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.

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

Shielded—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—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.
