Working Principle
The working principle behind the 640503-2 connector revolves around the robust design of the contacts and the receptacle. The contacts are made of tin-plated copper which provides them with the necessary electrical and mechanical properties. The receptacle also has a thermoplastic material that surrounds the contact system, providing a reliable and secure connection. The contacts are arranged in two positions which enable them to provide a high level of current carrying capability. This connector’s low profile design means that it is highly suitable for applications where space is limited, such as in computers, servers and control panels. The 640503-2 also offers a reliable two-piece mating system which ensures a secure connection. The contacts on the two pieces come into contact with one another to create an electrical connection. The two pieces are held together by the use of a grip which is made of an durable thermoplastic material. This grip provides a secure and reliable hold on the two pieces, which means that they will not come apart when in use.
The 640503-2 is a reliable connector for a variety of industrial applications. Its tin-plated contacts provide a high level of current carrying capacity, while its low profile design enables it to be used in tight spaces. It also offers a secure two piece mating system which ensures that the two pieces will stay connected. With its reliable and robust design, it is ideal for a range of applications, from power supplies and motion control systems to robotic systems.
