D-Sub Connectors

D-Sub connectors, also known as ”D-Sub” or ”DB” connectors, are circular connectors used to join two or more circuits together. They have two main parts: an outer shell and an inner contact assembly. The outer shell provides protection against environmental conditions such as EMI/RFI, dust, moisture, and extreme temperatures. The inner contact assembly provides the connection between the two circuits.

The 172-E09-112-021 connector is a high-performance version of the standard D-Sub connectors. It features small size, rugged construction, superior shielding, improved connection quality, and increased throughput speed. It is typically used to establish a reliable connection between two circuits.

Applications

The 172-E09-112-021 connector is used in a wide variety of applications, including industrial automation, consumer electronics, automotive, telecom, and aerospace. It is a reliable and cost-effective way to establish connections in environments where EMI/RFI, shock, and vibration are expected. It is also used in medical equipment, scientific instruments, and test equipment.

Working Principle

The 172-E09-112-021 connector is capable of both digital and analog signals. It works by establishing an electrical connection between two circuits. The connection is made through an electrical contact on the shell and a corresponding contact on the inner contact assembly. The electrical connection is then secured and kept in place by mechanical features such as screw-type, metallic clips, or spring fingers.

The 172-E09-112-021 connector is designed to ensure a consistent and reliable connection. It features a robust metal shell that provides excellent shielding against EMI, RFI, shock, and vibration. The inner contact assembly is designed with precision and features a built-in contact spring to ensure a low contact resistance. The contact spring also offers superior stability over time and high mating cycles.

The connector is designed to be compatible with a variety of mating configurations, such as straight, offset, and 180 degree angles. In addition, it has an internal keying system to ensure a secure connection. The shells are usually made of zinc or aluminum and are available in various colors.

Conclusion

The 172-E09-112-021 connector is a reliable and robust solution for connecting two circuits. It is designed to deliver high performance and reliability in harsh environments. It features a robust shell and inner contact assembly for superior shielding and connection quality. It is easy to install and is compatible with a variety of mating configurations. This makes it a cost-effective and reliable solution for connecting two circuits.
