Backplane Connectors - Hard Metric, Standard

PCN21B-55SCA-2PF Application Field and Working Principle

PCN21B-55SCA-2PF is a type of backplane connectors developed by Tyco Electronics. It falls into the “hard metric” category of connectors, which are designed to be resistant to mechanical and electrical shock. This type of connector has a wide range of applications in communications, automation, fiber optics, and various other industrial applications.The PCN21B-55SCA-2PF backplane connector consists of a metal shielding element, a signal contact system, and a locking system. The shielding element protects the connector from external interference and is made of nickel-plated copper. The signal contact system consists of a center contact pin, two side contacts, and two spring-loaded protective sleeves. The locking system uses two locking pins to secure the connector into its mating socket.The working principle of the PCN21B-55SCA-2PF backplane connector is relatively simple and straightforward. When the connector is inserted into the mating socket, the two locking pins click into place and create a secure and reliable connection. This connection is protected by the shielding element and the spring-loaded protective sleeves, which absorb shock and vibration. The center contact pin and side contacts carry the signal within the connector. The copper compound of the connector provides good conductivity and minimizes interference.Overall, the PCN21B-55SCA-2PF backplane connector is a reliable and resilient solution for a wide range of applications. Its design ensures good electrical conductivity and provides effective shock and vibration protection. Its locking system ensures a secure connection and its signal contact system provides a stable data transmission. As a result, the PCN21B-55SCA-2PF is a perfect solution for industrial applications that require reliable data transmission and protection from electrical and mechanical shock.
