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.
