TM-M-128-01-TM-S-RA-018, commonly referred to as the RA, is a rectangular connector header that has male pins. Variable pitch options, ranging from 8.0 mm to 2.1 mm, and different termination types allow the RA to be used in multiple and versatile applications. This connector is suitable for companion boards and board stacking, meeting the parameters of various market requirements. The integrated design and superior structural integrity accomplish superior and reliable electrical contact.

Design and Connectors

The RA is designed with rectangular shape and contact points for plugging and unplugging. It is housed in grey colored plastic and has a raised locating shoulder with snap indents. The components of this male header are shuttered contacts that can install 1–125 contacts with a variable pitch option. The terminals are formed with beryllium copper metal sheet with a gold-plated finish on them. The product is mechanically structured with self-indent pins, which allow efficient and secure board-to-board contact and interconnecting.

Working Principle

When the header is plugged into the corresponding mating receptacle, the pins and sockets get engaged, ensuring and increasing the contact force. The self-indent pin in the RA headerv seals the connection from the involuntary stirrup effect, dirt, and debris, which deters connectors from making contact with dirt and debris. The angle of the connector pins is designed to increase force against the mating socket and fastener, creating a secure mechanical connection between the two.

Applications

The RA is widely utilized in computer and communication applications, like PC peripherals, computer backplanes, SFFs, control boards, electronic packaging, and so on. One of the primary applications of the RA header is connecting two boards. This connector type has also been used in the medical and consumer electronics industries, making it a great solution for medical-grade equipment and consumer products that require reliable connections. Additionally, it is also widely used in traffic, military, and aerospace applications.

The RA connector header is an ideal choice for those looking for reliable connections that have minimal chances of failure and could easily facilitate PCB or board-to-board connections. Its multi-pitch and termination type features provide it with the versatility to fit the varied requirements of customers. Its self-indent pins create a secure connection and keep cables from becoming loose and falling out.
