Introduction

The TMM-118-01-S-S-SM is a type of rectangular connector from the Headers, Male Pins modular connector family. It is typically used in small electronic devices and comes in two main variants: straight or right-angle. This particular connector is specially designed to be used in applications with stringent requirements on durability and ease of assembling, such as test systems, communication systems, and data acquisition systems.

Description and Specifications

The TMM-118-01-S-S-SM rectangular connector is composed of two mating parts, a male pin header and a female socket. The exterior dimensions of the male pin header are 0.118 inches x 0.013 inches, while the female socket has a rear cut-out size of 0.162” x 0.065”. This connector is part of the rectangular Through Hole (TH) Modular Connector family, and is designed for use with TH-type printed circuit boards (PCBs).The TMM-118-01-S-S-SM is made of phosphor bronze with gold plating and supports signal voltages up to 50 VDC. It features environmental protection of IP20, and a contact rate of 2A. The operating temperature range of this connector is between -25 to 85 °C with a maximum current rating of 3A.

Application Field and Working Principle

The TMM-118-01-S-S-SM connectors is suitable for a range of applications, such as test systems, communication systems, and data acquisition systems. It can be used to connect signal lines in such systems, as well as to provide power and ground connections.The mechanism of the connector works by inserting the male pin header into the female socket. Once inserted, the pins are held securely and the connection is established, making it an ideal choice for low-profile applications. The gold plating on the pin connectors provides superior protection against corrosion, making it suitable for harsh environmental conditions. Furthermore, the connector offers excellent contact force retention and low insertion force, thereby reducing connection errors and ensuring reliable data connections.

Conclusion

The TMM-118-01-S-S-SM rectangular connector is a versatile and reliable option for connecting signal lines in various electronic systems, such as test systems, communication systems, and data acquisition systems. It is made of high-quality materials, is easy to assemble and offers superior protection against corrosion. Additionally, the connector offers excellent contact force retention and low insertion force, thereby reducing connection errors and ensuring reliable data connections.
