Application Field and Working Principle of SEAM-20-11.0-S-04-2-A-K-TR

Introduction

SEAM-20-11.0-S-04-2-A-K-TR is a type of rectangular connector array, edge typ, mezzanine (board to board) connector from Samtec. It is a high-density interconnect system, designed to save board space in some end-user applications. This gage size has terminal pitch of 0.063" and terminal count of 200.

General Features

This connector offers a number of features that really make it useful in applications. The integrated solid-body housing is designed for tight, secure push-in mating. This connecter also has a simple keying feature which makes sure that mating takes place correctly and quickly, with the male and female parts arranged securely. It also has a quick mating and unmating system, with a simple to use anti-slip mechanism for added security during mating.

Application Areas

This connector has a wide range of applications. It is suitable for use in a variety of different development boards, especially those with high-speed connections. In these applications, the connector provides a reliable and secure connection between boards, enabling efficient and uncompromised data transfer. It is also suitable for use in switching devices, routers and other devices which require high availability.

Working Principle

The SEAM-20-11.0-S-04-2-A-K-TR connector works on the principle of electrical snap-action. This is a type of electrical mechanism that can rapidly open or close a contact when acted upon by an electrical signal. The connector uses contact plates on either side of the housing which mate when sufficient electrical current is supplied. This current not only ensures that the connection is established, but also provides a secure snap-action connection that maintains contact while in use.

Conclusion

In conclusion, the SEAM-20-11.0-S-04-2-A-K-TR connector is an ideal connectivity solution for high-speed applications that require space saving, reliable and secure board-to-board connections. The snap-action connection principle ensures that the connection is always secure, while the quick-mating and unmating system makes the connector far easier to use than traditional connectors.
