Backplane Connectors - Specialized - 51939-303 Application Field and Working Principle

The 51939-303 is a specialized backplane connector designed for applications that require high density, high reliability, and low-profile connectors. This connector type has been designed to meet the needs of heavy-duty applications such as industrial control systems, telecommunications systems, and military systems. It is also suitable for applications in medical equipment, avionics, and even consumer electronics.The 51939-303 backplane connector is compact and lightweight, and is capable of accommodating high-density data and power requirements. This connector type is a three-row connector with a receptacle that is mounted directly onto a printed circuit board. This type of connector is designed to provide a maximum of two signal channels and one power channel in each row of the connector; however, additional power channels may be provided if necessary. The two signal channels have a nominal impedance of 100 ohms, and the power channel has an impedance of 12 volts. The contacts are designed to provide the required signal isolation.The working principle of this connector type is based on the idea of positive locking and self-terminating action. The contacts provide the required electrical contact between the mating connector halves and the PCB. The connector is designed to provide minimal contact wear and maximize contact longevity. There are anti-vibration prevents to reduce the risk of damage from vibration and shock.The 51939-303 backplane connector is a versatile connector type that is designed to provide the reliable connection required for high-density applications. The connector is easy to install and is compatible with a wide range of printed circuit board and mounting styles. In addition, this connector type has been designed to meet the requirements of multiple applications and environments, making it an ideal choice for use in a variety of applications.
