Rectangular Connectors - Housings

Rectangular connectors are a type of electrical connection device characterized by two or more sockets coupled together along a flat or rectangular surface. They provide a quick and efficient way to connect circuits and other elements together as part of a larger electrical system or device. Housings are the outer shells that protect the internal components of a electrical connection device.The 2-640251-4 is a housing type rectangular connector made by Grayhill Inc. Specifically designed for applications with up to 10 circuits, it features a metal shell construct with a robust 6-hole ground plane for improved EMF protection. The contact housing comes in two variations, the standard version and the reverse-style version. The standard version features an 11 mm body size with a total of nine mounting holes for assembly, while the reverse version has an 18 mm body size and seven mounting holes for assembly. Both versions have a maximum current rating of 11 A per circuit, with an operating temperature range of -40 to 85 °C.The main purpose of the 2-640251-4 is to ensure dependable, friction and vibration resistant electrical connections in critical applications. It is suitable for use in a variety of fields such as aviation, military, automotive and medical, and can be used to interface with a range of male and female terminals, wires and PCBs.When it comes to the working principle of the 2-640251-4, it involves the use of contact rails that are designed to make contact with the terminals on the mating pieces. The contacts in the contact rails reference each other and touch the mating pieces to create a physical connection in order to transfer electrical power or data. This connection is then made permanent with soldering or other methods depending on the application.The contact rails of the 2-640251-4 are made from beryllium copper and feature pre-tensioning posts and slots to ensure the perfect fit and firm contact with the mating terminals. The contact rails are also designed with beveled ends so that they are able to make contact easier with the mating pieces. This makes it easy to transfer data and helps to reduce the potential of data errors.Finally, the 2-640251-4 housing features a one-piece construction that ensures a reliable and airtight seal. This ensures the correct electrical connection and prevents any foreign material from entering the housing and interfering with the electrical connection. It also helps ensure that the electrical connection remains durable and intact for long periods of time.Overall, the 2-640251-4 is a great choice for applications requiring reliable and robust electrical connections. Its tough housing and rugged contact rails offer superior protection against corrosive or humid conditions as well as providing dependable signal integrity. Its versatile design and pre-tensioning posts and slots also make it ideal for applications with a wide range of mating pieces. Whether you are looking for a dependable electrical connection for a military, medical or automotive project, the 2-640251-4 is a great option.
