39-28-1063, Molex Mini-Fit Jr. Series Straight Through Hole PCB Header, 6 Contact(s), 4.2mm Pitch, 2 Row(s), Shrouded

Mini-Fit Junior 4.2mm PCB Header Connectors

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

Features and Benefits

• 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

Molex Mini-Fit Jr Straight PCB Header, 6 Way, 2 Rows - 5566 Series - 39-28-1063

Join up to six wires to a PCB (printed circuit board) using this straight PCB header from Molex. It has a compact 4.2mm pitch for use in tight spaces and can handle up to 9A of current per contact, making it a practical solution for medium-range power transfers. The six terminals are arranged in two rows to keep your connections organised and compact. Each contact is fully isolated to prevent electrical interference, ensuring more reliable transmission.

Features & Benefits

• Deep terminal design shields contacts from mishandling to prevent damage
• Designed for solder termination to ensure a secure connection in high-vibration applications
• Housing clicks when successfully locked in place to confirm a secure connection
• Polarised and keyed terminals ensure housing is mated correctly for optimal performance

Applications

• Office equipment
• Industrial automation equipment
• Rack-mount servers
• Routers and switches

What is this PCB header made of?

This PCB header is made of a tough nylon material that's resistant to wear and chemicals. Its contacts are made of corrosion-resistant tin-plated brass, making it a good choice for use in harsh industrial environments.
