DE9 Wire Solder Male D-Type Connector
The DE9 Wire Solder Male D-Type Connector is a standard 9-pin connector widely used for serial communication and data transfer applications. It features a classic D-subminiature (D-sub) shape with two rows of pins (5+4 configuration), providing robust and secure connections for RS-232 interfaces, control systems, instrumentation, and legacy computer equipment. The solder-cup terminals allow easy and reliable cable assembly by hand soldering, making it a versatile choice for custom cables, repairs, and prototype setups. This male connector fits standard DE9 female ports and can be mounted in metal or plastic shells for extra durability and shielding. With its sturdy construction and dependable performance, it remains a staple in industrial, communication, and automation setups where stable serial connections are critical.
