These four DB9 female breakout connectors convert a standard RS232 DSUB DB9 interface into nine individual connections. The breakout is solderless, allowing quick, tool wiring without any soldering. Each unit provides a DB9 female interface on one end and a 9pin terminal breakout on the other, enabling easy access to RS232 signals for prototyping, testing, and panel wiring. Key benefits Quick, solderless wiring: no soldering required, save time on setup and rework. Direct access to RS232 signals: 9 individual terminals map to the DB9 pins for clear, organized wiring. Easy integration: compact, lightweight design suitable for enclosures, test rigs, control panels, and desk setups. Versatile use: ideal for prototyping, diagnostics, field service, and lab work. Key attributes Includes 4 pieces DB9 Female breakout connector Solderless RS232 DSUB serial to 9pin port terminal adapter connector Breaks out all 9 DB9 signal pins to separate terminals Compatible with standard RS232 devices and DB9 cables Applications and use cases Prototyping and development: connect a PC or RS232 device to a microcontroller or embedded system by routing signals through individual terminals for easy testing and debugging. Diagnostics and testing: attach test leads to specific RS232 lines for troubleshooting, signal monitoring, or equipment validation without soldering. Panel wiring and replacement: streamline wiring in control panels or legacy equipment by substituting a DB9 breakout with readytouse terminals for reliable connections.
