Application Field and Working Principle of SQT-140-03-S-D
SQT-140-03-S-D belongs to the rectangular connectors - headers, receptacles, and female sockets. It is a 3-row, 40-position series, with dual `L\' support, lead-free compliant, 0.35mm (high density) pitch.
Application Field
SQT-140-03-S-D connectors are commonly used in various network appliances and protocol converters. Specifically, this connector can be used in products such as Wireless Routers, Power Line Communication (PLC) adaptors, Network Interface Cards (NIC), embedded communication modules, Internet of Things (IoT) devices, security cameras, etc. Moreover, the headers, receptacles, and female sockets also enable the device to be connected to other devices or external equipment.
Working Principle
The working principle of the connectors is simple. The connector has two parts - the header and the receptacle. The header is installed in the circuit board and the receptacle is connected to the module or the part to be connected externally. When the two parts of the connector come into contact, the electric signals are routed along the designated wires, and the connection is then established.
The SQT-140-03-S-D connectors have dual \'L\' support which means that the receptacle is held securely on the header by two \'L\' shaped brackets. This provides better stability and improves the connection between the two parts, leading to faster and more reliable data transfer. Additionally, the connectors are lead-free compliant, meaning they are composed of materials that do not contain harmful substances such as lead. This makes them safer and more environment-friendly.
In conclusion, the SQT-140-03-S-D connectors are widely used in various network appliances and protocol converters, as they provide a reliable connection between the device and its external components. They are a cost-effective and easy to install solution.
