Molex Mini-Fit Sr. Connector, Custom Wire Harness Manufacturer

Molex Mini-Fit Sr. Connector

The Molex Mini-Fit Sr. Power Connectors deliver outstanding performance with a current rating of up to 50.0A, making them ideal for a broad spectrum of demanding applications, including industrial equipment, consumer electronics, automotive systems, medical devices, and telecommunications and networking infrastructure. These connectors are designed for high electrical reliability, featuring a compact, polarized housing that prevents mismating, ensuring safe and accurate connections. Equipped with silver-plated contacts, they resist corrosion and maintain efficient conductivity over time. The female terminals incorporate a dual-beam design with four contact points, enhancing contact reliability and reducing the risk of electrical interruptions. Additionally, the connectors are secured by a Terminal Position Assurance (PTA) retainer, which prevents terminal back-out, thus further safeguarding connection integrity under rigorous usage conditions. This cost-effective, high-performance solution meets the needs of various industries where consistent power delivery and robust design are essential.
