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

• Can handle Up to 9A current per circuit
• Fully isolated terminals
• Scoop-proof housings to prevent contact damage
• Polarization and keying to prevent mismating

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.

Need a way to establish a secure link between wiring and a circuit board? This PCB header from Molex does the job. It's a space-saving option with a total of 10 contacts arranged over two rows, which lets you send power and data signals to multiple circuits. The fully isolated terminals have a 4.2mm pitch to cut the risk of arcing out of the equation. The header's nylon body performs double duty by resisting impact and acting as an electrical insulator.

• Brass contact pins ensure a reliable electrical connection
• Positive locking mechanism prevents accidental disconnection due to vibrations
• 9A maximum current per contact for high-powered applications
• Audible click when properly connected to avoid incorrect mating

• Security systems
• Data centres
• Consumer robotics

You can be sure of a precise fit with female terminals in the Mini-Fit series.
