Introduction
FSH-120-04-LM-DH-SL is a type of rectangular connector named headers, male pins. This type of connector is used in many applications, and it is important to understand their application field and working principle prior to using them. This article will discuss the application field and working principle of the FSH-120-04-LM-DH-SL.Application Field
FSH-120-04-LM-DH-SL are commonly used in a variety of applications, such as computers, printers, industrial automation, and automotive electronics. The FSH-120-04-LM-DH-SL rectangular connector finds its use in the cases that require extra protection and long-lasting security for the connections. In addition, they are also used for communication and power management applications.Working Principle
The FSH-120-04-LM-DH-SL rectangular connector is composed of two parts: the header and the male pin. The two parts are connected using a single slot, which is typically rectangular in shape. The slot is designed to accommodate the male pin, and a groove is present in the header for it to lock into. The edges of the slot are designed with bevels and notches, which help secure the pin, providing it with extra protection and ensuring that the connection remains secure.The slot on the header and the male pin are both made from metal alloys or plastic, depending on the application. The metal alloy composition ensures maximum toughness and durability during operation, while the plastic composition limits electrical shock. The size of the male pin varies depending on the application, but it determines the maximum power and current transfer capabilities of the FSH-120-04-LM-DH-SL connector.The FSH-120-04-LM-DH-SL also has two distinct contact surfaces; a gold chromium plating on top and a plated tin on the bottom. The gold chromium plating ensures a good contact between the connector and its counterpart, while the plated tin plating provides additional protection against corrosion and oxidation.Conclusion
FSH-120-04-LM-DH-SL are a type of rectangular connector that are commonly used in many applications. They are composed of two parts, the header and the male pin, and are secured using a single slot. The slot is designed with bevels and notches to ensure the connection stays secure. The contact surfaces are gold chromium plating and plated tin, ensuring a good contact between the connector and its counterpart. Understanding the application field and working principle of the FSH-120-04-LM-DH-SL is important prior to using them.
