499786-9

Rectangular connectors, also known as headers, male pins, and PCB terminals, are common types of electrical connectors found in a wide range of applications. The most popular type of rectangular connector is the 499786-9. It is designed for use in low-voltage applications such as circuit protection and control boards.

The 499786-9 is a standard rectangular connector that has two different contact configurations: four contacts and two contacts. The four-contact version is the most commonly used version, with four rows of two pins. Each row forms a closed circuit that when closed forms an electrical connection.

The two-contact version is rarely used and is a simplified version of the four-contact variation. It has two rows of two pins and forms an electrical connection with the first two pins. Typically, one of the two pins is used for voltage regulation and the other for a signal. In this way, two contacts are used to provide a secure electrical connection.

The 499786-9 is a robust and reliable connector. It is designed to withstand the rigors of extreme temperatures, vibration, and other environmental influences. It also comes with a broad range of mounting options, including through-hole, surface mount, and headers. It is also compliant with RoHS, UL, and CSA specifications, and is UL 94 V-2 rated.

The 499786-9 is a versatile connector. It can be used in a wide variety of applications, including computer peripherals, industrial automation, power, and control. It is especially popular for use in consumer electronics, such as cell phones, laptops, and tablets. It is also used in medical, automotive, telecommunications, and military applications.

The 499786-9 works by creating an electrical connection between two mating connectors. The two connectors are typically made of plastic and are attached to a mounting plate. The contacts on the connectors mate and form an electrical connection. Depending on the application, the connectors can also be soldered for a more secure connection.

The 499786-9 is easy to install and maintain. It requires no special tools, and it is easy to replace and clean. It is also highly reliable and offers excellent electrical and mechanical performance. In addition, it is a low-cost solution, making it a popular choice for many applications.

In summary, the 499786-9 is a reliable and versatile rectangular connector that is suitable for a wide range of applications. It is inexpensive, easy to install and maintain, and offers excellent electrical and mechanical performance. It is also compliant with UL, CSA, and RoHS standards, making it an ideal choice for many applications.
