Mini-Fit Junior 4.2 mm pitch PCB headers which form part of the Mini-Fit Junior power connector interconnection system. Mini-Fit Junior power connectors are able to handle up to 9A per circuit making them ideal for use in high current applications. These Mini-Fit Junior PCB headers have fully isolated terminals for protection against, debris, arcing and damage caused by mishandling. The connector housings are also scoop-proof which prevents damage to the pin terminals when mated at a severe angle. The housings of these PCB headers incorporate polarization and keying features to prevent misalignment and mismating with the receptacle. A positive locking mechanism provides a secure connection with the mating receptacle and prevents accidental unmating caused by excessive shock or vibration. An audible click indicates that the connector is fully mated. For a secure connection to the PCB versions of these Mini-Fit Junior PCB headers are available with snap-in plastic PCB peg locks. Versions are also available with PCB mounting flanges. These Mini-Fit Junior 4.2 mm PCB headers are available with a UL94V-0 or UL94V-2 housing material and with a range of contact configurations and contact platings

Mini-Fit Junior power connectors are ideal for use in high current, high density wire to wire and wire to board applications that require design flexibility. Applications include consumer white goods, office equipment, industrial automation equipment, industrial networks, rack-mount servers, routers and switches.

Use this plug housing from Molex with male connectors to protect your wire-to-board connections. It uses highly conductive tin-plated brass contacts for reliability to keep your system working efficiently. By holding up to four contacts in one component, the unit organises connections for easy identification. As it has two contact rows, this is an ideal choice for improving the packing density of smaller boards.

• 9A current rating per contact provides efficient data and power connections
• Durable nylon construction protects against impact damage
• Straight orientation makes for easy mating
• Polarised contacts prevent incorrect connections and improve reliability

• Sensing equipment
• Manufacturing industry
• Control systems
• Computer displays

Yes, you can. The plug is designed to lock its contacts in place once mated with a female receptacle, preventing disruption to your connections from vibrations caused by moving machinery.
