Circular Connectors - Contacts is one of the most commonly used connection devices in modern electronics. As an essential component of modern electronic systems, they provide the specification of physical interface and performance. The way they are constructed to form the physical connection between multiple systems requires careful consideration and engineering to optimize their performance and capabilities for specific applications. One of the most well known and commonly used circular contact connectors is the SA3179.

The SA3179 is a 3-pole, circlular contact connector designed for the transmission of digital signals typically found in industrial and instrumentation applications. The connector uses the signal contact arrangement of 1-3-2, where the center contact (Pin 2) is both the shielded and grounded part of the connector. It is an inexpensive solution and is designed for use where multiple signals are combined or isolated.

The SA3179 is well suited for applications where high density of internal circuitry is required and also for applications where there is a need to provide power and ground isolation. It can also be used for situations where signal transmission noise is a concern. The contact pitch is 2.54mm with rated contact current of up to 6A. The connector meets NEMA, UDEL, UL, CSA, IEC, DIN, and JIS standards and is fully shielded to provide EMC/RFI shielding.

SA3179 features robust design with a corrosion-resistant shell, and is able to survive vibration, dust and chemical exposure. It has an operating temperature range between -25 and +70°C, so it is suitable for a wide range of application conditions. The connector can mate with or without the use of a complimentary locking device such as a grommet or bracket.

At a basic level, the working principle behind the SA3179 is that it provides a physical contact point between multiple items in an electrical system. The connector allows external controllers, motors, and other devices to be connected together and share power or signal data. Once the connector is firmly mated to its counterpart, the contacts establish a path between each item for data to flow through. This enables real-time communication for automation and control systems used in a wide variety of industries.

The SA3179 is an effective, reliable, and affordable way to connect multiple electronic systems. It provides the electrical and mechanical requirements needed for optimized performance in a wide variety of applications. The connector is available in a variety of sizes, with a wide range of mating options. This cost-effective solution offers a high degree of flexibility and is suitable for both industrial and instrumentation applications.
