Rectangular Connectors – Headers, Male Pins

Rectangular connectors, also known as headers, are an important component in many different types of electronics. These connectors have exposed contacts called male pins that increase the reliability of an electrical circuit. The 4-102978-0-04 is commonly used in a variety of applications where a reliable connection is required.The 4-102978-0-04 has two rows of four pins and is designed to provide a sturdy connection between components. There are several advantages of using this type of connector in comparison to other types. The main advantage is reliability. Headers are designed to ensure that a secure connection is maintained, regardless of the environmental conditions. This greatly reduces the risk of electrical faults occurring in the circuit.Another advantage is that they are easy to use. They are easy to mount and require minimal installation time. The headers are also designed to be extremely robust, meaning that they can withstand a wide range of temperatures and humidity levels. This means that they can be used in a variety of environments.The working principle of a 4-102978-0-04 is fairly simple. The male pins are designed to make contact with the corresponding female connectors. When a voltage is applied to the pins, an electrical connection is made. When the voltage is removed, the connection is broken. This process can be repeated over and over, providing a reliable connection.The 4-102978-0-04 is often used in applications such as telecommunications, computers, consumer electronics, and automotive applications. In the automotive industry, the headers are used to provide a secure connection for application such as airbag deployment systems, door locks, and engine systems. They are also used in medical equipment, where their reliability and durability make them ideal for connecting patient monitoring devices.In summary, the 4-102978-0-04 is a reliable and robust rectangular connector, which is suitable for a wide range of applications. Its ease of use, secure connection, and wide range of temperature and humidity tolerances make it a popular choice in the electronics industry.
