Introduction to 51939-220:51939-220 is a special type of backplane connector that is used to interconnect boards in a chassis-style system, such as a server, computer system or broadband communications system. This type of connector is designed with modularity in mind, allowing for the different parts of the system to be connected and disconnected easily. The 51939-220 backplane connector is also commonly referred to as a “stacked” connector, because it can be easily removed and re-stacked in multiple configurations.Application Field and Working Principle:51939-220 backplane connectors are used in a wide variety of applications, including servers, personal computers, networking equipment, medical devices and more. These connectors have become increasingly popular due to their small size, durable construction and flexibility.The 51939-220 connector features staggered contacts that are spaced apart according to their respective sizes. This ensures that the connector’s performance remains consistent, regardless of the board configuration or type of signal that is being transferred. The staggered design also allows for the use of multiple boards in a stacked configuration, which can provide significant advantages.A key component of the 51939-220 connector is its insulation. This insulation protects the connector from electricity, which can cause damage, or interference with the signal transmission. This insulation is also used to reduce the amount of thermal energy that is lost to the environment, making the connector more efficient. Additionally, this insulation helps protect the connector from the external environment, such as moisture and dust.The 51939-220 backplane connector is also designed for a specific type of signaling, which is EMI protection. EMI (electromagnetic interference) is a problem in many electronic devices and can affect the overall performance of the system. This is why the 51939-220 connector is designed to reduce the amount of EMI that is emitted from the system.Overall, the 51939-220 backplane connector is a reliable, durable, and efficient solution for interconnecting boards in a chassis-style system. It is designed for easy installation and removal, and is able to withstand the rigors of day-to-day use. Additionally, the insulation provides the connector with additional protection against hazards such as moisture and dust, allowing the system to run efficiently and effectively.
