D-Sub Connectors are the most common type of connection used in electronics today due to their long-standing popularity and wide range of applications. The 2221860-1 is a specific type of D-Sub connector that plays an important role in applications such as telecommunications, computers, medical and automotive. It is also suitable for connecting networks, instruments, controllers and computers.

Application Field

The 2221860-1 is a 9-pin male version of the D-Sub connector, commonly used in RS-232 (Recommended Standard 232) systems that allow serial data transmission. More specifically, the 2221860-1 D-Sub connector is used for RS-232C serial interface and can connect to most types of equipment including modems and printers. It is suitable for use in high-density connections since it offers a smaller size and is relatively easy to use. It is also designed with a Terminal Position Assurance (TPA) system that ensures its pins fit together securely.

The 2221860-1 D-Sub connector is a popular choice for many applications such as ATMs, point of sales, medical imaging equipment, kiosks, among others. It can also be used in audio and video equipment like mixers, camera links, or as the primary connection point in electronic networks.

Working Principle

The 2221860-1 D-Sub connector is typically a 9-pin male connector with gold plated contacts and Teflon insulation that can provide excellent shielding performance against EMI (electromagnetic interference). This shielding is mainly achieved through a rotating hood that covers the back of the connector and screws directly into the main body. This ensures that the contacts remain protected from physical damage while also providing effective protection from EMI.

The 2221860-1 D-Sub connector is designed with metal spring clips that hold the wires firmly in place when the hood is properly tightened. This creates a vibration-proof connection between the two components that ensures smooth data transmission. Furthermore, the Teflon insulation increases the connector’s resistance to heat, providing reliable performance even in extreme environments.

Overall, the 2221860-1 D-Sub connector is ideal for many different applications where data must be transferred accurately and reliably. Its robust design and excellent shielding performance ensure that the connection remains secure and the data remains protected from interference.
