The 65780-004, widely used in industrial, commercial and military applications, is one of the most reliable and versatile rectangular connectors. It is a component of the Headers, Receptacles, and Female Sockets family and it has a distinct form factor that makes it ideal for connecting components in applications where space is limited. This article explains the 65780-004\'s application field and working principle.

The 65780-004 is a right-angle, board-to-board connector with an enhanced contact design and a PCB footprint that is only 5.08mm x 6.35mm. It is perfect for signal, power, and data transfer in industry and military applications, such as in telecommunications, scientific testing, and robotics. Its normal maximum rated current/voltage (in amps/volts - AC/DC) is 5.0A/125VAC, 7A/120VAC, 0.3A/30VAC; and it has a maximum operating temperature of +105°C. The 65780-004 is available in a variety of pin lengths and configurations, with a range of 1 to 31 pins, and its pitch size is 0.1” (2.54mm). The connector has a rated current of 0.3 A per line, a contact resistance of 0.1ω maximum, and a dielectric strength of 1, 1000 VAC.

The 65780-004 is a two-piece rectangular connector. It consists of an insulating base and a mating header that is soldered into a printed circuit board (PCB) and a mating header that directly contacts pads on the PCB. There is a key in the header position that prevents it from being inserted in the wrong way. The contact system consists of two metal plates held together by a metal strip, an insulator, a pin, and a spring. This creates a secure, reliable connection, allowing for high-speed signal transmission and eliminating the need for conductive tape.

The two pieces of the connector, the header and the receptacle, come together to form a cylinder, with the headers and the receptacle abutting each other. The connection is made when pressure is applied, driving the pins of the header into the receptacle openings. This compression creates an electrical connection, allowing current to flow between the two components. As the pins enter the receptacle openings, a mechanical lock prevents them from withdrawing, ensuring that the two components remain connected after the pressure is released.

The 65780-004 connector is easy to install and reliable. It has a low insertion force and good backout characteristics, meaning that it can withstand the mechanical shock and vibration of use. The connector pins have a gold-plated finish, which protects them from corrosion and ensures reliable electrical contact. The 65780-004 is also UL recognized and CSA certified, ensuring safety in high-voltage applications.

In summary, the 65780-004 is a versatile and reliable connector that is perfect for a variety of industrial, commercial and military applications. It has an enhanced contact design, a low insertion force, and a wide range of pin lengths and configurations, making it ideal for applications where space is limited. Furthermore, its gold-plated finish and UL and CSA certifications make it safe and reliable for use in high-voltage applications.
