Description
This DB9 male connector is a reliable serial interface component featuring a standard solder tail design. It is ideal for students, hobbyists, and makers building or repairing custom cables for RS232, RS422, and RS485 communication systems.
Universal serial protocol support
The connector is widely used across standard serial interfaces including RS232, RS422, and RS485. This makes it a versatile choice for DIY communication leads, microcontroller debugging, and legacy hardware interfacing.
Solder tail pinout design
Constructed with durable solder tails, this male connector allows for clean and secure wire termination. Refer to the standard DB9 pinout diagram when wiring power, ground, and serial data lines.
RS-232 cable length guidelines
The rated maximum cable length for RS-232 is 50ft, though practical distance varies based on baud rate, cable capacitance, and ambient noise. Based on Texas Instruments testing, lower baud rates allow longer runs, reaching up to 500ft at 9600 baud and 1000ft at 4800 baud.
Included in the package
The package includes one DB9 male connector ready for soldering into your custom wiring harness or interface board.
