Multipurpose Build-Your-Own Latching Connectors

Combine power, USB, computer, and compressed air inserts to build a connector that sends signal, power, and data. A complete connector requires a hood, a base, two frames, and a male and female insert for each slot in the frame. The frames fit into the hood and base, and the inserts snap into the frame. Select components based on the number of slots needed. Once assembled, connectors are rated NEMA 4X, 12, and IP65 for protection against dirt, washdowns, and oil/coolant dripping.

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 positioners (sold separately) with crimpers to hold pins and sleeves at the correct height while crimping.

Insertion/Extraction tools (sold separately) make it easier to install DB25 inserts.

DB25

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.

D-Sub Cords

Connect computers, monitors, printers, and other devices with DB connections.

RS-232 cords transmit data between a modem and another device, such as a computer.

Parallel cords connect a computer to a printer.

Shielded cords have foil to prevent signal interference from nearby devices. Use them in settings with low to moderate signal interference, such as labs, storage facilities, and offices.

Double-shielded cords have braid and foil for better protection against signal interference than shielded cords. However, the extra shielding adds diameter and reduces flexibility. They’re used in steel mills, machine tool plants, and other heavy processing facilities.

Cords with reversible mounting hardware have removable thumb screws to enable a wider range of mounting options than other cords. Mount them to ports and adapters, as well as directly into panels.
