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

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.

Keep your electrical wires securely connected to your PCB (printed circuit board) with this Molex straight PCB header. The device can accommodate up to eight wires for versatile use, and the straight body orientation ensures your wires are clearly laid out for ease of organisation and identification. It has a high voltage rating of 600V for use in high-powered applications. Thanks to its tin-plated brass contacts, the unit is resistant to corrosion for reliable, long-lasting performance in harsh environments. This header is shrouded to reduce electrical interference and ensure high-quality transmission.

• Wide operating temperature range of -40°C to +105°C for use in extreme environments
• Terminals are polarised and keyed to prevent mismating
• Positive locking mechanism keeps wires securely in place, even in the event of heavy vibrations
• Durability of up to 30 mating cycles for long-lasting use
• Two-row design keeps wires organised while occupying less space than a single-row header

• Industrial networks
• Harness manufacturers
• Non-sealed applications
• Electronic control modules

Yes, the nylon material of this PCB header is flame-retardant, so it won't promote the spread of flames in the event of a fire.
