Rectangular connectors are one of the most popular and widely used styles of connectors due to their compact size, reliable connections, and easy installation. They are widely used in a range of industries such as medical, telecommunications, automotive, industrial, and consumer electronics. The rectangular connector style we will be discussing here is known as the 1-1903131-3 housing-style connector.

This rectangular connector housing is a part of the AMP MATE-N-LOK series and comes with four contact cavities. Each cavity can take in two single-wire contacts enclosed within a metal alloy that provides greater durability and electrical insulation. The four-prong housings are available in high-temperature plastics such as nylon and polycarbonate, offering increased vibration and shock resistance to make them suited for industrial and automotive applications.

This particular housing is a dual-wall design that combines an outer shell and an inner insulating member for enhanced insulation against current leakage. The inner insulating body also comes with a two-piece snap-fit design that ensures secure engagement of the contacts while aiding in the efficient installation of the connector. Additionally, the intersecting slots on the back of the connector facilitate panel mount attachment for added security.

The 1-1903131-3 rectangular connector housing is designed to provide efficient electrical and mechanical connections between two circuits while allowing them to be disconnected conveniently. It is also designed to protect the contacts from damage due to severe environmental conditions. The primary working principle of the rectangular connector housing is to ensure reliability, accuracy, and durability in the electrical connections between two circuits.

This particular rectangular connector housing is UL listed and CSA approved, making it ideal for use in commercial and industrial applications. Additionally, it meets numerous international standards such as IEC 60512-7-211, IEC 60352-2-411, DIN EN 60352-2-411, RoHS, and REACH.

In conclusion, the 1-1903131-3 rectangular connector housing is an excellent choice for applications that require reliable electrical connections. Its compact size, easy installation process, and dual-wall design offer the necessary level of protection from environmental conditions, making it an ideal choice for a range of industries. Furthermore, its multiple international certifications and approvals ensure its quality and reliability.
