Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board)

The FX4C-40S-1.27DSAL(71) connector is a mezzanine array board-to-board connector. It is used to connect two electronic boards in mezzanine applications, such as embedded systems, small computing systems or industrial equipment. It has a maximum voltage rating of 250VAC/VDC and can handle up to 5A of current.

It features 40 rows of pins in a 2x20 array and provides a mating face of 0.025 inches in pitch. The pins are made of tin plated phosphor bronze with a diameter of 0.0153 inches and the dielectric strength is 1KV RMS. The contact resistance is 10mΩ and the insulation resistance is 1GΩ.

The base material is polyester and the contact plating is gold over nickel. The connector is RoHS compliant and comes with a UL 94V-0 flame retardance rating. It is designed to meet IP67/68 and NEMA 6/6P standards.

The working principle of the FX4C-40S-1.27DSAL(71) connector is to use two parallel edge boards into which the pins or contacts of the connector are inserted to form a low resistance electrical connection. The pins are connected to the boards using connectors (also known as headers) which can be either soldered or mechanically fastened. The mating contact of the connector is then inserted into the board mounted connector and the two are then pushed together to form the electrical connection.

The advantage of using this type of connector is that it is much faster than soldering and requires less space than traditional mechanical connections. The design also ensures that the connection is secure and resistant to vibration, shock and temperature changes. Additionally, due to its design, it can provide more reliable and quicker connections than other types of connectors.

The FX4C-40S-1.27DSAL(71) connector is often used in embedded systems, small computing systems, industrial control panels and other mezzanine applications.

Overall, the FX4C-40S-1.27DSAL(71) connector is an excellent choice for mezzanine applications, providing a fast, reliable and secure electrical connection in the smallest of spaces.
