Modem Cable ROLINE DB9 F - DB25 M 3.0 m

Modem Cable ROLINE DB9 F - DB25 M 3.0 m connects devices with a DB9 female and a DB25 male serial interface. This 3.0 m grey cable is designed for reliable serial data transmission between a PC and a modem or other devices with matching connectors. The connector housings are moulded with a special plastic to reduce strain and prevent cable breaks, and the contacts are bronze with gold plating for stable connections.

Advantages

The cable provides very good screening to minimise data loss and electromagnetic interference. Hand locking screws ensure secure mechanical connection, while moulded connector casings offer optimal strain relief to extend cable lifespan. Gold-plated bronze contacts improve conductivity and resist corrosion for consistent signal quality.

Suitable for

• Connecting a PC serial port (DB9) to a modem or serial device with DB25
• Legacy serial communications and equipment requiring DB25 connectors
• Data transmission where EMI shielding and secure mechanical connection are important

Key specifications

• Connector A: DB9 female (9-pin)
• Connector B: DB25 male (25-pin)
• Length: 3.0 m
• Contact material: bronze with gold plating
• Connector casing: moulded plastic with strain relief
• Shielding: high-quality screening to reduce electromagnetic interference
• Locking: hand screws

How to use

Align the DB9 female connector with the DB9 serial port on the PC and the DB25 male connector with the modem or target device. Push connectors gently until they seat, then tighten the hand locking screws by hand to secure the connection. Route the cable to avoid sharp bends and mechanical stress on the moulded connector areas.

Usage recommendations

For best performance, avoid running the cable in parallel with high-voltage power lines and keep it away from strong electromagnetic sources. Inspect connectors for damage before use and do not force connectors into incompatible ports.
