TPA receptacles and cable assemblies eliminate assembly errors and prevent back-outs

Molex has introduced Micro-Fit TPA Single and Dual-Row Receptacles and Cable Assemblies designed to prevent failures due to terminal back-out and provide a secondary terminal retention feature. Terminal position assurance (TPA) technology ensures terminals are fully seated in the housing, and Micro-Fit TPA Single- and Dual-Row Receptacles also act as an ISL. These two features combined virtually eliminate terminal back-outs resulting from common assembly errors. The impact of terminal back-outs can range from customer frustration (faulty radio) to catastrophe (exposed live terminals) and result in liability costs to manufacturers and harm to individuals. Cost savings can be achieved by eliminating quality assurance checks to make sure terminals are inserted properly and avoid expensive service calls caused by terminal back-outs. “With Micro-Fit 3.0 compatibility, customers can incorporate the TPA product into their application with a simple running change to the housing part numbers,” said Pierre Perez, associate product manager, Molex. “Being able to implement a superior component without making significant revisions or investments will positively impact a company’s bottom line.”
