Introduction

The SQT-140-01-LM-Q rectangular connector is a power-electronic connector that is widely used in various applications such as mobile phones, computers, and embedded systems. Rectangular connectors are a type of electromechanical device that is used to be securely connected to the printed circuit boards (PCB) of electronic components. Headers, receptacles, and female sockets make up the three types of rectangular connectors. The SQT-140-01-LM-Q rectangular connector is in the category of headers.

Application Field and Working Principle

The SQT-140-01-LM-Q rectangular connector is mainly used in automotive applications in order to connect sensors, transducers, relays and switching components to the vehicle\'s system. It is also used in many other electrical and electronic components including computers, mobile phones, and embedded systems.The SQT-140-01-LM-Q rectangular connector is composed of two main parts - the plug and the socket. The plug and socket are mated when the male and female pins of the connector are aligned and pushed together. This interaction creates a secure electrical connection between the two parts of the connector.The SQT-140-01-LM-Q rectangular connector is most commonly used in power electronic applications because it can efficiently and quickly power the connected components. The connector consists of over 140 pins, which are arranged in 2.54mm spacing. This allows for the quick and secure connection to a large number of external components.The connector also works to reduce noise interference. The contacts are securely screwed together, which creates a tight-fitting connection that prevents electrical interference. This is important for power electronics since electrical noise can interfere with the system’s power delivery and cause disruption or damage.The SQT-140-01-LM-Q rectangular connector also has an IP rating of IP 68. This means that it is resistant to water and dust ingress. This is useful in automotive and other outdoor applications, where the connector may be exposed to water or dust.

Conclusion

The SQT-140-01-LM-Q rectangular connector is a useful power-electronic connector that is used in a wide range of applications. It is designed to quickly and securely power connected components, while also reducing the risk of electrical interference. Its IP rating of IP 68 also makes it well suited for outdoor applications.
