RSM-120-02-L-S-K: application field and working principle

RSM-120-02-L-S-K is a rectangular connector belonging to the Headers, Receptacles, Female Sockets category. It is mainly used in the automation and signal transfer domains, and it is provided with a 2.54 mm pitch. It is mainly designed for the purpose of reliable connection between PCB boards.

Application Field

RSM-120-02-L-S-K is a highly reliable connection between two PCB boards, designed for both signal and power transfer in industrial and home automation electronics. It has a socket guide for easy mounting of internal wires. It is usually used in high temperature, harsh environment, military and aerospace applications due to its robust build.

Working Principle

RSM-120-02-L-S-K is based on the cantilever principle. It consists of two parts: the plug, the header and the socket. The plug has two or more rows of pins, each of them of 2.54 mm pitch, which are in contact with the complementary holes of the header. The socket is connected to a PCB board having holes so that the pins of the plug and socket fit in them respectively. When the plug is inserted in the socket, the pins of the plug fit in the holes of the header and the headers fit in the holes on the PCB board to complete the connection.

Advantages

RSM-120-02-L-S-K has several advantages: it is an economic solution compared to wire assembly; it is very easy to mount, and the installation is correct and fast; it is also extremely durable and reliable; it has low electrical resistance, and so it is an efficient way to transfer power or data; it is resistant to dust and water.

Drawbacks

Although RSM-120-02-L-S-K has many advantages, there are still some drawbacks, such as its low durability in high-temperature applications. Furthermore, the contact resistance decrease over time, and the corrosion might occur if exposed to moist conditions. It is also relatively expensive compared to other similar connectors, and it is not suitable for extremely high current applications.

Conclusion

RSM-120-02-L-S-K is a rectangular connector belonging to the Headers, Receptacles, Female Sockets category. It is mainly used in the automation and signal transfer domains, where it is used for reliable connection between PCB boards. It works based on the cantilever principle and is a very reliable solution, although it is relatively expensive and not suitable for extremely high current applications.
