InLine serial cable DB9 female / female direct 5m

This 5-metre InLine serial cable provides a direct DB9 female-to-female connection for devices equipped with 9-pin Sub D connectors. Designed for straightforward point-to-point serial communication, the cable is suitable for data transfer and control signals between computers, industrial equipment, legacy peripherals and serial-enabled instruments. The beige jacket offers neutral appearance and easy identification in cable bundles.

Advantages

The InLine DB9 female/female direct cable offers reliable signal continuity over a 5 m length and a standard 9-pin Sub D interface compatible with many serial RS-232 devices. Its fixed female-to-female wiring eliminates the need for adapters when connecting two male-equipped devices or extension of existing serial leads. The cable’s jacket provides basic protection and the neutral beige colour helps with visual organisation in mixed cable environments.

Suitable for

• Connecting RS-232 serial ports on computers, terminals and routers
• Linking industrial controllers, PLCs and measurement instruments with 9-pin Sub D connectors
• Extending or joining existing serial leads in lab and workshop settings
• Interfacing legacy peripherals such as modems, barcode scanners and printers

Key specifications

• Connector type: DB9 (9-pin Sub D) female to female
• Cable length: 5 metres
• Colour: Beige
• Connection type: Direct serial wiring for standard RS-232 signalling
• Use environment: Indoor data and control cabling

How to use

Align each DB9 female connector with the corresponding 9-pin male port and gently insert until secure; fasten any thumbscrews if present to ensure a stable mechanical connection. Use the cable to connect serial-enabled devices for data exchange, configuration or control tasks. Avoid sharp bends and keep the cable away from high-voltage or high-frequency sources to minimise interference. If connecting through multiple segments, verify signal integrity and correct pin assignments for your specific equipment before operation.

Recommendations

For optimal performance, route the cable away from mains power and large motors to reduce electromagnetic interference, maintain bend radius larger than the cable diameter, and check device documentation for required RS-232 settings such as baud rate, parity and handshake lines.
