Molex Mini-Fit Sr. Power Connectors

Molex Mini-Fit Sr. Power Connectors are compact with excellent electrical reliability, supporting up to a 50.0A current rating. These compact connectors feature a polarized housing that prevents connector mismating; the Mini-Fit Sr. Power Connectors offer silver-plated contacts that are significant in cost savings over gold-plated systems. To ensure superb contact reliability these connectors have a dual-beam (female) terminal design providing four contact points and a Terminal Position Assurance (TPA) retainer to prevent terminal back-out. Molex Mini-Fit Sr. Power Connectors feature a maximum voltage rating of 600V AC/DC, offers contact resistance up to 1.0 milliohm and insulation resistance as high as 1000 megohm.

Features

Dual-beam (female) terminal design
- Gives four points of contact and ensures superb contact reliability
