Backplane connectors - housings are widely used in a variety of industries including telecommunications, aerospace, consumer electronics, automotive, and medical. The 516-090-000-221 is a specific type of housing that is designed to meet specific application requirements in these industries. This article will discuss the application field and working principle of the 516-090-000-221.

The 516-090-000-221 backplane connector housing is a two-part system with a carrier board and a connector body. The carrier board is a PCB that is typically mounted on a frame with the connector body arranged into the specified configuration. The connector body consists of a pair of polarization keys, a set of contacts, and a metal enclosure. The polarization keys and contacts are placed in recesses in the metal enclosure and a mechanical lock is used to secure the two parts together. The metal enclosure also helps to protect the contacts and prevents any debris from entering the connector.

The 516-090-000-221 housing is designed for high-speed, high-current, and high-density applications. The connectors have a high current rating of 4.5 Amps, making them suitable for high power applications, and the contacts have a minimum pitch of 0.5 mm, making them suitable for very dense circuit boards. Additionally, the connector body contacts are plated with gold for improved corrosion resistance and high contact life. The design of the contacts also allows for high durability and reliable electrical connection.

The working principle of the 516-090-000-221 is relatively simple. The two parts of the connector are mated together by inserting the connector body into the metal enclosure. The polarization keys prevent reverse insertion of the connector body while the contacts make a physical connection between the boards. As the connector body is inserted, the mechanical lock is automatically engaged to keep the two parts firmly together. This ensures a reliable and secure connection between the boards.

The 516-090-000-221 housing is a versatile and reliable backplane connector that is suitable for a variety of applications. It has the capability to handle high power and high-density circuits and is designed with gold-plated contacts to ensure a reliable electrical connection. Additionally, the mechanical lock ensures a secure connection and the design of the connector body prevents reverse insertion. With its versatile design and reliable performance, the 516-090-000-221 is an ideal choice for applications in industries such as telecommunications, aerospace, consumer electronics, automotive, and medical.
