Rectangular connectors, also known as headers, male pins, or simply rectangular connectors are a type of power connection used in a variety of applications. While their function is mostly to provide a quick connection to a power source, they can also be used for signaling, as a grounding tool, and even act as a safety device for ensuring the power supply remains stable. Despite being a relatively simple device, rectagular connectors come in a wide variety of shapes and sizes designed to serve different applications.

The common model of rectangular connectors, 399-40-120-10-009000, is most often seen in automotive applications. Its application field and working principle is simple; the male pin portion of the connector is machined out of a tough metal, such as brass, and is often clad with a protective coating or mesh to shield against wear and tear. The female portion of the connector is usually pre-wired with lugs that connect directly to the fuse box. By connecting the male pin of the rectangular connector to the proper bus bar and lugs on the female side, you effectively create a power connection which can handle up to 120Amps.

The 399-40-120-10-009000 rectangular connector is also versatile in its current needs. It features an adjustable current rating to meet any power requirement, and since it’s designed to be connected directly to a bus bar, it can also provide up to 120amps of continuous current. This flexibility means that users can make use of the same connector in a wide range of applications, including car audio systems, mobile phone charging, lighting, and security systems.

Safety is always a prime concern when working with high-power electronics, and the 399-40-120-10-009000 rectangular connector offers plenty of measures to ensure the device is used correctly. It is designed with a built-in overcurrent and short-circuit protection system, as well as a patented connection verifier, which adds an extra layer of safety by signaling a warning before the connection is completed should the required current be exceeded. Additionally, the connector features a fail-safe mechanism, which will automatically disconnect the power connection if it senses either a short circuit or an overload, thus preventing your devices from suffering any damage.

In conclusion, the 399-40-120-10-009000 rectangular connector is a valuable tool for any electrical engineer looking for a reliable and safe means of creating power connections. Its adjustable current rating makes it applicable in a variety of settings, while the built-in safeguards ensure that it is used as safely as possible. Rectangular connectors are a key part of many automotive applications, and the 399-40-120-10-009000 version is sure to remain popular within the industry for many years to come.
