Contacts are the conductive components of a connector, which are used to establish an electrical connection between two circuits. These contacts are typically made of metal, such as copper or brass, and are designed to make contact with a mating connector. Contacts are commonly found in a variety of connectors, such as terminal blocks, headers, and connectors. These contacts can be arranged in a variety of configurations, depending on the specific requirements of the application. For example, some connectors may have only a few contacts, while others may have hundreds or even thousands of contacts.
