Rectangular Connectors - Headers, Male Pins, are components used for making electrical interconnections. As part of this category, the 3793-5203 Rectangular Connector is a versatile, popular part used in a wide variety of applications. This post reviews the applications and working principles of the 3793-5203.

Applications

The 3793-5203 is a 41-position rectilinear connector and is available in a variety of pin counts from 2 to 40 pins. It is mainly utilized in low-power applications such as in electronic instrumentation and consumer electronics. With its ability to be soldered directly to boards or mounted via two 6.35mm square posts, the 3793-5203 can be used as a basic interconnection system with low-level signals.The 3793-5203 is also widely adopted in the communications equipment, networking, and medical electronics industries with its stackable design allowing up to three connectors to snugly fit on a 19-pitch connector.Additionally, the connector is compatible with fingers, locks, and nuts for multiple uses. It also comes with two strokes of reliable gold-plated contacts which give it the extra protection of an additional 1.2-micron thickness of goldplate for any sensitive circuits.Thanks to its robustness and wide range of features, the 3793-5203 is the perfect connector for many commercial and military standard high-power applications, such as datacenters, data storage, servers, and computer networking equipment.

Working Principles

The standard 3793-5203 is designed to mate with a pin count of 2 to 40 and can be soldered directly to the board. It has reliable contacts with 2 strokes of gold-plated contacts. The body is made of corrosion-resistant, thermoplastic, UL94V-0. With its dual-beam terminals, it is easy to make a secure connection.The contact layout of the 3793-5203 has terminals on either side, allowing for the creation of symmetrical pairs of pins. This layout gives balanced pin currents, which eliminates the concern of power line radiation and minimizes crosstalk from neighbouring pins.The 3793-5203 is designed for high retention force, allowing it to withstand up to 5.5lbs of force per contact without damage. It also features a 5AMP current-carrying capability, allowing it to operate at up to 5.6AMP power rating.In order to ensure security and reliability, the 3793-5203 features a self-spring locking system. This provides the connector with the perfect balance to attach and detach from the mating surface without damage. Additionally, a keyed lance provides further protection against the assembly accidentally being unplugged. The connector is also roHS and REACH compliant, making it a safe and reliable solution for professional projects and applications.

In summary, the 3793-5203 Rectangular Connector is ideal for a variety of low-power applications. It is reliable, versatile, and designed to meet the demands of high-power applications. With its robust design, UL approval, high retention force, and dual-beam terminals, the 3793-5203 is the perfect connector for any commercial or military standard system.
