Rectangular connectors are an essential component in modern electrical and electronic designs. Commonly known as header connectors, they form an essential connection between PCBs and peripheral components, allowing users to create a secure and reliable physical interface.The A2-19PA-2.54DS(71) is a male pin on a two-row header connector and a key component for end applications. It features a 0.10 inch pitch, 19 number of contacts, 2.54mm outer diameter and a rated current of 1.0A.Understanding how a rectangular connector works is the basis for choosing the right connector for any application. The working principle behind header connectors can be understood in two steps.First, an electrical connector must be connected with a mating surface. Headers generally use an area contact system, which interlocks each contact within the connector. This contact system is designed to ensure a physical connection between the two mating surfaces of the connector, as well as an electrical one.The second step of the working principle is the locking of the headers into the mating surface. This is achieved by the use of specialized latching systems, which often consist of a tiered system of latches and contacts.The tiered latches ensure a secure physical connection between the connectors, while the contacts provide a stable electrical link between the two parts. For added security, many connectors also include an integral locking mechanism, such as a threaded fastener, which helps to extend the life of the electrical connection.The A2-19PA-2.54DS(71) header connector provides an excellent solution for a range of electronics applications, including telecommunications, aerospace, medical, and industrial applications. Its low profile design ensures that it can be installed in most applications without having to worry about space constraints.The A2-19PA-2.54DS(71) is made from a high-grade polycarbonate material, featuring a long service life and a good level of durability. In addition, the connector is rated for a high current capacity of 1A; making it suitable for a wide range of applications, from high-integrity power sources to low-end power applications.Moreover, the header connector offers excellent electrical insulation, with a signal loss of just 5dB/km with a standing wave ratio of 1.1. This ensures that the connector provides a high level of signal integrity, which is critical in many applications.The A2-19PA-2.54DS(71) is an excellent choice for a range of electrical and electronic applications. With its low profile design, high current capacity and excellent electrical insulation, the header can provide a secure and reliable connection between two electronic components. As a result, the connector is an ideal solution for a range of applications, from low-end industrial applications to high-end power sources.
