Black Box 75ft Metal Hood RS232 DB9 Male/Male Shielded Cable

The Black Box EDN12H-0075-MM is a 75-foot RS232 cable with DB9 male connectors at both ends, built for situations where consistent serial communication matters. Its design centers on reliability, using a full metal hood and comprehensive shielding to keep electromagnetic noise from disrupting data while also protecting the connector housing from physical wear.

This cable excels when equipment must be positioned far apart yet still exchange data without errors. In a manufacturing plant, it can link a programmable logic controller to a monitoring station on the other side of the floor. In a retail environment, it can connect a point-of-sale terminal to back-room hardware without running into signal issues caused by nearby machinery or fluorescent lighting. IT teams also rely on it for console access to network switches or routers mounted several racks away.

The generous length reduces the need for extra couplers that might introduce points of failure. The male DB9 ends plug directly into standard serial ports, so setup remains straightforward whether you are working on test benches, laboratory instruments, or legacy servers that still depend on RS232 interfaces. Shielding maintains signal integrity over the full run, minimizing the troubleshooting headaches that come with intermittent data loss.

Because the cable balances durability with performance, it suits both industrial and commercial spaces where uptime is non-negotiable and where cables often face tougher treatment than in an office.

Highlights:

• Shielded construction limits electromagnetic interference and preserves signal clarity
• 75-foot (22.8-meter) reach supports long-distance device placement
• Metal hood adds mechanical strength and protects the connector housing
• DB9 male to male configuration fits standard RS232 ports without adapters
• Well suited to industrial automation, retail point-of-sale, laboratory, and network console applications
