Serial Cable EFB Elektronik EK131.3 Beige 3m D-Sub 9

The EFB Elektronik EK131.3 Beige 3m D-Sub 9 is a serial cable designed for stable RS-232 connections between devices that use a 9-pin D-Sub interface. With a 3-meter length and a neutral beige jacket, the cable provides convenient reach for desktop or rack-mounted setups while blending into professional and office environments. The construction focuses on consistent data transmission and physical durability for routine use.

Advantages

This serial cable offers reliable signal integrity for serial communications, supported by a robust connector design and practical cable length. The beige outer jacket gives a discreet appearance suitable for mixed equipment environments. Its 9-pin D-Sub connector is compatible with standard serial ports, and the cable is built to withstand repeated connections and standard handling during installation and maintenance.

Suitable for

• Connecting PCs, routers, switches or industrial controllers with RS-232 ports
• Serial console access and device configuration tasks
• Office and laboratory setups where a moderate cable length is required
• Legacy equipment integration and point-to-point serial links

Key specifications

• Connector type: D-Sub 9-pin (male/female configuration depending on model)
• Cable length: 3 meters
• Color: Beige
• Application: RS-232 serial communication
• Construction: Insulated multi-conductor cable with molded or crimped D-Sub housings

How to use

Identify the serial ports on the devices to be connected and align the D-Sub 9 connector with the corresponding port. Secure the connector using the thumbscrews or fastening mechanism to ensure a stable mechanical and electrical connection. Route the cable to avoid sharp bends and sources of strong electromagnetic interference. After connection, verify communication using the device’s terminal software or configuration utilities and adjust serial settings such as baud rate, parity, data bits, and stop bits as required by the equipment.

Recommendations

For consistent performance, avoid running the cable alongside high-voltage power lines or noisy power supplies. When used in industrial environments, protect exposed runs with conduit or cable management to reduce mechanical stress. Inspect connector contacts periodically and replace the cable if outer insulation or connector housings show visible wear.
