Circuit Board Headers

Use these headers to make quick, temporary connections to development boards and other circuit boards when prototyping. Solder the termination contacts directly to your board, and use the mating contacts to transmit power and send signals to your equipment.

Build-Your-Own Molex Circuit Board Connectors with Locking Tab

Connect wires to circuit boards with Molex Mini-Fit push-in connectors. These connectors are easier to detach than Amphenol PV connectors, so they’re often used for prototyping. A complete connector consists of a sleeve housing, sleeves, and a circuit board plug (all sold separately). To assemble these connectors, crimp sleeves onto your wires, then place them inside a sleeve housing. Once you’ve wired the sleeve housing, slide it onto a circuit board plug.

Circuit Board Plugs

Plugs have an alignment key that ensures the plug and housing are mated correctly, which is helpful when you can’t get a good look during installation. A locking tab holds the housing and plug together once they’re mated. To install the plug on your circuit board, push the contacts through the board’s holes and solder them in place. All plugs have gold-plated brass pins, which are more corrosion resistant than tin- or nickel-plated pins, so the electrical connection lasts longer.

Snap-In Pegs—Plugs with snap-in pegs relieve stress on the terminal when plugging and unplugging wires.

Build-Your-Own Molex Circuit Board Connectors

Connect wires to your circuit board with these Molex KK push-in connectors. A good choice for prototyping, they require less force to disassemble than Amphenol PV connectors. However, this means that they are less secure in more demanding applications.

For a complete connection, choose a plug and housing with the number of poles that matches the number of wires you need to connect. You’ll also need one sleeve for each wire.

Circuit Board Plugs

Plugs have a friction clip to securely hold the housing when mated. They also have an alignment key that ensures the plug and housing are mated correctly, which is helpful when you can’t get a good look during installation. To install the plug on your circuit board, push the contacts through the board’s holes and solder them in place. The pins are gold-plated brass, so they resist corrosion better than tin- or nickel-plated pins. This means they’ll have a good, long-lasting electrical connection.
