Rectangular connectors, also known as headers, male pins or D-subminiature connectors, are electrical connectors that generally consist of two or more parallel rows of pins or sockets surrounded by a D-shaped metal shield that provides mechanical support, ensures correct orientation, and screen against electromagnetic interference (EMI). 4-102972-0 rectangular connectors are a common type of rectangular connectors used in many electronic applications.

Application fields for 4-102972-0 rectangular connectors include electronic instrumentation, telecommunications, test and measurement equipment, computer networking, medical equipment, industrial controls, military equipment and avionics, automotive electronics, and more.

Measuring approximately 0.18” wide and 0.250” high, the versatile 4-102972-0 rectangular connector features four signal contacts and two grounding pins on both sides of the connector. The contacts are arranged in groups of three, referred to as triple-stacking, which allows for higher integration density than the traditional double-stacking arrangement in terminals with 10 or fewer pins. The design also allows for 360-degree ground clip retention, increasing mechanical robustness for high vibration environments, and performance in high power applications. Permanently attached shields offer additional protection for the internal pins and sockets and provide EMI shielding.

4-102972-0 rectangular connectors use a mechanical interlocking system that eliminates the need for soldering and ensures a reliable connection in high-temperature and shock/vibration applications. The connectors are also highly reliable in wet environments due to a water-tight and dust-tight seal.

In addition to a wide range of standard rectangular connectors, 4-102972-0 connectors are also available with different pin configurations and contact materials. The most common materials for the contacts are stainless steel and plated copper alloy, and there are also variants with gold-plated tips and tails for high speed applications.

To ensure reliable connections, user installations typically include an amount of force applied to the connector when mating. This results in a very effective and secure connection with robust mechanical strength and low contact resistance, but the force required to properly mate the connectors must also be taken into account when selecting the correct type of connector.

The working principle of the 4-102972-0 rectangular connector is simple and straightforward. The contacts are permanently held in place while a spring-loaded mechanism is used to ensure contact tension. To mate the connector, the spring-loaded mechanism is actuated in one of two ways: either by the user manually pushing the connector into place, or by a mechanical interlock. When the respective construction are properly mated, the contact is secured and held in place.

The 4-102972-0 rectangular connectors are a popular choice for applications requiring reliable mechanical strength, contact tension, and electrical conductivity. Their unique design and excellent electrical and mechanical characteristics allow for easy and reliable user installations, making them ideal for a wide range of electronic device applications.
