Rectangular Connectors – Headers, Male Pins provide communication between electronic circuits, and include male headers with a variety of pin shapes, number of pins, and orientation options. The 68016-420 is a right-angle male header with 36 pins, for densely populated PCBs. Here, we discuss the application field and working principle of this component.

Application Field

Thanks to its right-angle configuration, the 68016-420 cable support simplifies the PCB design, as there is less interference with other elements. It is particularly suitable in applications requiring high pin counts and/or board-level debugging, such as multilayer boards and very-dense systems. Some applications of this component include:

• Medical imaging equipment, such as heart monitors, CT and MRI scanners, and more.
• Automotive electronics, including in-vehicle entertainment systems, sensors, and control units.
• Industrial automation equipment, as well as robotics.
• High-end consumer electronics, such as Blu-Ray players, gaming consoles, and set-top boxes.

Working Principle

The two principal components of the 68016-420 connector are the male contacts and the PCB hole/pad matrix. The pin contacts are made up of copper alloy and are soldered to the board, while the receptacle contacts are mated with the soldered header pins. The principal working of the connector follows the steps below.

1. The male pins of the 68016-420 connector are soldered onto the circuit board. At this point, the connector is ready to accept a mating component.
2. A mating component is fitted into the connector. This process is designed for low insertion force, and the contacts are designed for repeatable mating (so the same connector can be used multiple times).
3. The interconnections of the contacts facilitate low-loss signal transmission through the connector.
4. When the component is unplugged, the surface tension of the contacts keeps the pins from coming out of their PCB holes or pads. The male pins can be easily soldered anew in case they become loose.

Conclusion

The 68016-420 right-angle male header is designed for tight-space PCB applications, where space, signal loss, and cost are key considerations. Its male pins are soldered onto the board, and its low insertion force and repeatable mating capabilities make it easy to use, and suitable in a wide range of applications, from medical imaging, automotive electronics, and industrial automation. During its working, the contacts facilitate low-loss signal transmission, and the pins remain securely in place even when a component is unplugged.
