10 Pack White DB9 Female RS232 Breakout Board Solder-Free Terminal Block Adapter With Plastic Housing D-SUB Serial Wiring Module

This DB9 female RS232 breakout module converts standard 9-pin D-SUB female serial port into independent screw terminal blocks, removing complex soldering steps for industrial serial wiring. Each pin corresponds to an individual screw terminal; users only strip wire insulation and fasten copper conductors to complete signal connections rapidly. Comes with matched white plastic housing to guard internal circuits against dust, metal scraps and accidental short circuits in factory environments. Distinct serial pin numbers printed on the circuit board greatly simplify wiring inspection and equipment debugging work. The package contains 10 female DB9 breakout adapters, suitable for large-scale deployment of serial communication hardware including PLC controllers, data acquisition units, industrial sensors and serial debugging tools.

The plug-and-wire design requires no welding, widely applied in factory automation wiring, laboratory signal testing and renovation of legacy serial devices.
