Rectangular Connectors - Headers, Male Pins

The 641972-3 is a basically rectangular connector with headers on the male end and pins on the female end. It has a two-piece construction, with the male pin headers being the primary part of the connector system and the female pins creating the link between the two. The two piece construction allows for a much easier assembly process than many other types of connector systems, while giving the necessary strength and insulation from high voltage and humidity.

Application Field

The 641972-3 is designed for applications where high speed and reliability is essential. It is commonly used in high voltage switching systems, also known as power switching, for the connection of electrical circuits. It can be used for switching connections, such as in power distribution systems, motor controls, and control valves. Additionally, it is often used in communication equipment as well, such as telephone and modem systems, where it helps provide stable and secure connections.

Working Principle

The 641972-3 works on the simple principle of electrical contact between two surfaces. The pins on the female side of the connector system fit into the corresponding headers on the male side, while the male pin headers are connected by an insulation sleeve. When the male pin headers and female pins make contact, the current can flow through them safely and the insulation sleeve helps protect against any unwanted high voltage or current leakage. The connectors are designed with a very tight tolerance so the connection is secure with minimal movement and vibration. This helps to ensure high signal integrity and reliability, even in the most demanding applications. Additionally, the two-piece construction of this type of connector system makes it easier to assemble and connect than certain other types of connectors.

Other Features

The 641972-3 also features a low profile design that helps promote space savings, as well as integrated strain relief that keeps the connector system secure and prevents any movement, wear, or misalignment of the pins and headers.This connector system can also be used with a variety of additional components and accessories, including crimp or solder terminals, extended head pins, and secondary locks, among others. This allows the user to customize their connector system and create the exact combination and design that meets their needs.
