Flat ribbon RS-232 cable DELOCK 9-pin female header to D-Sub 9-pin male with nuts, 30 cm, black/grey

DELOCK flat ribbon RS-232 cable with a 9-pin female header on one end and a D-Sub 9-pin male connector with fastening nuts on the other. The cable is 30 cm long and comes in black/grey. It is designed for serial RS-232 connections between PC or embedded boards and D-Sub equipment, suitable for prototyping, internal wiring and compact installations where a low-profile ribbon cable and a secure D-Sub connection are required.

Advantages

The flat ribbon construction keeps conductors aligned and organised for easy routing in tight spaces. The 9-pin female header allows direct connection to single-pin header footprints on motherboards or embedded controllers, while the D-Sub 9-pin male connector with fastening nuts provides a secure external interface to equipment with a standard serial port. AWG 28 wire size is suitable for typical RS-232 signal levels and short-distance data transfer. Colour coding (black/grey) helps with visual identification during installation.

Suitable for

• Connecting embedded boards or PC pin headers to external D-Sub RS-232 devices
• Prototyping and internal wiring inside desktop enclosures or industrial housings
• Short-distance serial communication with printers, modems or control equipment
• Compact installations where a flat ribbon cable simplifies routing

Key specifications

• Cable type: flat ribbon RS-232
• Connector A: 9-pin female header (single pin, straight)
• Connector B: D-Sub 9-pin male with fastening nuts
• Cable length: 30 cm
• Wire gauge: AWG 28
• Colour: black/grey

How to use

Align the 9-pin female header with the corresponding single-pin header on the PC or embedded board and press gently to seat the connector. Route the flat ribbon cable to the position of the D-Sub port and secure the D-Sub 9-pin male connector to the mating device using the fastening nuts to ensure a stable mechanical connection. Verify pin alignment and RS-232 signal configuration before powering the system. Use this cable for short internal or near-equipment connections to minimise signal degradation.

Usage recommendations

For reliable RS-232 communication, keep cable runs short and avoid routing alongside high-voltage or high-frequency power cables. Ensure the header orientation matches the board footprint before insertion and tighten the D-Sub nuts to prevent accidental disconnection. For longer distances or electrically noisy environments, consider using shielded or higher-specification serial cabling.
