InLine serial cable DB25 male to DB25 female 20 m direct connection

The InLine serial cable DB25 male to DB25 female 20 m direct connection is designed for reliable data transmission over extended distances in professional and technical environments. Measuring 20 meters in length, this beige cable features a DB25 male connector on one end and a DB25 female connector on the other, utilizing a straightforward 1:1 direct pinout configuration for seamless integration into existing networks.

Advantages

This serial extension cable provides a direct and unchanged signal transmission path, eliminating the need for complex configurations or additional adapters. The moulded connectors offer high mechanical stability, protecting internal contact points from physical strain and reducing interference caused by movement. Its versatile design supports multiple standard interfaces, making it a dependable choice for both permanent infrastructure installations and temporary setups during maintenance.

Suitable for

• Extending existing RS232, RS422, or RS485 serial communication links
• Connecting legacy peripheral devices and industrial control systems
• Technical setups requiring a 20-meter reach between equipment

When it may not be suitable

This cable is not designed for high-speed modern consumer networking tasks such as Ethernet data transfer or video streaming. Devices that do not utilize a standard 25-pin Sub-D serial interface will require separate conversion hardware.

Key specifications

• Cable length: 20 m
• Connector 1: DB25 male (Sub-D 25-pin)
• Connector 2: DB25 female (Sub-D 25-pin)
• Pin assignment: 1:1 direct connection
• Supported interfaces: RS232, RS422, RS485
• Colour: Beige

How to use

To use the InLine serial cable, ensure that both connected devices are powered off to prevent potential electrical surges. Insert the DB25 male connector into the corresponding serial port of the host system or extension source, and attach the DB25 female connector to the peripheral device or target cable end. Fasten any securing screws on the connectors to maintain a stable mechanical connection. Once securely attached, power on your equipment for immediate signal transmission.

What to consider before purchase

• Verify that your hardware utilizes standard DB25 serial ports rather than smaller DB9 connections
• Confirm that a 20-meter cable length is appropriate for your spatial layout without causing excessive cable slack
• Check if your devices require a 1:1 direct pinout configuration or a null-modem crossover setup

Ensure the cable is routed away from high-voltage power lines and sharp edges to prevent signal interference and physical wear during long-term operation.
