Product Details
Mini-Fit Junior 4.2mm Crimp Receptacle and Plug Housings
Mini-Fit Junior 4.2 mm pitch crimp receptacle and plug housings which form part of the Mini-Fit Junior power connectors interconnection system. Mini-Fit Junior power connectors are able to handle up to 13A per circuit making them ideal for use in high current applications. These Mini-Fit Junior crimp housings have fully isolated terminals for protection against, debris, arcing and damage caused by mishandling. The housings incorporate polarization and keying features to prevent misalignment and mismating. A positive locking mechanism consisting of an easy to operate thumb latch provides a secure connection with the mating connector. This positive locking mechanism prevents accidental unmating caused by excessive shock or vibration. An audible click indicates that the connector is fully mated. These Mini-Fit Junior 4.2 mm plug and receptacle housings are available with a UL94V-0 or UL94V-2 housing material, a range of contact configurations and accept standard Mini-Fit and Mini-Fit Plus crimp terminals
