High-current wire-to-wire and wire-to-board connectors operate to 50A

Mouser is now stocking Molex Mini-Fit Sr. connectors. For use in wire-to-wire and wire-to-board applications, the Mini-Fit Sr. connectors are a powerful extension to the proven Mini-Fit family. The high-current cabling interconnect system is capable of handling up to 50A using 8 AWG wire, and offers outstanding electrical reliability and a significant cost savings over a broad range of applications. The Molex Mini-Fit Sr. connectors are based on a dual-beam female terminal design consisting of four points of contact to ensure superb electrical contact performance and reliability. They feature silver-plated contacts and a polarized housing; the contacts offer significant cost-savings over gold-plated systems to help avoid the need to manually lubricate tin-plated versions to reduce fretting corrosion, while the polarized housing prevents connector mis-mating of the header and receptacle or plug and receptacle. To prevent accidental un-mating, the connectors also offer a positive locking feature that ensures secure retention when the receptacle and header or receptacle and plug are mated. Other features include a Terminal Position Assurance (TPA) retainer to ensure that the terminals are fully seated in the housings to help reduce the risk of terminal back out, and fully isolated header pins and plug receptacle terminals to protect against potential damage during handling and mating. The highly-robust high-current interconnects are suitable for a variety of industrial, consumer, telecommunications, medical, power supply, and automotive applications.
