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
• Positive locking mechanism for secure mating connection
• Audible click for mating confirmation
• Versions with PCB retention pegs and mounting flanges

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 PCB header from Molex to make secure power and wire-to-board connections. As its tin-plated brass contacts are highly conductive and corrosion-resistant, you can be sure of reliable performance. A current rating of 13A per contact means you can safely use this component in high-powered systems. It's polarised to help prevent incorrect mating and damage to the header. Thanks to a broad operating temperature range of -40°C to +105°C, it's suitable for use in demanding environments.

• Audible click for mating confirmation and to ensure a secure attachment
• Durability of up to 30 mating cycles for long-lasting use
• Right-angle orientation to fit in awkward spaces

• Computers
• Control cabinets
• Electrical engineering

This PCB header is designed for through-hole mounting, ensuring simple and secure installation on your PCB.
