Molex Mini-Fit Jr. Series Right Angle Through Hole PCB Header, 4 Contact(s), 4.2mm Pitch, 2 Row(s), Shrouded

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 robust header from Molex to establish reliable connections to PCBs. It's through-hole mounted to the circuit boards and serves as a receptacle to let adapters connect easily for power signal transmission. Tin-plated brass contacts are highly conductive for a stable link as well as being corrosion-resistant, so you can rely on this header for durability. Nylon housing provides insulation to protect you from electric shocks. Fully isolated terminals prevent damage from dust and mishandling, making the unit suitable for use in harsh environments.
