D-Sub Connectors

Straight

DB37

Assemble DB and HD connectors to replace worn out connectors.

Shielded connectors prevent electromagnetic interference.

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.

Circuit Board D-Sub Connectors

Add a D-sub connection to a printed circuit board (PCB). These connectors are often used in applications involving monitoring, control, and communication. All meet UL 94 V-0 flame retardant standards for self-extinguishing if a fire takes place.

90° elbow connectors have board locks to secure connectors against circuit boards for stable soldering

DB37

With a ferrite filter block surrounding their contacts, these connectors control and reduce the electromagnetic (EMI) and radio frequency (RFI) interference traveling through them. They have solder cup terminals that hold wire leads in place when you’re soldering them, helping you create a stable connection.

D-Sub Cords

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

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.
