Modem cable Triton ROLINE DB9 F to DB25 M 3.0 m, grey

Serial modem cable Triton ROLINE DB9 F to DB25 M, 3.0 m, grey is designed for RS-232 interconnection between devices using a 9‑pin D-Sub female and a 25‑pin D-Sub male connector. The 3.0 m cable provides sufficient reach for desktop and rack environments where legacy modems, serial peripherals or other RS‑232 equipment must be connected. The grey jacket offers neutral aesthetics and easy integration into office or industrial cabling runs.

Advantages

The connector casings are moulded with a special plastic to provide optimal strain relief and reduce the risk of cable breaks at the connector. Very good shielding minimizes electromagnetic interference and helps prevent data loss during serial communication. Hand locking screws secure the connectors without tools, and bronze contacts with gold coating ensure reliable electrical contact and resistance to corrosion.

Suitable for

• Connecting legacy modems to PCs or serial interface cards
• Serial peripherals such as printers, plotters or industrial controllers using DB9/DB25 wiring
• RS‑232 point-to-point links in office, lab or light industrial environments

Key specifications

• Connector 1: 9‑pin D-Sub female (DB9 F)
• Connector 2: 25‑pin D-Sub male (DB25 M)
• Cable length: 3.0 m
• Jacket colour: grey
• Shielding: high-quality screening to reduce electromagnetic interference
• Contacts: bronze with gold coating for corrosion resistance and reliable contact
• Connector strain relief: moulded plastic casing for reduced stress at cable entry
• Fixing: hand locking screws for tool-free secure connection

How to use

Identify the DB9 female and DB25 male ends and align the connectors with the mating ports on your devices. Push the connectors fully onto the ports, then tighten the hand locking screws to secure the connection. Ensure the cable routing avoids sharp bends and high-tension pull points to preserve the moulded strain relief. Verify serial communication parameters on both devices (baud rate, parity, stop bits, flow control) to match the expected RS‑232 settings before transferring data.

Usage recommendations

For stable connections, avoid running the cable parallel to high-voltage power lines or strong RF sources; if necessary, increase separation or use additional shielding. Periodically inspect the connector housings and contacts for signs of wear or corrosion, and replace the cable if any mechanical damage is found. Use the cable in environments compatible with standard RS‑232 equipment and within the physical reach provided by the 3.0 m length.
