Introduction

The ESS-104-G-27 is one of the most common types of rectangular connectors designed and manufactured for a wide range of applications in both industrial and consumer electronics. This connector type is sometimes referred to as "headers," "female sockets" or "receptacles." This type of connector is preferred for demanding applications requiring superior electrical performance and high durability, such as high-speed data transmission or board-level interconnects.

Design and Characteristics

The ESS-104-G-27 is a 2-piece, non-polarized and double-ended connector designed to fit together effortlessly. It consists of an upper part called the “header” or “plug” which contains two right-angle, angled pins arranged in a rectangular pattern, and a lower part called the “receptacle” which securely holds and aligns the pins. Both, male and female components are made from high quality, corrosion resistant materials and are available in single row, two-row and four-row configurations. The ESS-104-G-27 can be used with varying contact counts from 2 to 12, with a gold plated brass or tin-plated brass pin. It can handle a wide range of operating temperatures from -25°C to +85°C, making it suitable for various applications. The electrical characteristics provide superior shielding and low resistance, thanks to an insulation resistance of 40 MΩ minimum at 500V AC, a current rating of 2 A and a contact resistance of 28 mΩ for gold plated and 30 mΩ for tin-plated versions.

Application Field and Working Principle

The ESS-104-G-27 is used in a variety of electronic equipment and instrumentation applications which require robust and reliable performance. Examples include aerospace, automotive, telecommunications, military, telecommunications, medical, test, and instrumentation applications. For aerospace and military applications specifically, the ESS-104-G-27 is not only suitable for flights and exposed to extreme temperatures but also highly able to endure vibrations. For telecommunications, automotive, and medical applications, the strong electrical connection allows reliable data transmission at high speed without interference and ensures precision and accuracy.The connector works by bringing both of its components together in a secure attachment process. Both parts are firmly connected through a mechanical force. This ensures that the electrical connections between the contact pins remain intact and interference is avoided. The connector’s latch ensures that the two parts stay secured together even in high-vibration and temperature environments.

Conclusion

The ESS-104-G-27 is a latching, double-ended rectangular connector designed for a wide range of application fields requiring high electrical performance and reliability. Its mechanical and electrical properties make it well suited for use in demanding aerospace, automotive, medical, and telecommunications applications. The connector offers superior shielding and low resistance, a wide operating temperature range, and a secure latch that ensures that the two parts stay connected in various environments.
