D-Sub DB9 Female Connector, PCB Mount, Through Hole, 2.77mm Pitch, 4-40 UNC Screwlock
Introduction:
This D-sub DB9 female connector is engineered for secure PCB mounting. It features integrated 4-40 UNC screw locks, ensuring a vibration-proof mating connection. The connector mounts using through-hole technology; its solder pins are inserted into the PCB and soldered to form a robust, permanent mechanical and electrical bond. This connector features nickel-plated contacts, providing an economical solution for reliable data connections. The wide operating temperature range and UL94 V-0 flame rating ensure reliability in demanding environments. A durable steel shell provides robust physical protection, making it an excellent choice for adding a standard female serial port to electronic devices and control panels.
This D-sub DB9 female connector has many great features, including:
- PCB Mount: Provides a strong mechanical anchor when soldered directly to the circuit board.
- Solder Termination: Forms a permanent electrical bond between the connector and the PCB.
- 4-40 UNC Screw Lock: Locks the mating connector in place, preventing disconnections from vibration or pull.
- Nickel-Plated Contacts: An economical choice that provides good conductivity for standard-duty use.
- Durable Steel Shell: Offers robust physical protection for the connection point.
