DB9

DB50

HD15

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.

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.

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.

USB Cords

Connect devices such as computers, printers, and mobile devices. The higher the USB standard, the faster cords can transmit data. These cords are backward compatible, so they work with cords and connectors that meet the same or lower USB standard.

Data cords move data between devices.

Double-shielded cords block signal interference from nearby equipment and devices.

Continuous-Flex Data Communication Cable

Use For: Automation, Continuous Motion, Data, Interference Shielding
Continuous Flex
Temperature Range:
PVC Plastic Insulation: 25° to 155° F
TPE Rubber Insulation: -30° to 210° F

Often used to send signal and data to order pickers and cranes, this cable withstands continuous motion applications without degrading data or signal transmission. In addition to a layer of braid shielding, it has twisted pairs of wires that cancel signal interference from multiple transmission lines. Suitable for clean rooms, they release minimal particles into the air. All are CE marked as compliant with European health, safety, and environmental standards.

Cable with PVC insulation is for indoor use.

Cable with TPE rubber insulation is for outdoor use and resists coolant, oil, and UV light.
