Cavo seriale DELOCK 86909, D-Sub 25 poli su D-Sub 9 poli, beige, 0,5 m

DELOCK 86909 is a 0.5 m serial adapter cable with a 25-pin D-Sub connector on one end and a 9-pin D-Sub connector on the other. The cable is beige and intended to provide a reliable physical connection between legacy RS-232 serial equipment and devices with a 9-pin serial port. It supports standard signal lines used in serial communication and is suitable for short interconnects in desktop, industrial, or lab environments.

Advantages

The adapter cable offers a compact, fixed-length solution for converting between a D-Sub 25-pin interface and a D-Sub 9-pin interface without the need for active electronics. Its shielded connectors and molded strain reliefs help maintain signal integrity and reduce mechanical wear at connection points. The 0.5 m length minimizes excess cable clutter while providing enough reach for rack-mounted or bench setups.

Suitable for

• Connecting industrial controllers and PLCs to 9-pin serial ports
• Linking legacy modems, instrumentation, or data loggers to computers or terminals
• Interfacing RS-232 serial devices during maintenance, testing, or configuration
• Short-distance serial cabling in workshops, labs, or control cabinets

Key specifications

• Connector A: D-Sub 25-pin (male or female depending on device orientation)
• Connector B: D-Sub 9-pin (male or female depending on device orientation)
• Cable length: 0.5 m
• Color: beige
• Intended interface: RS-232 serial communication
• Construction: molded connectors with strain relief

How to use

Inspect both device ports to confirm the correct connector genders and align the D-Sub shell before mating. Gently insert the 25-pin connector into the corresponding device port and secure any thumbscrews if present, then connect the 9-pin end to the receiving device and fasten its screws. Ensure both devices are powered and configured for the same serial parameters (baud rate, parity, data bits, stop bits, and flow control) before initiating communication. Avoid excessive bending near the connectors to preserve cable life.

Recommendations

For reliable serial communication, use this cable for short runs and in environments where standard RS-232 levels are supported. Keep the cable away from high-voltage or high-frequency sources to reduce interference. If longer distances or signal conversion (e.g., RS-232 to USB or RS-485) are required, select an appropriate active adapter or repeater.
