Black Box Serial Extension Cable DB9 EMI/RFI Hoods 51.2 Ohms 8 mm

Serial Extension Cable with EMI/RFI Hoods

This Black Box DB9 extension cable carries all nine pins straight through for reliable serial links. Metal EMI/RFI hoods are removable to allow repinning when a custom pin-out is needed. Heavy-duty construction and an 8 mm outside diameter give the cable a rugged feel suited to industrial and lab environments. Conductor resistance is specified at 51.2 Ohms per 1000 ft at 20 °C.

Installers needing shielded serial runs

Technicians who require a fully shielded DB9 extension with the option to rewire individual pins will find this cable a direct fit. Users looking for USB, Ethernet or fibre connectivity should look at other product types because this item is strictly a DB9 serial extender. Buyers who need a different connector gender or a right-angle hood will also need a different solution.

Simple plug-in installation with removable hoods

The cable plugs into existing DB9 ports without tools, and the metal hoods unscrew easily for repinning or inspection. The most common issue is forgetting to tighten the hood screws after repinning, which can weaken the EMI/RFI seal. Ensure each pin is fully seated before reassembly to avoid intermittent connections.
