Black Box 25ft RS232 DB9 Male/Female Shielded Cable

The Black Box EDN12H-0025-MF is a 25-foot RS232 serial cable that links DB9 male equipment to DB9 female equipment without compromise. Designed for places where legacy or specialized hardware still earns its keep, it provides a reliable way to reach printers, terminals, modems, or controllers while keeping interference at bay.

Inside the outer jacket you will find nine conductors rated at 24 AWG. Each conductor is stranded and made of tinned copper, then wired straight through from one end to the other so every pin on the host maps exactly to the same pin on the device. A shield formed from 100 percent aluminum foil wraps the core, blocking the electromagnetic and radio-frequency noise that often appears near power cables, motors, or wireless access points. This structure helps your serial traffic stay clear and stable, even across the full 25-foot run.

The cable is finished with robust metal hoods that can be removed for repinning when system layouts change. At 0.31 inch in outside diameter, the jacket balances flexibility with strength, so the cable tolerates regular moves, reroutes, and service calls.

System integrators, field technicians, and anyone managing industrial or point-of-sale gear will appreciate the extra length. Use it to relocate a receipt printer to a better countertop spot, extend a touch screen terminal on a kiosk, or pull a feed from a lab instrument that must stay inside a fume hood. Wherever RS232 remains part of the workflow, this cable provides a straightforward, low-noise connection.
