BM25-4S/2-V(53) is a type of Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board). It is designed for connecting two boards together with a strong current capacity and a high frequency connection. This type of connector offers a range of benefits that help ensure a reliable and robust connection.

Application Field

The BM25-4S/2-V(53) is designed to be used in a variety of applications. It is a strong choice for medical, industrial, and avionic applications due to its high-speed connection and large current-carrying capacity. It also offers high-fidelity data transmission that allows it to be used in applications such as digital signal processing, optical communication systems, as well as high-speed analogue signal transmissions. This connector is also a popular choice for high-density board-to-board applications, including mezzanine systems, robotics, and automation.

Working Principle

The BM25-4S/2-V(53) is a type of mezzanine connector, meaning that it is designed to connect two printed circuit boards together. The connector has a tab along the top edge that slides into a mating board, and contacts are machined to fit the two PCBs to ensure a reliable connection. The connector also features four board layers and two rows of solder tails which offer increased current carrying capacity.

The connector is held in place mechanically by two screws or an optional snap-in clip. This ensures a robust connection against any shock or vibration. The connector is also designed with a large gap between the tail end of the connector and the PCB so that any flux residue or solder can be removed without causing contact damage.

The contacts of the BM25-4S/2-V(53) are made of contact-rated gold plated beryllium copper and are designed to ensure reliable, low-resistance connections with low-resistance mating. The contacts also feature an electroless nickel over gold plating which helps to improve environmental stability. The contact forces of the connector can be adjusted easily by turning the two screws to the desired settings.

Conclusion

In conclusion, the BM25-4S/2-V(53) is a type of mezzanine connector that is designed for connecting two printed circuit boards together and offers a range of benefits that allows it to be used in a variety of applications. It features two rows of solder tails that offer increased current carrying capacity, and its contacts are designed to ensure reliable, low-resistance connections with low-resistance mating. The connector is also held in place mechanically by two screws or an optional snap-in clip to ensure a robust connection against any shock or vibration.
