Mini-Fit Junior 4.2 mm pitch connector housings form part of the Mini-Fit Junior power connector’s interconnection system. Molex connector housings can be used in applications that require design flexibility. These types of fittings are an essential component that offer protection for the connection it is housing.

• Handle Up to 13A current per circuit, a great solution for high current connectors
• Fully isolated terminals for protection against debris and damage caused by mishandling
• Polarization and keying to prevent mismating ad misalignment
• Positive locking mechanism for secure mating connection prevents accidental unmating caused by excessive shock or vibration
• Audible click for mating confirmation
• Available with a flame retardant UL94V-0 or UL94V-2 housing material
• Accepts standard Mini-Fit and Mini-Fit Plus crimp terminals
• Wire to wire and wire to board applications

Looking for a connector housing that offers flexibility when designing applications? This 4.2mm pitch connector from Molex's Mini-Fit Junior range lets you quickly install secure connections. An audible click confirms successful mating, while the positive locking mechanism helps prevent accidental disconnection due to shock or vibration. It can handle up to 13A of current per circuit, making it ideal for use with high-current connectors. Fully isolated terminals protect the connections from debris and mishandling.

• 20 contacts arranged in two rows let you build compact systems
• Cable mounting offers flexible installation options
• Nylon housing for excellent electrical insulation
• Operating temperature up to +125°C makes it suitable for a tough industrial environments

• Connecting cables to PCBs
• Computer systems
• Electronic devices

A wire housing functions as a receptacle for connectors when they're mounted onto a PCB (printed circuit board). They keep the connectors organised and provide some protection.

Isopropyl alcohol is effective at removing corrosion but it's flammable so must be used with care. An abrasive PCB edge eraser, also known as a cleaning scrub block, is another option.
