## Long description

The EFB Elektronik EK165.5 Beige 5m D-Sub 25 is a 5-metre serial cable designed for reliable RS-232 style connections using a 25-pin D-Sub connector. Its neutral beige jacket suits office, laboratory and industrial environments where a discreet, standard serial connection is required. The cable delivers stable data transmission between devices with D-Sub 25 interfaces and is built to withstand regular use while maintaining signal integrity over its length.
Advantages
This 5 m D-Sub 25 cable provides consistent serial communication performance and is manufactured with materials aimed at durability and stable contact resistance. The neutral beige colour helps the cable blend into mixed equipment setups. Its length offers flexibility in device placement without compromising signal quality for typical serial data rates, and the standard D-Sub 25 connector ensures broad compatibility with legacy and current equipment using 25-pin interfaces.

Key specifications
 Connector type: 25-pin D-Sub (D-Sub 25)
 Length: 5 metres
 Colour: Beige
 Cable function: Serial data transmission (RS-232 style wiring)
 Construction: Shielded multi-conductor cable with molded connector housings
How to use
Connect one end of the D-Sub 25 cable to the serial port of the source device and the other end to the target device's 25-pin D-Sub connector, ensuring secure seating and, if present, fastening any connector screws to prevent accidental disconnection. Confirm that both devices share compatible serial settings (baud rate, parity, stop bits and flow control) before initiating communication. Route the cable to avoid sharp bends and sources of strong electromagnetic interference to maintain signal quality.
Usage recommendations
For best results, avoid routing the cable parallel to high-voltage power lines and keep connections dry and free from mechanical strain; inspect connector pins periodically for cleanliness and secure contact. Use the appropriate serial configuration on your devices to match expected data parameters and consider adding ferrite cores if operation is near known EMI sources.
