InLine Serial extension, 9pin male / female, moulded, 1:1 assigned, 3m

Reliable serial signal extension:The extension enables stable expansion of existing RS232, RS422 or RS485 connections between system components with a 9-pin Sub-D interface.
1:1 assigned for direct signal transmission:All pins are connected one-to-one and enable unaltered transmission without cross-wiring.
9-pin Sub-D plug to socket:The assembly with 9-pin plug and 9-pin socket allows easy extension of existing DB9 connections.
Moulded connector design:The moulded connectors support a mechanically stable connection and increase resistance in daily use.
Flexible length options:Available in 2 metres, 3 metres, 5 metres, 7 metres, 10 metres, 15 metres and 20 metres for installations tailored to your needs.

The InLine® serial extension with 9-pin Sub-D plug to 9-pin Sub-D socket is used to extend existing serial interfaces. It is suitable for RS232, RS422 and RS485 connections between peripheral devices, data switches and PC or server systems.
Thanks to the 1:1 pin assignment, all pins are directly connected. There is no cross-wiring. This means that the signal structure of the existing connection remains unchanged.
The moulded connectors support a stable mechanical connection and are designed for regular use. The standardised 9-pin Sub D assembly allows for easy integration into existing installations.
The cable is available in several defined lengths and can be flexibly adapted to different installation requirements.

How to use

Plug the DB9 male end into the serial port of the PC, server, or data switch and connect the DB9 female end to the serial peripheral device. Ensure screws are tightened to secure the connectors. Verify serial port settings (baud rate, parity, stop bits) on both devices to match the peripheral’s requirements before starting communication.

Recommendations

For stable communication, keep cable runs away from high‑voltage power lines and large motors to minimise electromagnetic interference. For distances beyond a few metres or in electrically noisy environments, consider using differential serial interfaces or signal extenders.
