Mini-Fit Sr. Power Connectors

Molex Mini-Fit Sr. Power Connectors support up to 50.0A current with superb electrical reliability and significant cost-savings over a vast range of industrial, consumer, automotive, medical, and telecommunication/networking applications. The compact connectors feature a polarized housing that prevents connector mismating and silver-plated contacts. A dual-beam (female) terminal design provides four contact points to ensure superb contact reliability, and a Terminal Position Assurance (PTA) retainer prevents terminal back-out.
