Micro-Fit TPA 3.0 mm Crimp Receptacle Housings

Micro-Fit TPA 3.0 mm single and double row crimp receptacle housings that feature a TPA (terminal position assurance) with an integrated secondary lock. The single row Micro-Fit housings have a one piece design that incorporates the TPA, the double row versions are supplied with a separate 2 piece TPA. The TPA and integrated secondary lock prevent terminal backouts resulting from improper assembly. The one piece design of the single row Micro-Fit TPA housing removes the need for secondary pieces which can easily be lost. The housings of these Micro-Fit TPA 3.0 mm receptacle housings are polarized to prevent accidental mismating and feature locking latches for a secure mating connection. The contacts are fully isolated within the housing to prevent arcing. These Micro-Fit TPA 3.0 mm receptacle connectors are compatible with existing Micro-Fit 3.0 headers and plugs enabling a TPA design to be implemented into existing systems without incurring further costs
