Rectangular Connectors—Headers, Male Pins, are widely used electronic connectors. Among them, 77311-120-03 is one of the most popular types. This article is intended to introduce the application fields and working principles of 77311-120-03.

77311-120-03 connectors are commonly used in electronic applications such as computers, telecommunication systems, data transmission networks, automotive electronics, consumer electronics, and industrial machinery. This connector includes a die-cast shell, which offers an IP67 water-resistance rating. Moreover, it is designed with an adjustable cable gland for flexible installation, making it a great choice for any environment.

The 77311-120-03 header features a specialized design, providing a secure connection between two devices. It features a very low profile design with a complete 360-degree shield connection and it allows mating both horizontally and vertically. It greatly simplifies mating and mounting design challenges. The 77311-120-03 header also has a unique mechanical keying system that avoids wrong connections. At the same time, the pins have a self-aligning design to ensure a perfect connection. All in all, the 77311-120-03 header provides excellent performance and reliable protection.

77311-120-03 working principle is relatively simple. It contains two parts, the male pin and header (the female part). The header part has grooves or holes which match the size and shape of the male pins. As a result, when the male pins are inserted into the female part, an electrical connection is established. The connection is maintained as the pins press against the conductive surface, providing a tight and secure connection.

In addition, the 77311-120-03 header has special insulation to prevent contamination between contacts. This feature is especially important for applications in which the connector is exposed to adverse environmental conditions. Furthermore, the 77311-120-03 header has a locking mechanism which ensures the electrical connection is secure and does not become loose. Thus the reliability of the connection can be guaranteed.

In conclusion, the 77311-120-03 header is an ideal connector for a variety of applications due to its excellent performance and reliable protection. The low profile design and adjustable cable gland make it suited for any environment. Moreover, the self-aligning design and locking mechanisms provide a strong electrical connection and excellent protection against contamination.
