EFB Elektronik K5139.5 Serial Cable Beige 5 m D-Sub

The EFB Elektronik K5139.5 Beige 5 m D-Sub serial cable provides a straightforward wired connection between devices equipped with D-Sub serial ports. With a 5 meter length and a neutral beige jacket, this cable is intended for reliable point-to-point data transfer in both home and professional environments. The cable construction supports standard serial communication protocols and is designed for continuous use where a stable physical connection is required.

Advantages

This 5 m D-Sub serial cable offers consistent signal transmission and a flexible outer sheath that simplifies routing through workspaces. The beige color makes it unobtrusive in office or equipment racks, while the connector design ensures secure mating with compatible D-Sub ports. The cable’s length balances reach and signal integrity for common serial setups.

Suitable for

• Connecting computers, PLCs, routers and legacy equipment with D-Sub serial ports
• Industrial control systems and machinery that use RS-232 or similar serial protocols
• Point-to-point data transfer in offices, server rooms and workshops
• Temporary test and diagnostic setups requiring a reliable 5 m connection

Key specifications

• Cable length: 5 metres
• Connector type: D-Sub serial connector
• Color: beige
• Usage: designed for serial data transmission (point-to-point)
• Construction: flexible outer jacket suitable for indoor installations

How to use

Ensure both devices are powered off before connecting the D-Sub connectors to prevent data errors during hot plugging. Align the connector pins with the port and secure any fastening screws to maintain a stable physical connection. After connection, power on the devices and verify communication settings such as baud rate, parity, data bits and stop bits to match the connected equipment. For temporary tests, connect one end to the host device and the other to the peripheral or diagnostic tool and confirm successful data exchange.

Recommendations

Route the cable away from high-voltage power lines and sources of strong electromagnetic interference to preserve signal integrity. Avoid sharp bends and kinks; allow gentle curves with a radius at least five times the cable diameter. For permanent installations, fasten the cable with non-compressive clips and avoid excessive tensile force on the connectors.
