Rectangular Connectors HousingsRectangular connectors are connectors that are shaped like a rectangle, and they are commonly used to connect wires or cables to a circuit board or other electrical component. A rectangular connector housing is the plastic or metal casing that encloses the contacts or pins of a rectangular connector. The housing provides protection for the contacts and helps to keep them securely in place, and it also helps to prevent the connector from becoming damaged or malfunctioning. Rectangular connectors and their housings are commonly used in a wide range of applications, including industrial machinery, control systems, and telecommunications equipment.
