Rectangular Connectors - Headers, Receptacles, Female Sockets

Rectangular Connectors are a type of electrical connector widely used for a variety of applications. They are usually found in electronics, automation and control equipment, and many other places requiring electrical connections to be made.

The most common types of rectangular connectors are headers, receptacles, and female sockets. Headers are the most basic type of connector - they consist of two or more pins protruding from an insulated housing. Receptacles are similar to headers, but have a receptacle in the housing to accept the mating connector. Female sockets are the most sophisticated type of rectangular connector and feature two or more female contacts that fit into the mating connector.

Rectangular Connectors are used in a variety of applications. Common examples include robotics, industrial automation, computers, communications, and avionics. In robotics, they are used to provide signal and power connections between the computer and external components such as motors, servos, and other inputs/outputs. In industrial automation systems, they are used to make connections between control panels and the mechanical parts of production equipment.

In addition to their use in various applications, Rectangular Connectors are also widely used in consumer electronics, particularly for audio/video systems. Common examples include RCA and DIN connectors. These types of connectors are used to connect audio/video components such as television sets, DVD players, speakers, and amplifiers to form a complete entertainment system.

The working principle behind most rectangular connectors is simple - electrical current is transferred between two points by metal contacts that fit into the mating connector. Generally, the housing of the connector is insulated to prevent the current from short-circuiting. The metal contacts are either plated with gold or silver, and may also be covered with a thin layer of plastic or other insulating material. The contacts are usually spring-loaded to ensure that they make a reliable connection with the mating connector.

Overall, rectangular connectors are an incredibly versatile type of electrical connector that is employed in many different types of applications. From robotics to consumer electronics, they can be found in almost any industry.
