DB9 Male RS232 Breakout Board with Solder-Free Terminals & Protective Housing, D-SUB Serial Port Terminal Adapter

This DB9 male breakout module converts 9-pin RS232 serial signals into independent screw terminal leads, greatly simplifying serial circuit testing, wiring modification and fault diagnosis work. The solder-free screw terminal structure allows users to attach, adjust and replace wires conveniently without soldering operations.

Equipped with an integrated protective plastic housing, it fully covers exposed metal terminals to avoid short-circuit failures caused by debris or collision in equipment cabinets. Every terminal is printed with corresponding DB9 pin numbers, eliminating the trouble of repeated pin measurement during maintenance.

It supports standard RS232 serial communication signals, perfectly matching industrial control PLCs, frequency converters, access control systems and laboratory serial test instruments. Compact overall size saves installation space inside control boxes and test benches, serving as an essential auxiliary wiring accessory for automation and IT maintenance work.
