RS232 serial cable DB9 9-pin male-female (extension)
Connecting a PLC, a machine tool, or an old instrument with a serial port is still common in workshops — but the cable is often missing. This male-to-female DB9 RS232 cable connects or extends the serial link between a PC and the equipment.

Product details
In practice, this cable remains essential in industrial and networking applications. Wired pin-to-pin (1-1 to 9-9), it extends or establishes a serial link between a computer and equipment such as a PLC, CNC machine, measuring instrument, or network equipment console. Its HDPE insulation minimizes interference over length. No more too-short serial connections; enjoy a stable connection, provided you verify the pinout of your equipment.
Compatibility and uses
This cable connects two 9-pin DB9 connectors, one male and one female, using straight-through wiring (pin to pin). It is used to connect or extend a PC to an RS232 serial port device: PLC, machine tool (CNC), measuring instrument, network equipment console, or legacy peripheral. It is a straight extension cable, not a null-modem cable (which crosses the wires). Available in 1.5, 3, 5, or 10 m lengths.
