Rectangular connectors are essential components for various devices, products, and systems. As a reliable and robust interconnecting solution, they can be used in numerous industries and applications. The SQT-105-03-L-D-009 is a rectangular connector package that is used in a wide range of application fields.

Applications and Usage

SQT-105-03-L-D-009 connectors are ideal for many electronic applications. This type of connector is designed for particularly harsh environment applications, such as those found in vehicles, aerospace, communications, and defense. It also provides excellent performance for liquid-proof and waterproof devices, such as medical, industrial, and instrumentation equipment. Furthermore, these connectors are suitable for industrial automation and process control systems, and are well-suited for external interconnections, such as those with cable and compasses.

SQT-105-03-L-D-009 connectors are designed for particularly harsh environment applications, such as those found in vehicles, aerospace, communications, and defense. Additionally, they can also be used in outdoor applications, as they are very robust and resistant to extreme environmental conditions, such as UV radiation, moisture, dust, and vibration.

Moreover, these connectors are extremely reliable and have a long service life. They are also designed to be user-friendly, with simple installation processes and easy maintenance. Additionally, they are designed to provide the highest possible signal integrity and performance.

Design and Features

SQT-105-03-L-D-009 connectors are available in a variety of standard sizes, with pitch sizes ranging from 2.54 to 3.99mm. They are also available in both through-hole and surface mount designs. They are designed for robustness and durability, with a maximum current rating of 16A. They also feature a secure screw connection, with four tamper-proof clips to secure them firmly in place.

These connectors are designed for high reliability. For instance, they are held in place with an anti-rotation feature that prevents the device from rotating, thus ensuring maximum conductivity and longevity. Additionally, they are designed to reduce electromagnetic interference, as they have a low signal reflection and crosstalk.

SQT-105-03-L-D-009 connectors are equipped with a dust cover that protects the contacts from dirt and corrosion. They also feature a unique, vibration-resistant small-foot design that reduces the risk of the connection being loosened due to vibration. Additionally, they are designed for easy installation and have an intuitive locking system to ensure their secure fastening.

Working Principle

When an SQT-105-03-L-D-009 connector is connected, an electrical contact is made with four inner contacts and one outer contact when inserted into the mating machine. These inner contacts are typically made of precious metal, while the outer contact is made of brass. The inner contacts are then surrounded by typically square female terminals, or crimp rings, which act as a gasket to ensure a tight connection.

For the connection to work properly, it is essential that the female terminals and the contact pins are properly aligned. This alignment is achieved using the small electrical contacts, which are inset on the connector\'s body. The contact pins are designed to connect each contact of the connector, enabling it to achieve its desired electrical performance.

Once the connection is made, the signal is then transferred between the contacts via an electrical current generated by an alternating current. This current is then converted to a usable voltage by the devices connected to the connector.

Conclusion

The SQT-105-03-L-D-009 is a reliable and robust rectangular connector package that is used in a wide range of application fields. It is suitable for harsh environment applications, such as those found in vehicles, aerospace, communications, and defense. Additionally, they can also be used in outdoor applications, as they are very robust and resistant to extreme environmental conditions. They are designed for high reliability, with secure screw connections, and an anti-rotation feature that prevents the device from rotating. Additionally, they feature an intuitive locking system and a dust cover to protect the contact pins from dirt and corrosion. Finally, they have a low signal reflection and crosstalk, enabling optimal signal integrity and performance.
