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.

This robust header from Molex provides a mating channel so you can link connectors to your printed circuit boards (PCBs). Thanks to a through-hole mounting method, it's simple to set up and achieves a firm hold on the board. This makes it a suitable choice for systems with high mechanical stress. The unit features conductive brass contacts for a reliable electrical connection, while tin plating makes them corrosion-resistant. Right-angle orientation means it projects out of the connection point, making it practical for use in tight spots. Headers like this one are typically used in the medical and consumer electronics industries.

• Nylon body material for impact resistance and insulation from electric shocks
• Light weight of 2.24g for easy handling
