Assemble DB and HD connectors to replace worn out connectors.

Shielded connectors prevent electromagnetic interference.

Connectors with a terminal block wire connection have a contact point inside each hole to create a connection without the need for solder or crimping tools.

Connectors with wire leads come with cable already attached. Each wire lead is a separate color for easy identification and they are labeled with the pin that they are connected to. Those with DB9, DB15, and DB25 connections are RS-232, so they transmit data between computers and equipment. The thumb screws on these connectors have slots so they can be tightened with a screwdriver in tight spaces.

90° elbow connectors sit flush against equipment to fit in tight spaces.

Crimpers (sold separately) are required for wire installation for crimp-on connectors. They ratchet to ensure the correct pressure is applied to every crimp.

Use extraction tools (sold separately) to remove the pins after crimping.

Washdown D-Sub Connectors

Designed to withstand washdown and outdoor environments, these connectors have a seal to block out water and debris. They also have solder cup terminals that hold wire leads in place when you’re soldering them, creating more secure connections than standard solder terminals.

Backshell connectors have an adjustable locknut with a rubber gasket to seal connections on a range of cable diameters.

Use optional covers on panel-mount connectors to protect them from water and debris when they’re not in use.

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.

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

Extraction tools release the locking mechanism on sleeves to remove them from housings.
