Cable alargador D-SUB ShiverPeaks AK 2303 9 polos, 3 m

D‑SUB Extension ShiverPeaks AK 2303 9‑pin connector cable, 3 m is a 3‑metre serial extension cable with a straight 9‑pin D‑SUB interface engineered to extend RS‑232/serial connections. The cable provides a continuation of an existing DB9 link using a male 9‑pin plug on one end and a female 9‑pin socket on the other, allowing continuation of signals between devices without changing connector types. It is intended for reliable signal extension in environments where standard 9‑pin Sub‑D connectivity is required.

Advantages

The extension cable features a full‑size 9‑pin Sub‑D interface that preserves pin assignments and signal integrity over a 3 m length. The molded connector housings reduce strain at the terminations and provide consistent mechanical protection. The straight male‑to‑female configuration simplifies connecting modems, serial peripherals, and legacy equipment without adapters. The neutral construction supports common RS‑232 signalling and is compatible with a wide range of devices that use a standard DB9 connector.

Suitable for

• Extending RS‑232 serial links between computers and modems
• Connecting industrial controllers and PLCs to operator terminals or diagnostic tools
• Linking serial printers, barcode scanners or labelers with DB9 interfaces
• Maintaining connections to legacy equipment that uses 9‑pin Sub‑D connectors

Key specifications

• Connector type: 9‑pin Sub‑D male to 9‑pin Sub‑D female
• Cable length: 3.0 metres
• Connector housing: molded for strain relief and mechanical protection
• Intended signal standard: RS‑232/serial
• Configuration: straight, one‑to‑one pin mapping (no gender change or pin conversion)

How to use

Connect the male 9‑pin plug to the female serial port on the source device and plug the female 9‑pin socket onto the male serial port of the destination device. Ensure both devices are powered off or follow hot‑swap guidelines provided by the device manufacturers before connecting if required. Once connected, verify serial communication settings (baud rate, parity, stop bits) in the host and peripheral devices to match the existing RS‑232 configuration. Route the cable to avoid sharp bends, heavy compression, or sources of electrical noise.

Recommendations

For best performance, keep the cable run within 3 m as specified and avoid routing alongside high‑voltage power lines or motors. Use ferrite cores or shielded routing if the environment has elevated electromagnetic interference. If you require longer runs or signal buffering, consider using repeaters or RS‑232 to RS‑422/RS‑485 converters appropriate for your application.
