D-Sub connectors are a type of electrical connector commonly used to connect computers and other electrical equipment. DE9SA190 is a standard nine-pin, dual-row, female-type D-Sub connector from DE series produced by Hirose. It is widely used in applications such as computer peripherals, data communication equipment, office automation products, and various other electronic components.

DE9SA190 is suitable for OIRF and OIRM sheild design, with the contact resistance value of 60mohm maximum at 1.6Amps, AC/DC voltage of 200V, and insulation resistance of 1000Mohm at 500VDC. Other features include RoHS and UL approvals, and complete insertion depth of 4.7mm.

The DE9SA190 is often used in automotive infotainment, navigation, communication, and medical/biometric systems, thanks to its reliability and high data transmission rates. The connector is designed for enhanced customer satisfaction, with improved product lifetime and increase in current capacity.

DE9SA190 D-Sub connectors can be used in a variety of applications. These include connecting multiple electrical components together in a single circuit, such as connecting a printer\'s data cable to a PC, connecting a microcontroller board to an LCD, and connecting an amplifier to speakers. It can also be used to connect multiple control systems to one another, such as in a car\'s engine management system, and is commonly used in audio/video equipment.

The working principle of DE9SA190 connectors is based on the fitting of metal pins or contacts into sockets or pins. The pins are inserted into the sockets of the D-Sub connector and the connection is secured with a metal screw or latch. The D-Sub connector has two rows of pins with a total of nine pins, five pins on one row and four on the other, and the screw or latch secures both rows together.

In use, the pins are inserted into the sockets of the connector and the connection is secured by tightening the screws. The pins are then connected to the corresponding wires, and the circuit is complete. The connection is then checked for consistency with a voltage tester, and if all pins are connected correctly, the system is ready to use.

In conclusion, DE9SA190 D-Sub connectors are a reliable and versatile type of electrical connector which are used in a variety of applications in both consumer and industrial settings. They are easy to install and secure, and offer fast data transmission. They provide a strong connection and are able to handle large currents, making them suitable for powering a wide variety of devices and systems.
