nylon housing and silver-plated copper-alloy contacts, the connector delivers outstanding conductivity, heat resistance, and long-term reliability. Designed for crimp termination, it supports high-current performance across multiple ratings—200A to 630A—at an operating voltage of 800V. With IP67 protection, UL94 V-0 flame retardancy, and a wide operating temperature range from −40°C to 125°C, it delivers dependable performance in rigorous automotive and industrial conditions.
