The STMM-118-02-S-D-SM (or simply STMM for short) is a type of rectangular connector, commonly known as a header, and also as a male pin. These rectangular connectors are typically used in many different types of electrical and electronic systems, including industrial automation, laboratory equipment, networking hardware, telecommunications equipment, medical instruments, and automation control systems.

Description

The STMM is a small rectangular plastic housing that contains two rows of pins (21 pins in total), each separated by two plastic dividers on either side. The pins are metal and each one is numbered, from 1 to 21. The housing is often a grey or black plastic, but can also be coloured in order to denote certain functions (for example, blue might denote output pins). The male pins are mounted into the housing and the ends of the pins are exposed and can be inserted into compatible devices. The connector also includes two support lugs (or brackets) on the backside of the housing to help secure it into place.

Purpose and Application

The STMM connector is used in many different applications, especially in industrial automation equipment, laboratory equipment, networking hardware, telecommunications equipment, medical instruments, and automation control systems. It is most commonly used as an electrical interconnect device to pass signals between two devices. The STMM connector typically forms part of larger systems and is designed to interface between components on the same module or board.

The STMM is often used to directly or indirectly connect components to a microcontroller. For example, it can be used to connect an actuator or sensor to the processor, or to connect a digital display to the processor. In general, the STMM is an ideal solution for connecting devices in larger and more complex systems, as it provides a reliable and secure connection.

Working Principle

The working principle of the STMM connector is relatively simple. When two STMM connectors are mated, the pins on the male connector slide into the holes in the female connector. The two plastic dividers on either side ensure that the pins are aligned correctly. When the two connectors are mated, they form an electrical connection between two components.

The STMM connectors can be used in a variety of different ways depending on the application. For example, they can be used with jumper wires, in which the pins on the male connector are spread out and connected to other components using a wire; they can also be used with ribbon cables, in which several pins on the male connector are connected to the same cable.

Advantages

The STMM connector offers a number of advantages, the most notable of which is its reliability and robustness. The connectors provide a robust electrical connection which is highly resistant to vibration and shocks. This means that the connectors are ideal for use in harsh industrial environments where temperatures fluctuate and vibration may be present. Additionally, the connectors are relatively compact and do not require a lot of space, making them ideal for use in small electronic systems.

The STMM connector also has a low profile, meaning that it is not bulky and does not protrude too much from the components that it connects. This makes it ideal for use in tight areas, such as in embedded systems. Additionally, the connectors are easy to use and install, as all the necessary components are included in the package.

Disadvantages

Despite its advantages, the STMM connector does have some drawbacks. The connectors are limited in the amount of current that they can carry, typically no more than 5A. Additionally, the connectors are sensitive and require a bit of care when connecting and disconnecting them. Finally, the connectors can be prone to corrosion, as the pins are exposed to the environment.

Conclusion

The STMM-118-02-S-D-SM (or STMM) rectangular connector, commonly known as a header or male pin, is a type of connector used in many different applications. The connector has a small plastic housing which contains two rows of pins, each separated by two plastic dividers. The pins are numbered and can be used to connect two components in a reliable and secure manner. The connectors are reliable, robust, and compact, making them ideal for use in a variety of different applications. However, they have some drawbacks and can be prone to corrosion.
