Black Box 20ft RS232 Serial Cable DB9 Male/Female Shielded PVC

The Black Box BC00232 is a 20-foot RS232 serial extension cable that gives you dependable reach between any two DB9 devices. It carries all nine signals straight through, so every hardware handshake and control line arrives intact. Technicians who service point of sale stations, industrial controllers, or legacy computer gear will find it especially useful when the original lead is just a little too short.

Inside the beige PVC jacket you will find 26 AWG stranded conductors that bend easily yet stand up to routine movement. A layer of Mylar shielding surrounds those wires to help block electromagnetic and radio-frequency interference that can appear in busy wiring closets, factory floors, or offices packed with electronics. Molded hoods add strain relief, and thumbscrews on both ends let you lock each connector firmly in place so accidental disconnection is far less likely.

Whether you are extending the cable on an AT-style mouse, linking a vintage EGA or CGA monitor, or tying a console port to a distant rack, this cable delivers clean, stable data with minimal fuss.
