D-SUB extension cable Divers AK 261 EFB 9-pin male/female, 5 m

The D-SUB extension cable Divers AK 261 EFB 9-pin male/female, 5 m is a serial extension cable designed to lengthen RS-232 and other D-sub connections while maintaining the original 1:1 pinout. With a 5 meter flexible lead and standard 9-pin male-to-female housings, this cable connects devices such as industrial controllers, computers, modems and peripherals without altering signal assignments.

Advantages

This Divers AK 261 EFB cable preserves the standard 9-pin Sub-D wiring so no reconfiguration of connected devices is required. The molded connector housings provide mechanical protection and strain relief at both ends, while the 5 m length gives additional reach for flexible equipment placement. The gendered male-to-female pair ensures straightforward plug-and-play extension of existing serial ports.

Suitable for

• Extending RS-232 serial connections between computers and peripherals
• Connecting industrial equipment and controllers over short-to-medium distances
• Lengthening cable runs for modems, measurement instruments and serial consoles
• Temporary or permanent cabling where a direct 1:1 Sub-D extension is required

Key specifications

• Connector configuration: 9-pin Sub-D male to 9-pin Sub-D female
• Cable length: 5.0 m
• Wiring: direct 1:1 pinout (no cross-over)
• Connector style: molded housings with strain relief
• Typical use: RS-232 and serial D-sub interfaces

How to use

Plug the male end of the Divers AK 261 EFB into the female serial port of the source device and connect the female end to the male connector of the target device. Ensure connectors are seated fully and secure any fastening screws to prevent accidental disconnection. Verify serial communication settings (baud rate, parity, stop bits) on both devices to match the original configuration before data transfer.

Recommendations

For reliable serial communication, avoid running the cable in parallel with high-voltage power lines or strong electromagnetic sources. Use shielded routing where available and secure the cable with cable ties or clips to minimize strain. If the installation environment is exposed to moisture or heavy mechanical wear, consider additional environmental protection or a dedicated industrial-grade cable.
