Rectangular connectors, also known as headers, receptacles, and female sockets, are essential components used to pass data signals from one device to another. The 89891-403H is one such type of connector that is used in a variety of applications due to its high current rating and reliable electrical contacts. This article aims to provide an overview of the 89891-403H application field and working principle.

The 89891-403H is, as its name implies, a rectangular connector with a pitch of 2.54mm (0.1 inch). This makes it ideal for applications where space is limited and a standard connector may not fit. The 89891-403H is usually rated for a maximum current of 25A, and it features both male and female contacts that ensure the data signals are transmitted from one device to another without any loss or distortion.

The connector is available in both through-hole and surface-mount configurations, making it a versatile option for a variety of applications. Additionally, it is designed to withstand temperatures ranging from -55 to 105°C for long-term reliability. Additionally, it features a locking mechanism that ensures the connector remains secure even when subjected to high vibration levels.

The 89891-403H has a wide range of applications due to its versatility. It is commonly used in the industrial, automotive, military, and aerospace industries. It can be found in applications related to telecommunications, audio-visual equipment, power supplies, test and measurement equipment, as well as many other electronic devices.

In terms of working principle, the 89891-403H works by using two types of contacts: male and female. Male contacts are typically used to transmit data signals (i.e. supplying power, or providing a signal path for data transmission). Female contacts, on the other hand, are used to receive data signals from the male contacts. Both types of contacts are typically made of gold-plated copper for superior electrical conduction and durability.

When a data signal is sent from the male contact to the female contact, it passes through the connector\'s copper contacts, which then transfers the signal to the device it is connected to. This helps to reduce interference and signal distortion, while also ensuring the signal is transmitted quickly and efficiently.

In conclusion, the 89891-403H is a versatile, reliable, and high-performance connector that is useful for a variety of applications. Its flexible design, high current rating, and reliable electrical contacts make it ideal for applications that require data signals to be transferred from one device to another. Additionally, its locking mechanism ensures the connector remains secure even when subjected to high vibration levels. As such, the 89891-403H is a popular choice for many industrial, automotive, and aerospace applications.
