Sarjakaapeli RS-232 DeLOCK 87472 2 m naaras-naaras

This Serial Cable RS-232 DeLOCK 87472 is a full-handshake null modem cable with RTS/CTS and DTR/DSR flow control. It connects two RS-232 devices directly and can optionally supply power via the RI line. The cable uses compact mini D-Sub 9 (D-Sub 9 female) connectors and a slim plug housing, making it suitable where multiple RS-232 ports are placed close together.

Advantages

The full handshake wiring (RTS/CTS and DTR/DSR) ensures reliable hardware flow control for stable serial communication. A 2 m cable length provides flexibility for device placement while a 5 mm cable diameter and narrow D-Sub 9 housing allow use in tight spaces. The female-to-female configuration is suitable for direct device-to-device connections without a host.

Suitable for

• Connecting two RS-232 devices directly (null modem)
• Industrial equipment and instrumentation with DB-9 ports
• Legacy computers, PLCs, routers or modems requiring serial links
• Environments where compact connector housings are needed

Key specifications

• Manufacturer: DELOCK
• Model / MPN: 87472
• EAN: 4043619874729
• Connector type: D-Sub 9 female to D-Sub 9 female (null modem wiring)

How to use

Connect the female D-Sub 9 connectors to the corresponding DB-9 ports on each device. Ensure both devices are powered and configured for RS-232 communication with matching baud rate and parity settings. If power over the RI line is required, verify device compatibility before use. Tighten the connector screws to secure the connection and avoid signal issues.

Recommendations

Use this cable for short to medium serial connections up to 2 m; avoid routing near high-voltage or high-frequency cables to minimise interference. Check device manuals for RI line power limitations before relying on it to supply power.
