Cables To Go 52030 DB9 M/F Serial RS232 Extension Cable 6 ft

Six-foot DB9 serial extension

This six-foot cable carries a male DB9 connector on one end and a female DB9 connector on the other, extending an existing RS-232 link without rewiring. It suits installers who need to position legacy peripherals such as industrial controllers, barcode scanners or older modems farther from the host computer. The straight-through pinout preserves every signal line so the connected device behaves exactly as if it were plugged directly into the port.

Shielded copper with molded strain relief

Each conductor is copper and the whole assembly is fully shielded to reject EMI and RFI that can corrupt serial data in electrically noisy environments. Molded connector housings and integrated thumbscrews give a secure, tool-free fit while protecting the solder joints from cable tugging. The extension simply plugs in-line between the host port and the device cable, requiring no drivers, external power or configuration changes.

Reliable signal over longer runs

The shielding and straight-through wiring keep the RS-232 voltage levels intact over the full six-foot span, and the manufacturer notes that chaining extensions can reach up to 50 feet total without signal degradation. This makes the cable practical for permanent rack or cabinet runs where the equipment must sit away from the controlling PC. It is not suited for applications that demand differential signalling or higher baud rates than the RS-232 standard defines.
