DF17(4.0)-20DS-0.5V(57) is a type of rectangular connector that is part of an array, and falls into the edge type, board-to-board mezzanine connector family. This family is often used in the medical industry and computer motherboards, as the design features a low height and a number of additional pieces of security to ensure a reliable connection.

The DF17 series is a 0.5mm pitch connector, meaning the lead connections are spaced 0.5 mm apart. This tiny distance provides a very high density of contact in a small space. The edge type connectors have a spacing of 8.2mm so multiple connection can be easily made down a board. These connectors are 28mm in length and 8mm in width. The base material is liquid crystal polymer, which provide an efficient weight ratio and exceptional durability.

The DF17 series is available in several standard variations with mounting heights ranging from 3.2mm to 6.3mm, and with as many as 50 pins. The configuration features stainless steel shells with either horizontal or vertical orientations. They are compliant with high reliability solutions such as medical and automotive requirements and can withstand temperatures up to 125°C.

When used in the medical industry, the DF17 connector enables a wide range of diagnostic equipment such as medical imaging, X-ray, multi-sensors, monitoring devices, and lab devices. Its small size also makes it suitable for wearable devices, and compact medical implants.

In terms of working principle, the DF17 connector is designed to securely connect two boards together via pins and sockets. It is manufactured with a plastic insulator that can accept lead terminals and come with features to increase the mating accuracy such as presses fit and insert molding. The plastic insulator also keeps the board and PCB separated by a certain distance, preventing damage to sensitive components. The strength of the connection is further enhanced by latches that secure the mated parts together.

Overall, the DF17(4.0)-20DS-0.5V(57) is a reliable and durable type of board to board rectangular connector. This edge type mezzanine connector is designed for applications in the medical and computer industries, and features a low height and a variety of additional security features to provide a strong and secure connection.
