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.
Insertion tools (sold separately) are helpful for assembling small wires.
Extraction tools (sold separately) release the locking mechanism on sleeves to remove them from housings.
Crimpers (sold separately) are required to install wires.
