When connectors are assembled incompletely or incorrectly, terminal back-outs can occur, causing end-product failure. Molex's Micro-Fit TPA, single-row receptacle resolves these issues by significantly reducing terminal back-out and virtually eliminating end-product failures caused by terminal back-outs. The reduction in terminal back-out is made possible by ensuring proper terminal seating and providing a secondary terminal retention feature. For example, assemblers cannot close the TPA unless the terminal is properly seated. Also, the receptacles provide backward compatibility with existing Micro-Fit 3.0 connectors and terminals, eliminating the need for customers to make major revisions or investments in their applications and enabling running change implementation to incorporate the TPA receptacle. Applications for Micro-Fit TPA, single-row receptacles include consumer and home appliances, data/computing (desktops, workstations, power supplies, and UPSs), telecommunications/networking (servers, routers, and switches), and automotive/commercial vehicle (harnesses, non-sealed applications, and inside devices). Single-row, wire-to-wire, and wire-to-board configurations are available immediately with two to seven circuits.
