Introduction

EHT-122-01-S-D-SM-LC-31 is a type of rectangular connector with male pins. This connector is specifically designed for applications in industrial, automotive, telecom and medical fields. Due to its reliability, efficiency, cost-effectiveness and flexibility, it has become one of the most widely used types of rectangular connectors. It features a high signal density, impedance-matched contacts and an automatic locking system.

Applications

EHT-122-01-S-D-SM-LC-31 is primarily used in a variety of industrial, automotive, telecom and medical fields. It is an ideal choice for applications where a high signal density, improved performance, and good EMI shielding are required such as computers and electronic equipment, communications equipment, high-frequency digital networks, as well as automotive and industrial applications. The connector is widely used in computer systems, in laptops and accessories, and in medical imaging equipment. It is often used as an FXA connector on many electronic products, providing secure connections and robust signal integrity. Additionally, the connector is well-suited for use in power transmission systems, providing reliable power connections while reducing the number of wires and connections needed.

Working Principle

The EHT-122-01-S-D-SM-LC-31 connector follows the same working principles as all rectangular connectors. It consists of two mating parts, the header and the plug. The header is secured by screws or clips to one of the two mating surfaces, while the plug is inserted into the header. The pins on the plug then make contact with the spring-loaded terminals in the header. The header can come in various shapes and sizes to suit different applications. As for the plug, it features a unique locking mechanism that helps to ensure secure connections and is designed to protect the pins from damage or corrosion. The contact points on the plug are also zinc plated and heavily coated with a protective elecronic-grade epoxy for increased durability against dust and moisture. The contacts are specifically designed to have an impedance-matched contact area to provide good signal integrity and reduce external interference and crosstalk.

Conclusion

In conclusion, the EHT-122-01-S-D-SM-LC-31 is a high-quality, reliable rectangular connector with male pins that is suitable for a variety of industrial, automotive, telecom and medical applications requiring improved performance, high signal density and EMI shielding. The connector features an automatic locking system for a secure connection, along with impedance-matched contacts and a heavy-duty protective coating for increased durability.
