The A4B-11PA-2DS(71) header pin is one of the most versatile rectangular connectors widely used in the world. Developed by Tyco Electronics, these headers come in various layouts and have been part of the industry standard for more than two decades. They are generally used in applications that require quick disconnection/reconnection of cables, wires, and other electrical components in which power or signal transfer takes place. The A4B-11PA-2DS(71) header pin is designed for use in a wide range of industries and applications, including medical, security, telecom, and consumer electronics.

The A4B-11PA-2DS(71) header pin is a rectangular-shaped, multi-contact connector consisting of two main parts: the socket, which contains the contacts for mating, and the header, which provides mechanical protection to the contacts. The inner portion of this connector contains four rows of circular-shaped contacts with plastic retention lugs that can be mated with metric or imperial-sized wires and cables. It is widely used for power and signal routing in various applications, such as advanced robotic systems, wireless communication devices, and machine control systems.

The A4B-11PA-2DS(71) header pin features two distinct contact elements: the male pin and the female socket. The male pin is the portion of the header that is inserted into the female socket. It is available in a variety of sizes ranging from 0.050" to 0.125" (1.27 mm to 3.18 mm). The contact tip is usually made of brass and is tin-plated for enhanced corrosion resistance. The contacts are often gold-plated to protect against oxidation, a common problem in electronic connectors. The female socket is also a key component of the header. It is designed to accept the male pin which is inserted into it. The socket is typically constructed from UL94V-0 rated thermoplastic and has a standard retention force, which ensures that the mated contacts are held securely in place.

The A4B-11PA-2DS(71) header pin has a wide range of applications and can be found in a variety of industries. It is used for the electrical connections of multiple systems such as medical devices, commercial vehicles, industrial robots, and consumer electronics products. This header is mostly used in robotics and control systems for quick power and signal connection. It is also utilized in automotive and military applications due to its excellent signal stability, vibration resistance, and mechanical protection. Moreover, it is also used in telecom and telecommunications for the transfer of data and power.

The working principle behind the A4B-11PA-2DS(71) header pin is simple. When the user inserts the male pin into the female socket, the contacts on the pins make secure contact with the contacts on the socket. The tension of the contacts is then maintained, allowing an electrical connection between the two connectors. When the user needs to disconnect the pins, the retention lugs hold the pins securely until they are manually removed.

In conclusion, the A4B-11PA-2DS(71) header pin is one of the most popular rectangular connectors widely used in the world. It offers a reliable power and signal connection with superior electrical and mechanical protection. It can be used in a variety of applications and is especially useful for robotic and control systems. It has two distinct contact elements - the male pin and the female socket - and its working principle is simple and straightforward.
