Coaxial Connectors (RF) are widely used for radio frequency transmission of signals due to their enhanced electrical performance. DK-621-0440-4P is one of these connectors. It has a 3-piece design which makes it suitable for SMD/SMT mounting on circuit boards. It has a high high-frequency impedance and excellent EMI shielding potentials.
Application Field
DK-621-0440-4P is a type of BNC connector commonly used for connecting coaxial cables, especially in electrical and electronic devices. It can also be used for connecting audio and video cables, and it is suitable for applications such as audio mixers, video cameras, antennas, base station equipment, networking equipment, and other electrical and electronic equipment.
Working Principle
DK-621-0440-4P is a type of BNC connector which transmits RF signals using a bayonet-style locking mechanism. It is composed of three main components – a dielectric-encased center core, a shield, and an outer shell. The center core is the conduit that transmits the RF signal. The dielectric encasing provides a protective barrier against external sources of interference. The shield is used to reduce crosstalk and is typically made of a beryllium copper-based material. The outer shell serves to keep the connector components securely in place. To connect the two cables, the bayonet locking mechanism is used to join the male and female connectors. This locks the connectors together and creates a secure connection for signal transmission.
DK-621-0440-4P is an excellent choice for high-frequency applications due to its strong performance in limiting signal loss, offering improved shielding, and reducing interference. Additionally, its SMD/SMT mounting makes it easier to install on circuit boards.
