Accessories and Replacements for D-Sub Connectors

Use extraction tools to remove the pins after crimping.

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

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.
