RS232 Cable ROLINE M - M 4.5 m

The ROLINE RS232 Cable M - M 4.5 m is a grey DB-25 (D-Sub 25) cable with male connectors on both ends, designed to connect RS232-capable devices such as a computer to a switchbox or two serial interfaces. The cable provides a straight 1:1 wiring of all 25 pins and a shield connection tied to the foil screen and both connectors for reliable signal integrity over a 4.5 m length.

Advantages

All 25 lines are wired one-to-one, ensuring full pin compatibility for DB-25 serial connections. The molded connector housings use a special plastic for improved strain relief, and hand locking screws secure a stable mechanical connection. The cable features very good screening to reduce electromagnetic interference and minimize data loss. Contacts are bronze with gold plating to provide consistent electrical contact and corrosion resistance.

Suitable for

• Connecting a computer to a switchbox with DB-25 RS232 ports
• Linking two devices with serial DB-25 interfaces
• Industrial and office RS232 data or control connections up to 4.5 m

Key specifications

• Connector type: 2 × 25‑pole D‑Sub male (DB‑25 M - M)
• Cable length: 4.5 m
• Wiring: 25 lines connected 1:1
• Shielding: foil screen with shield drain tied to both connectors
• Connector housing: molded with special plastic for strain relief
• Contact material: bronze with gold plating
• Locking: manual thumb screws

How to use

Align the DB‑25 male connectors with the corresponding DB‑25 female ports on the devices, insert gently and secure each connector using the hand locking screws. Ensure both devices are powered off or set to the appropriate communication settings before establishing the connection. After connecting, configure serial port parameters (baud rate, parity, data bits, stop bits) on both devices as required by your application.

Usage recommendations

For best results, route the cable away from strong sources of electromagnetic noise and avoid sharp bends or kinks. Inspect connector screws and contact condition periodically; replace the cable if the shielding or contacts show signs of damage.
