TMM-105-04-LM-D-SM-A Application Field and Working Principles

Rectangular connectors play an important role in various electronics fields, from industrial to consumer. The TMM-105-04-LM-D-SM-A connector is a widely used rectangular connector, widely used for applications in fields such as consumer electronics, military, aerospace, and automotive. This connector comes in two variants—the header pins and male pins—which can be used for connections in high-density applications. This article explores the application field and working principles of the TMM-105-04-LM-D-SM-A connector.

Application Field

The application field of TMM-105-04-LM-D-SM-A connectors can be seen in various electronics and machinery fields, from small household consumer products to large industrial machines. While the exact application of the connector depends on specific requirements, this connector is commonly used for boards with higher densities and is great for connecting internal circuits, as well as connecting several PCBs together. Apart from that, the TMM-105-04-LM-D-SM-A connector is also suitable for use in equipment that requires high-voltage and/or EMI shielding. Some of the typical application scenarios of this connector include motor controllers, automotive control units, industrial automation systems, etc.

Working Principle

The working principle of the TMM-105-04-LM-D-SM-A connector is simple but effective. The header and male pins each feature a raised, U-shaped contact that is designed to hold onto the other side of the plug firmly with precise pressure. As the connector is pushed onto each side of the plug, the U-shaped contacts press firmly against the sides of the plug, providing an electrical connection. This design helps reduce the chances of any loose connections, especially in high-density applications.

Also, the TMM-105-04-LM-D-SM-A connector utilizes a special mating system known as ‘floating’ or ‘clamping.’ This system is based on two grooves within the connector, which helps improve the mating angle and force between the contact elements. The mated connector can also be easily disassembled at any time.

The TMM-105-04-LM-D-SM-A connector is also designed with an anti-static design, which prevents the connector from transferring static electricity to the internal parts. This helps protect the internal components from any potential damage.

Finally, the TMM-105-04-LM-D-SM-A connector is RoHS and EMC compliant, meaning it does not contain any hazardous or environmentally harmful materials. It is also tested against a wide range of temperatures and other environmental conditions to ensure its durability and long-term reliability.
