Rectangular Connectors - Headers, Male Pins are widely used in various aspects, of which the 1-1871673-3 is an exemplary product. This article aims to discuss the application field and working principle of the 1-1871673-3.

The 1-1871673-3 rectangular connector is a single-sinker version of a standard PCB header. It has a 4.2 by 2.54 mm pin spacing, with three dimples for alignment between the pins. Its contact insertion force is 4N max, while the normal force of the contact is 0.5N max. Overall, this design creates a secure connection that is both mechanically and electrically reliable, which are essential features of any good PCB header.

The 1-1871673-3 male pin is often used in a wide range of applications, such as in the fields of communication networks, communication modules, military and aerospace, sensing devices, medical and automotive. Thanks to its features of secure connection, high-speed data transmission, strong reliability, great wear resistance, and etc., it can also be applied in the custom electronics projects.

Now let’s explore its working principle. In general, the 1-1871673-3 header works by receiving power or data from the main circuitry board, and then transferring the signal to whichever devices it is connected to. This is done by sending the signal through the pins in the header, to which the target device is then wired. The connection between the header and the target device is established using a suitable wire/ cable whose other end is connected to the target device.

The 1-1871673-3 connector has a single-pole configuration that ensures reliable high-speed signals are transferred to the target device. It also features a solder tail that has two portions, bottom and top, that allows for easy connection with the main circuitry board. The header is also designed to ensure a good electrical contact between the pins and the target device. This is done by ensuring that the pins are properly aligned with the target device, as well as providing easy adjustment of the connection force to ensure a suitable contact force.

To conclude, it can be said that the 1-1871673-3 rectangular connector is a popular product in many fields, such as in communication networks, communication modules, military and aerospace, sensing devices, medical and automotive. Its working principle is based on connecting power or data to target devices, and is characterized by high-speed data transmission, strong reliability, and great wear resistance.
