Overview
The Black Box FA031 DB25 EMI/RFI metal hood is a protective connector cover engineered to block electromagnetic and radio frequency interference at the point where serial cables attach to equipment. EMI/RFI-resistant hoods stop damaging noise where cables are most vulnerable—at the connection. This standalone hood is manufactured by Black Box, a trusted name in industrial connectivity solutions, and provides an economical way to retrofit existing DB25 connectors with RF shielding without replacing entire cable assemblies.
Key Features
- Metal construction for effective EMI/RFI shielding
- Fits standard DB25 connector types
- EMI/RFI shielding blocks out noise and interference to keep data signals clear
- Ideal for industrial environments with high electrical noise
- Cost-effective retrofit solution for existing connectors
- Compact form factor for cable management
Technical Specifications
Based on Black Box’s EMI/RFI hood product line, the FA031 is designed to match standard DB25 connector geometry. Specific dimensional and material data should be verified with Black Box or your system integrator. Common uses include RS-232 serial connections and legacy industrial equipment communications where noise immunity is critical.
Typical Applications
- Manufacturing floor equipment with high EMI/RFI present
- Industrial automation and PLC serial communications
- Legacy RS-232 device protection in electrically noisy environments
- Data integrity in facilities with fluorescent lighting, radio transmitters, or heavy machinery
- Retrofit shielding for existing DB25 installations
Compatibility & Replacements
Compatible With
- DB25 male and female connectors (standard RS-232)
- Industrial serial communication equipment
- Legacy computer and PLC I/O systems
- Equipment with standard DB25 connector pinouts
Replaces / Drop-In Replacement For
The FA031 is a standalone hood component. Verify compatibility with your specific connector and equipment configuration before ordering. It does not replace complete cable assemblies, but rather adds shielding to existing DB25 connections.
Works With
- Black Box ED/Q series cables
- Standard DB25 industrial connectors
- RS-232 serial communication protocols
- Industrial automation networks and legacy control systems
