Black Box 50ft RS232 Metal Hood DB9 Male/Female Shielded Cable

Overview

The Black Box EDN12H-0050-MF is a 50-foot RS232 serial cable designed to connect devices using the classic nine-pin DB9 interface. It features a male connector on one end and a female connector on the other, making it ideal for linking computers to peripherals such as serial printers, barcode scanners, point-of-sale terminals, or industrial controllers. The cable’s 24 AWG tinned copper stranded conductors ensure reliable signal transmission over long distances without the need for repeaters.

Key features

• DB9 male and female connectors provide straightforward compatibility with legacy RS232 devices.
• 50-foot length offers ample reach for setups that require devices to be spaced across a room or workspace.
• Aluminum foil shielding reduces electromagnetic and radio-frequency interference, maintaining signal integrity in noisy environments.
• Removable metal hoods on connectors allow easy access for repinning or inspection without special tools.
• Stranded 24 AWG tinned copper conductors support consistent and durable signal flow.
• Compact 0.31-inch diameter cable fits easily into standard raceways and cable trays while remaining durable for daily use.
• All nine pins are wired straight through to ensure full RS232 compatibility with connected devices.

Connectivity and compatibility

This cable supports standard RS232 serial communication, making it compatible with a wide range of legacy and industrial equipment that use DB9 connectors. It works well in environments where devices need to be connected over longer distances without signal degradation, such as manufacturing floors, service benches, or retail checkout lanes.

Durability and ease of use

The cable’s sturdy PVC jacket and metal connector hoods provide protection against physical wear and electromagnetic interference. The removable hoods simplify maintenance tasks like repinning or wiring inspection, which is useful when adapting to changing project requirements. Its manageable diameter allows for neat routing through common cable management systems.

Ideal uses and environments

This RS232 cable is a strong choice for professionals maintaining legacy serial equipment, technicians running diagnostic tools, or businesses operating point-of-sale systems that rely on reliable serial connections. It fits well in industrial, retail, and workshop settings where interference and cable length are common challenges.
