Serial Cable EFB Elektronik EK165.3 Beige 3 m D-Sub 25

The EFB Elektronik EK165.3 serial cable is a 3-meter cable with a D-Sub 25 connector in a beige finish. Designed for reliable RS-232 style connections and other equipment that use a 25-pin D-Sub interface, the cable offers a moderate length for flexible placement of devices in offices, workshops, and home installations. The neutral beige jacket blends with many environments while maintaining a functional and unobtrusive appearance.

Advantages

This serial cable provides stable data transmission for devices with a D-Sub 25 interface and reduces the need for immediate proximity between connected equipment thanks to its 3 m length. The molded connectors and jacket deliver a consistent physical connection and help protect the conductors from everyday wear. The straightforward design makes it compatible with a wide range of legacy and industrial devices without requiring additional adapters.

Suitable for

• Connecting serial printers and older computer peripherals
• Linking industrial controllers, PLCs, and measurement instruments
• Integrating networking equipment or serial converters with D-Sub 25 ports
• Use in office, laboratory, workshop, and point-of-sale setups

Key specifications

• Cable length: 3 m
• Connector type: D-Sub 25 (25-pin)
• Colour: Beige
• Intended signal type: Serial/parallel-style D-Sub connections (commonly RS-232 and compatible interfaces)
• Construction: Molded connectors with insulated jacket

How to use

Connect the D-Sub 25 connector to the matching port on your device, ensuring the pins align correctly before seating the connector. Secure the connector using any captive screws or fastening mechanism present on the device to maintain a reliable physical connection. Route the cable to avoid sharp bends and areas of potential mechanical damage; leave some slack to prevent strain on ports. If necessary, power down equipment before connecting or disconnecting to prevent data errors or voltage transients on legacy interfaces.

Usage recommendations

For best performance, avoid running the serial cable in parallel with high-voltage power lines or noisy data cables. Use short cable runs where possible for critical signals, and inspect connectors periodically for bent pins or corrosion to ensure long-term reliability.
