Mini-Fit TPA2 Power Connectors

Molex Mini-Fit TPA2 Power Connectors offer terminal position assurance (TPA) with a secondary locking feature. This reduces assembly error and ensures the terminals are fully seated and will not back out. A positive-lock receptacle offers an audible click while mating, preventing the mated connector assemblies from accidentally disengaging. Fully isolated header pins and plug and receptacle terminals protect contacts against potential damage during handling and mating. Molex Mini-Fit TPA2 Power Connectors are compatible with existing Mini-Fit Jr. headers and plugs to incorporate TPA2.0 designs, removing the need to change both sides of the interface or to make significant revisions or investments in applications. Ideal applications include data/communications, automotive, industrial automation, and home appliances.
