IntroductionThe BM20B(0.8)-50DS-0.4V(51) is a state-of-the-art, high performance rectangular edge-type mezzanine connector system. It is designed as a compact alternative to larger board-to-board connectors for applications where size and cost are primary considerations. The BM20B(0.8)-50DS-0.4V(51) is ideal for use in many industries and applications where it provides a reliable connection and robust performance in a wide variety of environments.Application FieldThe BM20B(0.8)-50DS-0.4V(51) is ideal for applications in which the need for higher performance, smaller packages, and lower cost are paramount. This connector system is designed for applications in which speed and precision are critical. It is well suited to use in data networks, telecommunications, medical devices, automotive electronics, test & measurement systems, and industrial automation. This system can also be used in rugged applications in which sealing, shock and vibration, or humidity are considerations.Design CharacteristicsThe BM20B(0.8)-50DS-0.4V(51) has several key design features that make it a great choice for many applications. The connector offers a wide range of power and data combinations, making it suitable for digital, analog, or mixed-signal designs. It also features a non-slotted, double-block design that enables an even load distribution across the mating interface and ensures reliable contact pressure. Additionally, the connector provides a low profile that allows for minimal space requirements, yet offers robust performance and reliability. The connector’s gold-plated contacts and contact carrier provide excellent contact integrity and electrical performance. Working PrincipleThe BM20B(0.8)-50DS-0.4V(51) utilizes a double-block contact system that provides an extremely robust design. The double-block construction consists of two sets of contact blocks, one set for electrical contact and the other for providing mechanical integrity. The electrical contacts securely fit into the board’s plated-through holes and ensure a reliable electrical connection. The mechanical portion of the connector provides a secure, low-profile connection that is capable of withstanding shock and vibration as well as providing a seal against dust and other elements. The connector has been designed to reduce the possibility of contact misalignment, which can cause intermittent connections, and to provide a secure and reliable electrical connection.ConclusionThe BM20B(0.8)-50DS-0.4V(51) is a reliable, high performance rectangular edge-type mezzanine connector system. Its compact size and small package make it ideal for applications in which space is limited. The connector is well suited to data networks, telecommunications, medical devices, automotive electronics, test & measurement systems, and industrial automation, or for demanding applications in harsh environments. Furthermore, it utilizes a double-block contact system that provides an extremely robust design, capable of providing a secure connection and reliable electrical performance.
