    Configure a connector for your application—combine male and female inserts with a base and a hood. Select components based on the number of poles needed. To protect connections while maintaining access, the base and hood latch together securely, yet can be quickly detached for equipment repair or replacement. Once assembled, these connectors are rated NEMA 4X, 12, and IP65 for protection against corrosion, washdowns, dirt, oil/coolant dripping, and water projected from a nozzle.

    M23 Connectors

    Reliably power or control servomotors, controllers, drives, and other devices where high power can interfere with control signals. You can find these connectors in high-vibration environments, such as near automated equipment and assembly lines.
    When mating connectors, the gender and pole layout must be opposite. Poles are numbered on the face of the connector.

    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
    Image of Product. Front orientation. Molex Connectors. Build-Your-Own Molex Circuit Board Connectors with Locking Tab, 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.

    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.

    Build-Your-Own Amphenol Circuit Board Connectors

    Attach wires to your circuit board with these Amphenol PV connectors. They push together, so they're easy to connect and disconnect yet still give you a strong, secure hold. Even after repeated use, they won’t lose their connection strength. First designed for use in solar power—the PV stands for photovoltaic—they’re also used in equipment ranging from small electronics to industrial robots.
    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.
