Introduction to D-Sub Connectors

D-Sub connectors are a range of electrical connectors utilizing a three-layer design with two parallel rows of pins. They have been used for decades for commercial and industrial applications, ranging from home theatrical systems to computer networking to railroad signaling. They are also popular among hobbyists and makers due to their low cost and availability.D-Sub connector types vary in number of pins and size, ranging from 14 pins to over hundred. They can also be used to carry both signal and power in high-speed or DC applications. D-Sub connectors are universally accepted due to their long-term reliability and lack of complexity.

172-E37-101R031: Application Field and Working Principle

172-E37-101R031 is a 37-pin miniature D-Sub connector made by Amphenol. It is commonly used in applications such as consumer electronics, test and instrumentation, and high-speed communication between two devices.The 172-E37-101R031 is designed with a 2.54mm pitch, which allows for up to 37 connections in a space-saving package. It features high-reliability contacts and a durable shell material, making it suitable for regular handling and rough environments. It also features a locking mechanism that provides a secure connection between the two devices.The working principle of the 172-E37-101R031 is simple. It uses a cantilever-style contact system with high resistance to shock and vibration. The contacts are made of beryllium copper or phosphor bronze with a tin plating, which provides excellent electrical and mechanical performance. The contacts are also arranged in an alternating pattern on both sides of the shell, thus minimizing the space used.The 172-E37-101R031 is a cost-effective connector solution and offers excellent signal quality. It is especially suitable for high-speed applications such as HDMI, Serial ATA, USB, and 10 Gigabit Ethernet.
