A4B-9PA-2DS(71)

Introduction
A4B-9PA-2DS(71) is part of the rectangular connector-headers, male pins family, which is designed for making electrical connections between two pieces of equipment or circuits, enhancing the functionalities of integrated systems, reducing wiring and improving the reliability of these connections. This rectangular connector family is usually applied in large-scale, mission-critical systems, mainly because they provide many advantages compared to other types of connectors; easy to assemble, reliable, compact & cost-effectiveness.

A4B-9PA-2DS(71) Application Field
A4B-9PA-2DS(71) rectangular connector-headers, male pins are mainly applied in huge systems or large-scale devices, where there is a high need of reliability and efficient performance. In such environments, it is very important to avoid possible errors such as accidental disconnection or incorrect assembly. That is why these connectors feature polarizing and guiding elements, such as the latch and guide-pins, which helps for aligning two components correctly. This symmetry adjustment allows for its proper assembly, without fear of interchanging male and female elements or having opposite polarities in opposite directions, so that the integrated system features optimal performance.

A4B-9PA-2DS(71) connectors are usually found in airplanes, radar systems, satellites or in high-end video applications, such as high-definition satellite television. In addition, data-intensive applications such as high-speed serial communication systems, heavy fuel injection systems, X-ray imaging systems and ATM terminals, can also benefit from these connectors. Additionally, certain medical technologies also rely heavily on these connector-headers, such as dialysis machines, pacemakers, and oxygenary monitors. Finally, they can also be used in automotive industries, covering a wide range of electronics, audio system, GPS, computer systems and more.

A4B-9PA-2DS(71) Working Principle
A4B-9PA-2DS(71) Rectangular Connectors - Headers, Male Pins works by allowing a signal current to transmit from a source to a user. These male connectors use a combination of pins and head pins to shape their configuration. Pins are the terminals that look like small blobs, while head pins are the longer parts that look like metal rods. These pins and head pins go into the holes in the devices that require a connection and allow a current to be transmitted from one device to the other. The connectors also provide ground connections to ensure that the current is safely and stably transferred from one device to the other.
A4B-9PA-2DS(71) Rectangular Connectors - Headers, Male Pins features an additional kind of pin: the grounding contact pins. These pins usually mate with corresponding pins from the opposite part of the connector and form an opposing pair, ensuring the current is reliably transferred from one end of the connector to the other. These grounding contact pins are also known as ground pads or earth pins, and they are essential in improving the performance of the connector in many types of systems.

Conclusion
A4B-9PA-2DS(71) Rectangular Connectors - Headers, Male Pins is an easy to assemble, reliable, compact and cost-effective connector family, mainly applied in large-scale and mission-critical systems that require a high level of reliability and performance. They work by allowing a signal current to transmit from a source to a user, featuring pins and head pins that go into the holes in the devices that require a connection. Their most important feature is the addition of grounding contact pins, which mate with corresponding pins from the opposite part of the connector and form an opposing pair, ensuring the current is reliably transferred from one end of the connector to the other.
