STMM-115-01-G-D-SM Application Field and Working Principle

As a part of the rectangular connector family, STMM-115-01-G-D-SM is mainly used in the automotive, military and aerospace industries. This style of rectangular connector is typically constructed with multiple pins and a short molded body, which makes it ideal for transmitting data and power in tight spaces. This type of rectangular connector is useful in various applications like medical equipment, harsh environment and high temperature applications where size and weight are important factors and must be kept to a minimum.

Overview

The STMM-115-01-G-D-SM consists of a male-end connector and plastic body with through hole-type mounting. The male end contains a number of pins arranged in a straight line and are designated by a standard numbering system. The connectors can also be stackable using either the SMT (surf mount technology) or THT (through-hole technology) varieties. The male end also includes an over-molding that helps protect the pins from damage. Its relatively low profile design allows the use of multiple connectors without worrying about stacking them too close together.

Applications

The applications involving STMM-115-01-G-D-SM Rectangular Connectors - Headers, Male Pins mainly include automotive, military, and aerospace industries where tight spaces need to be filled. Additionally, this style of connector is becoming increasingly popular for use in a variety of other applications, such as medical equipment, harsh environment, and high temperature applications where size and weight are important considerations. The header style also allows for ease of use and faster installation due to its easy snap-in design.

Working Principle

STMM-115-01-G-D-SM Rectangular Connectors - Headers, Male Pins mainly use a standard design consisting of an insulated thermoplastic outer body, a PCB terminal and a socket connector. The pins are then inserted into the body which is fitted with the socket and the conductor is shielded inside the outer body. The pins are so arranged that power and data is transmitted from the host device to the mating section. A locking mechanism is used to ensure a secure fit between the two parts.

The most common insulation materials for these connections are PTFE and 100 PAD, with PTFE being the most reliable one. PTFE also offers better water vapor resistance than 100 PAD, making it ideal for use in high humidity applications. The contact pins of the rectangular connector can be partially or fully pre-loaded which helps to improve electrical stability by providing a minimum PCB to receptacle contact force. This helps to improve the application\'s reliability and performance.

Conclusion

The STMM-115-01-G-D-SM Rectangular Connectors - Headers, Male Pins offer excellent electrical and mechanical performance in applications such as automotive, military and aerospace, as well as other harsh environment and high temperature applications. It is also compatible with through-hole and surf-mount technology and offers a low profile design making it ideal for tight spaces. The pins are protected by an over-molding which also helps to prevent damage to the pins, and the pre-loaded pins improve electrical stability and reduce contact fatigue. This makes it a highly reliable and efficient connector for a variety of applications.
