Serial Cable EFB Elektronik EK137.5 Beige 5m D-Sub 25

The EFB Elektronik EK137.5 Beige 5m D-Sub 25 serial cable provides a straightforward wired connection between devices that use a D-Sub 25 interface. With a five-metre length and a neutral beige jacket, the cable is intended for desk, industrial or office environments where a reliable serial link is required for data transfer, configuration or control signals. The construction focuses on consistent signal transmission over a standard RS-232/parallel-style connection while keeping installation simple and unobtrusive.

Advantages

This serial cable offers a durable outer jacket and a fixed D-Sub 25 connector designed to maintain a stable physical and electrical connection. The five-metre length reduces the need for extension adaptors while allowing flexible placement of equipment. The neutral beige color blends into many installations, and the cable’s manufactured tolerances help ensure predictable performance for legacy and industrial equipment that rely on D-Sub 25 connections.

Suitable for

• Connecting computers, printers or instrumentation with D-Sub 25 ports
• Serial data transfer and device configuration
• Industrial control systems and legacy equipment integration
• Office setups where extended reach without clutter is required

Key specifications

• Cable length: 5 metres
• Connector type: D-Sub 25 (male/female as applicable for serial connections)
• Colour: Beige
• Intended interface: D-Sub 25 serial connections (commonly used with RS-232 compatible devices)
• Cable usage: Data transmission and signal lines for serial/parallel-style equipment

How to use

Connect the D-Sub 25 connector to the corresponding port on each device, ensuring correct orientation and secure engagement of any fastening screws or clips. Route the cable to avoid sharp bends and mechanical strain; secure using cable ties or clips if necessary to prevent movement. After connection, verify communication settings (baud rate, parity, stop bits) in the connected devices or host system to match the link requirements. If required by the equipment, use appropriate adapters or null-modem wiring to match pinouts between devices.

Recommendations

For reliable long-term performance, avoid running the cable in parallel with high-voltage power lines to minimize interference. Inspect connectors periodically for wear or corrosion and replace the cable if physical damage is observed. When integrating legacy devices, confirm signal levels and pinouts before commissioning to prevent communication issues.
