Introduction to SQW-139-01-L-D

Types of Connectors

SQW-139-01-L-D is a type of rectangular connectors, also known as headers, receptacles, female sockets.

Application Field

SQW-139-01-L-D are primarily used in manufacturing and automated production, process control, pneumatics and hydraulics, and aerospace.

  • Manufacturing and Automated Production: Connectors like SQW-139-01-L-D are used in industrially automated systems, allowing for the quick and easy transfer of power, data, and control signals.
  • Process Control: Connectors like SQW-139-01-L-D can be used in process control systems, which require the transfer of high-frequency data or control signals over short distances.
  • Pneumatics and Hydraulics: In pneumatics and hydraulics, SQW-139-01-L-D are often used to transmit pressure, temperature, and other data related to the movement of fluids.
  • Aerospace: In aerospace, connectors like SQW-139-01-L-D are often used in avionics systems, where they are used to transfer signals such as acceleration, altitude, and temperature.

Working Principle

SQW-139-01-L-D connectors are based on the principle of a "contact" and a "socket". The "contact" is typically a metal pin or blade, and it is the part of the connector that makes the electrical connection. The "socket" is typically made of metal or plastic, and it is the part of the connector that houses the contacts.

When two connectors are mated, the contacts of one connector fit into the sockets of the other connector. This creates a direct connection between the two connectors, allowing for the quick and easy transfer of power, data, and control signals.

Conclusion

SQW-139-01-L-D is a type of rectangular connectors used in various industries. It is based on the principle of a "contact" and a "socket", and when two connectors are mated, they create a direct connection between them, allowing for the quick and easy transfer of power, data, and control signals.
