A solder-tail DB9 male connector for serial communication interfaces including RS-232, RS-422, and RS-485. This is one of the most widely used connectors for serial data links in industrial, embedded, and legacy computing applications.

Key Features

• DB9 Male (DE-9) – Standard 9-pin D-sub connector
• Solder-Tail Termination – Solder cup contacts for custom cable assembly
• Multi-Protocol – Compatible with RS-232, RS-422, and RS-485 serial interfaces

RS-232 Cable Length Guidelines

Maximum RS-232 cable length depends on baud rate, cable capacitance, and ambient noise. The following are general guidelines:

• 19 200 baud – Up to 15 m (50 ft)
• 9 600 baud – Up to 150 m (500 ft)
• 4 800 baud – Up to 300 m (1 000 ft)

Ideal For

• Custom RS-232/RS-422/RS-485 cable assemblies
• Industrial serial communication links
• Embedded systems and microcontroller UART connections
• Legacy equipment interfacing
