51939-147LF connectors are specialized backplane connectors. These types of connectors are commonly used in various electronic applications, such as networking, automotive, aerospace, industrial machinery, and defense-related systems. They are manufactured with robust designs to facilitate the interconnection of various PCBs or boards in densely packed applications.

The 51939-147LF connector can be seen as a specific type of backplane connector. It is a 4 row 50-way array connector with positioning keys. This connector has two mounting options: through-hole or surface mount. Its housings have 0.1” spacing between contact pins. It also features two pin and socket contacts with a current rating of 10A. This connector was designed to meet the 51939 standard established by the Contact Manufacturer’s Association.

The working principle of the 51939-147LF connector is fairly simple. It is composed of two parts: a housing and a set of contacts. The housing is made of thermoplastic elastomer and it serves as the base for the connection pins. Its job is to position and secure the contact pins. The contact pins are made of beryllium copper and they have a 4mm square configuration. The contact pins make and secure the electrical connections, which in turn facilitate the flow of electrical signals. The contacts also provide power and data transmission capability between two or more boards. This connector is capable of transferring high speed signals.

The 51939-147LF connector is used in a wide variety of applications. It is commonly found in automotive, jet engine, air traffic control, and telecommunications applications. In machining systems, these connectors are used to connect boards in order to maintain efficient communication between multiple machines and parts. They are also used to interconnect multiple boards in a single system, such as to control the working order of different parts or assemblies. Additionally, these connectors are used in ruggedized and highly reliable military-grade system designs.

In summary, the 51939-147LF is a specialized backplane connector. It is composed of a thermoplastic elastomer housing and beryllium copper contact pins. This connector can be used in a variety of applications, such as in machining systems, automotive, jet engine, air traffic control, and military-grade systems, and its primary purpose is to provide power and data transmission between boards. The working principle of this connector is based on the contact pins making and securing electrical connections, which facilitates the flow of electrical signals.
