10 Pack White DB9 Male RS232 Breakout Board with Housing, Solder-Free D-SUB 9Pin Serial Port to Terminal Block Wiring Adapter Module

This DB9 male breakout module comes with a complete white plastic housing, converting standard RS232 D-SUB 9Pin serial signals to easy-access screw terminal blocks. No soldering tools are required; users can directly fix stripped wires onto terminals via screws for rapid assembly. Every pin position is clearly printed on the PCB surface to prevent wrong wiring during PLC communication, equipment debugging and data acquisition work. Pre-set mounting holes allow stable fixation on chassis, test benches and industrial control panels to avoid loose connections caused by cable pulling. Made of sturdy insulating PCB and anti-oxidation gold-plated DB9 pins, the adapter delivers stable serial signal transmission with strong anti-interference performance, supporting long-term continuous operation of industrial automation equipment.

Sold in a pack of 10 white male breakout boards, ideal for batch maintenance, laboratory testing, machine tool signal wiring and DIY serial communication projects. Plug-and-wire design greatly improves wiring efficiency for technicians and system integrators.
