D-Sub, D-Shaped Connectors - Accessories are commonly used in a variety of industries, from automotive to telecoms to medical and more. In this article, we will focus on the application field and working principle of 748274-2.

What is 748274-2?

748274-2 is the style reference of a type of D-Sub connector. It is a 3-row, 2-shield, PCB D-Sub connector with a 1.27mm pitch. This means that it has a 3 pin-row layout, with 1 row of pin/socket contacts and two rows of shield GND contacts. The pins/sockets are arranged with a 1.27mm pitch along the cable, and the shields are arranged with a 2.54mm pitch.

Application Field and Working Principle of 748274-2

The 748274-2 is commonly used to provide connection and signal integration between different types of electronics and mechanical systems. It is used to create a physical connection between the external wiring system and the internal components of the device, thus allowing the internal components to communicate and exchange information with each other securely.

The 748274-2 has a contact force rated at 4 Newtons and a current rating of 4A, depending on the size of the connector. This type of connector is typically used in applications such as assembly machines, home automation, transportation systems, and so on.

The working principle of the 748274-2 is relatively simple. When two D-Sub connectors are mated, they form a physical connection between the pins. This connection allows electrical signals to be sent between the two connectors. Additionally, the connector contacts are protected from shock, vibration, and other physical insults that could potentially damage the device in the event of a disconnect.

Conclusion

The 748274-2 is a type of D-Sub, D-Shaped Connectors - Accessories, and is commonly used in a variety of industries. It is used to provide connection and signal integration between different types of electronics and mechanical systems, and has a contact force rated at 4 Newtons and a current rating of 4A. The working principle is relatively simple, with two mated connectors forming a physical connection between the pins.
