Black Box EMN25C-0005-MF RS232 Double Shielded Extended Cable
Overview
The Black Box EMN25C-0005-MF is a double-shielded serial cable designed for robust RS-232 data transmission. Its construction minimizes electromagnetic interference (EMI) and radio frequency interference (RFI), ensuring signal integrity in electrically noisy environments. This cable is essential for maintaining reliable communication between serial devices like industrial controllers, POS systems, or legacy diagnostic equipment where data accuracy is critical.
Compatibility
This cable is designed for use with any device featuring a standard DB9 (9-pin) male serial port and requiring an RS-232 interface. It is suitable for connecting to industrial PCs, PLCs, network switches with serial consoles, and other equipment requiring serial data links. The extended length provides flexibility in device placement.
Installation Notes
Ensure that both connected devices are powered off before making or breaking connections to prevent potential data corruption or hardware damage. The double-shielded design offers enhanced protection against interference, making it suitable for deployment near power cables or in manufacturing floors.
