Molex Debuts Micro-Fit™ TPA Single Row Receptacle

June 16, 2016
By Business Wire News


Molex has introduced the Micro-Fit™ TPA Single Row Receptacle, which offers a TPA integrally molded with the housing. The integrated TPA (terminal position assurance) feature ensures terminal seating.

“When connectors are assembled incompletely or incorrectly, terminal back-outs can occur, causing end-product failure,” said John Luthy, product manager, Molex. “This can produce problems ranging from intermittent operation to complete product failure. The 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 new 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 2 to 7 circuits. For 8 to 12 circuit configurations, contact Molex.
