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

This DB9 male RS232 breakout module converts standard 9-pin D-SUB serial port into independent screw terminal block, eliminating complicated soldering operations for industrial serial wiring. Each pin corresponds to a separate screw terminal; users only need to strip wire insulation and lock copper conductors tightly to finish signal connection quickly.

Equipped with matching white plastic enclosure to shield circuits from dust, metal scraps and accidental short circuits in workshop environments. The PCB surface is printed with distinct serial pin numbers, which greatly simplifies wiring inspection and equipment debugging work.

The package contains 10 male DB9 breakout adapters for mass deployment of serial communication equipment such as PLC controllers, data acquisition modules, industrial sensors and serial debugging tools. Plug-and-wire design requires no welding, widely applied in factory automation wiring, laboratory signal testing and old serial hardware renovation.
