Rectangular connectors are an important element in a majority of the electronic devices we use today. From cell phones to laptop computers, these connectors play an essential role in enabling communication between components. The 77311-401-03LF header is a type of rectangular connector, most often used as a board-to-board connection in a variety of applications. This article will discuss the 77311-401-03LF’s application field and working principle.

The 77311-401-03LF is a two-piece header connector made up of a black-plated silver-tin male terminal and a black-plated female socket. It is rated for up to 5.5A current at 90°C and 50.7 VDC. Due to its reliable performance and wide operating temperature range from -55°C to +125°C, it has become the standard for many high-performance applications and has been used in a variety of industries. It is a great connector choice for networking, automotive, industrial control, communications, medical and data storage applications.

In terms of its working principle, the 77311-401-03LF header connector is designed to provide secure connections between two board-level components. The male terminal is made up of two metal contacts that, when inserted into a socket, are held tightly together through the physical force of the socket pins. This ensures a secure connection to the other board-level component, without the need for soldering. Additionally, due to its RAST-5 anti-vibration system, the connector provides a resistant and reliable connection, even during the harshest environments and operating conditions.

Aside from its use in the above-mentioned applications, the 77311-401-03LF header connector also finds its use in the field of robotics. For instance, it is widely used in the construction of robotics arms, since the connector’s design ensures seamless, reliable communication between the servos and the robotic arm’s electrical components. The 77311-401-03LF header is also a great choice in environments wherein the connector’s gold plated contact pads have to be protected against corrosion or oxidation.

In conclusion, the 77311-401-03LF header connector is a reliable and versatile choice for a variety of applications. Its two-piece design allows for a secure connection without the need for soldering, and its RAST-5 anti-vibration system provides a reliable connection in harsh environments. Additionally, thanks to its gold plated contact pads, it is a great choice for applications wherein protection against oxidation or corrosion is a must. Despite being used primarily as a board-to-board connection, it also finds its use in robotics construction due to its design and durability.
