D-Sub 9Pin Connector FeMale (DB9) Solder Type
The D-Sub 9-Pin Female Connector (DB9 Solder Type) is a classic, robust connector used extensively for RS-232 serial communications, control signals, and legacy data interfaces. Featuring a compact 9-pin (5+4) configuration, it provides reliable and secure connections for computers, industrial equipment, and communication devices. The solder-cup terminals allow straightforward wire termination by manual soldering, making it ideal for custom cable assembly, repairs, and prototype development.
This female connector mates perfectly with standard DE9 (DB9) male plugs, ensuring compatibility across various serial devices and PC interfaces. Built with durable metal housing and optional strain relief hardware, it guarantees a stable connection with excellent shielding against EMI/RFI. The DB9 female connector is an essential component for technicians, hobbyists, and industrial integrators working with serial communication.
