Backplane Connectors - Specialized

The 51939-171LF is a specialized backplane type connector from a popular maker of electronic components. As its name implies, it is specifically designed to provide reliable signal transmissions between a backplane and its ICs. As one of the largest manufacturers of active and passive electronic components, their products are designed to meet the reliability and performance criteria of leading edge applications.The pin and socket contacts are gold plated with an overall length of 1.45mm and a contact spacing of 0.8mm. The component body is machined from stainless steel and the properties of the contact materials are such that they have excellent EMI/RFI protection and are able to meet the most stringent temperature range requirements.Being of the backplane type, the connector is used to provide interconnects between PCBs and boards assemblies that form an integrated system. Designed for high density applications, the 51939-171LF is used widely in the telecommunications, computer, medical, military and commercial markets.A key feature of this specialized backplane connector is its signal integrity. The connectors provide reliability of signal transmission, low cross-talk, power integrity, high return loss and ESD suppression. This is achieved through a combination of design, technology and good material construction.The connection interface comprises of two contact elements - the socket and pin. The pin connection is securely held in place and allows for blind mating. The socket connection provides exceptional EMI/RFI protection with its spring fingers maintaining electrical contact pressure.The 51939-171LF is designed for applications where space is at a premium, and as such, its board-to-board spacing is just 4mm. This small surface-mount design also minimizes the loads placed on the PCB and the footprint of the device itself.The maximum operating voltage of the connector is 50V and its current rating is 5A. This makes it suitable for applications requiring low voltage and low current connections.When it comes to installation, the 51939-171LF is easy to handle and assemble. Its press fit design requires no special installation tools and makes it easy to install on the backplane. The insertion force of the pins is less than 0.2N, meaning that it will not cause damage to the PCB.In conclusion, the 51939-171LF is a specialized backplane type connector that is designed for reliability and performance in an array of applications. Its compact design allows it to be used in densely populated areas without compromising on quality. With its low current, low voltage specifications, and easy installation, it is the perfect choice for a wide range of devices.
