MDF7-17S-2.54DSA(55) are rectangular connectors that belong to the Headers, Receptacles, Female Sockets sub-family. Taking a closer look, they specialized in transmitting signals and providing secure electrical connection between two distinct electronic components, or multiple device ports. In terms of form factor, they accomodate a maximum of 55 contacts based on the Dimensions of the rectangular housing at the back, and the IC Socket of the male/female component that connects to them.

They are typically found on automotive, military, and industrial equipment, and benefit from strong contact force and low insertion and withdrawal force. Besides reliable contact resistance, these components also feature precision spring contact pins that are designed to have minimal contact resistance variation even after numerous connection cycles. This ensures that the connector performs reliably in harsh environments, and deliver high-speed signal transmission that is needed in demanding applications.

MDF7-17S-2.54DSA(55) can work with different types of cable and housing. For example, it can be used with a Micro-Fit DNA/MATE-N-LOK cable with an associated MDF 7-17S-2.54DS housing. Furthermore, these connectors are also compatible with different types of external locking devices, such as backplane adapters, compression lids, PCB support pins, and more.

In terms of the working principle, MDF7-17S-2.54DSA(55) connectors are typically built with four separate components: the body, the contact, the insulator, and the insulation. The body is generally made of aluminium alloy and provides the mating interface for the pins. The contact pins are usually made of copper and helps provide a strong electrical connection. The insulator is typically made of plastic material and provides the physical ‘spacer’ between the body and the contacts. The insulation is the actual ‘housing’ that provides protection from the elements and helps ensure the connector is securely held in place.

All of these components work together to provide a reliable, high performance electrical connection. As the contact pins are inserted into the pins of the connector, the pins create a secure electrical connection while the insulator provides stability and the insulation helps protect the integrity and longevity of the connection.

In conclusion, MDF7-17S-2.54DSA(55) are an ideal solution for both industrial and automotive applications due to their strong contact force, low insertion and withdrawal force, and precision spring contact pins. Their components (body, contact, insulator, and insulation) also work together to ensure reliable, high performance electrical connections in even the harshest of environments.
