Cable serie EFB Elektronik DSub 9 3 m

The EFB Elektronik DSub 9 serial cable (EK143.3) is a 3 m beige shielded cable with D-Sub 9 connectors designed for reliable serial data transmission. It supports standard RS‑232 wiring and is compatible with devices that use a DSub 9 serial interface, providing a flexible connection for modems, routers, industrial controllers and other serial equipment.

Advantages

The cable is shielded to reduce electromagnetic interference and improve signal integrity over the 3 m length. Connectors are mounted and pinned in a standard DSub 9 layout to ensure compatibility with common serial ports. The beige jacket offers a neutral appearance suitable for office and industrial environments while maintaining mechanical flexibility for easy routing.

Suitable for

• Connecting computers or laptops to serial devices with DSub 9 ports
• Linking modems, POS systems, routers and industrial controllers
• Serial communication tasks such as configuration, data logging and diagnostics

How to use

Connect the DSub 9 connectors to the serial ports of the two devices you want to link, ensuring the pins align with the receiving connectors. Secure any fastening screws if present to prevent accidental disconnection. Verify serial port settings (baud rate, parity, data bits, stop bits) on both devices before starting communication. When removing the cable, gently unscrew the connectors rather than pulling on the cable jacket.

Recommendations

For optimal performance, route the cable away from high‑power lines and strong electromagnetic sources. Use appropriate cable strain relief or cable ties to avoid excessive bending near the connectors. Confirm pinout compatibility with the connected devices if nonstandard wiring is required.
