D-Sub connectors, which are also known as D-shaped connectors, are used in a wide variety of applications such as computers, automotive, and telecommunications. There are several types of D-Sub connectors with different configurations and sizes to suit the requirements of each application. The 1218234-5 D-Sub connector housing is a 9-pin configuration that provides shielded protection to help reduce interference in the signal path. The 1218234-5 is a larger type D-Sub housing which is used in the industrial field for applications such as automotive, communications, and medical.

The 1218234-5 D-Sub connector is a double row connector with nine-pin connections. It is composed of two parts, a molded plastic body which encloses the electrical contacts, and a die cast shell which provides an EMI/RFI shielding for the contacts. The plastic body has an effective shielding of 50 dB and the die-cast shell has an effective shielding of 90 dB. The die-cast shell also provides a mounting base for the connector, while the plastic body serves as the main contact point. The die-cast shell is a three-piece design and is connected with screws to the mounting base.

The electrical contact of the 1218234-5 is composed of four terminal pin sockets, four solder pins, and one ground pin. The terminal pin sockets provide a secure and reliable connection between the mating contacts and are constructed with plated brass terminals. The solder pins are made of plated steel and are used for mounting the terminals onto the printed circuit board. The ground pin is used to provide a ground connection between the outside case of the connector and the mounted circuit board.

The 1218234-5 connector housing has excellent environmental characteristics which make it suitable for operation in harsh conditions. The connector is resistant to vibration, corrosion, temperature, and humidity. It is UL listed and rated to a current rating of 5A. This is a very important feature, as it allows the application to be used in a variety of harsh environments.

The working principle of the 1218234-5 D-Sub connector is relatively simple. The two pieces of plastic housing are connected together using screws and the contacts within the housing are sealed to prevent dust and moisture ingression. Once the connector is inserted into the mounting hole on the PCB, the copper conductor is then wired to the contact, completing the circuit. When the contacts are mated, the electrical signals are transferred from one contact to the other, allowing for reliable and error-free transmission of information.

The 1218234-5 D-Sub connector is well suited for applications that require a reliable and secure connection such as automotive, medical devices, and communication systems. Its rugged construction and superior shielding provides excellent EMI protection and provides high reliability in harsh environments. Additionally, the 1218234-5’s versatility, with its various configurations and sizes, makes it a great choice for a wide variety of applications.
