Rectangular Connectors - Headers, Receptacles, Female Sockets

Rectangular connectors aim to provide a secure electrical connection between two devices. These connectors come in the form of headers, receptacles, plugs and female sockets, which are equipped with a variety of styles and sizes to best suit their application. 89891-421H Rectangular Connectors are part of the 89891 Series of audio/video connectors, and are commonly used in a multitude of applications.

The 89891-421H Rectangular connectors are composed of die cast zinc alloy for high durability and performance. This particular series of connectors is composed of three parts including the header, receptacle, and female socket. The header is a multi pointed contact that exerts its force onto the receptacle at multiple points, securely connecting the two devices in question. Similarly, the receptacle end bears the contact forces to provide an electrical connection. The 89891-421H connectors have a total of four contacts and operate on 4-Pole/3-Tab Connector Standard.

The 89891-421H Series of connectors are typically used in audio/video applications as they are know to provide millions of mating cycles and support 1080-P resolution. The wide range of applications of 89891-421H connectors include home theater systems, CCTV, audio/video interswitch cables, laptops, televisions, and other media playback devices. Additionally, the connectors also provide strain relief between the electrical cord and the connector for secure connections and easy handling.

The 89891-421H connectors are designed with galvanized steel metal shells to provide shielding Protection from electromagnetic interference (EMI). The Rating is UL94V-2 compliant and the pins are Gold plated for efficient transmission of signals. The solder tabs of the 89891-421H connectors ensure that the connections are reliable and do not disconnect easily.

When it comes to proper installation, one must ensure that the male/female ports of the connector are correctly and securely aligned before tightening the screws of the connector to avoid problems with the alignment. It is also important to adhere to safety and caution rules while working with electronic equipment, ensuring that the user is wearing rubber gloves or does not touch any wire directly.

Due to their increased frequency of use, 89891-421H connectors are considered to be an economical and reliable alternative to the breadboard connectors, which are comparatively a more expensive option and require more effort for installation. The 89891-421H Connectors have become common equipment for home applications, and are used to ensure that the connections between two systems in an audio/video signal transfer are secure and remain in their places.
