The 1-521385-3 is a type of rectangular connector, commonly referred to as a header. It has male pins and is used in various electrical applications. This article explores the application field and working principle of the 1-521385-3 connector.

The 1-521385-3 connectors are most typically found in the automotive sector, however they can be used in a variety of industries and are widely used in consumer electronics, communication systems, and medical equipment. The design of the connector makes it ideal for applications where space is limited, as the 1-521385-3 is only 38.1mm in total length. Additionally, the connector has a very deep insertion depth of 25mm and a high voltage rating up to 30V, making it a great choice for high-voltage applications.

The 1-521385-3 connector consists of a metal housing and two rows of gold-plated male pins, with the spacing of the male pins set at 5.9mm. The male pin can accept wires from 24-28 AWG. The back of the housing has two holes for mounting, along with two locking clips to ensure secure connection. Furthermore, the connector has a mated locking structure and seals on both sides of the board, providing a higher level of protection from dust and moisture. In order to ensure a reliable connection between the connector and the board, the connector must be soldered to the board via the holes in the back of the housing.

The typical working principle of the 1-521385-3 connector is simple and straightforward. Once the connector is mated with its receptor on the PCB, the male pins make contact with the traces on the board and an electrical connection is established. The locking clips and seals then ensure that the connection is held securely in place and is protected from the elements. The connector can then be used to carry power or signals to the desired components on the PCB.

In conclusion, the 1-521385-3 connector is a common choice for applications where space is limited. It is typically used in the automotive industry, but can be found in a variety of other industries. It has a metal housing and two rows of gold-plated male pins with a 5.9mm spacing. The mated locking structure and seals on both sides of the board provide additional protection against dust and moisture. The 1-521385-3 is a great choice for high-voltage applications, as it has a deep insertion depth and a high voltage rating up to 30V. Lastly, the working principle of the 1-521385-3 is simple and straightforward; the male pins make contact with the traces on the board and an electrical connection is established.
