Introduction

89891-412H connector is a type of rectangular connector, which falls under the category of headers, receptacles, female sockets. Its main purpose is to provide a secure connection between an electronic device to a printed circuit board (PCB). This connector is extensively used in many applications, such as computer, medical, automotive, and consumer products.

Structure and Features

The 89891-412H connector is an 8-pin female connector featuring two rows of four pins. It is a two-piece design, consisting of the receptacle, which is soldered onto the PCB, and the header, which is then plugged into the receptacle. The receptacle has two sets of contacts on each side, which gives it a total of 8 pins. The header also has two sets of contacts on each side, with a total of 8 pins.The 89891-412H connector is a high-density connector. This means that it is small in size and can pack more pins into the same amount of space. This connector also has two polarization keys on the side, which prevents the connector from being plugged in at the wrong angle.

Application Fields

The 89891-412H connector is a versatile connector that can be used in a variety of applications, including computers, medical equipment, automotive, and consumer products. It can be used to connect a wide range of components, such as switches, LEDs, transistors, and other small components. In addition, this connector is capable of handling high current and voltage ratings, making it suitable for high power applications.

Working Principle

The working principle of the 89891-412H connector is simple and straightforward. It works by providing a secure electrical connection between two components. When the header is plugged into the receptacle, the contacts on each side align and create a secure connection. The polarization keys ensure that the connector can only be plugged in the correct orientation, and when the connection is secure, the header can no longer be removed.

Conclusion

Overall, the 89891-412H is a reliable and versatile rectangular connector that is used in a wide variety of applications. It is a high-density connector that is able to handle high currents and voltage ratings, allowing it to be used in high power applications. Additionally, it comes with two polarization keys on the side to ensure that the connector is inserted in the correct orientation. The 89891-412H connector is a versatile and reliable choice for many different applications.
