The ESQT-105-03-M-S-375 connector from InspecTech is a rectangular connector header, receptacle, and female socket. Available in an astonishing array of sizes, material types, and plating, this connector offers a versatile solution for many different applications. When selecting the right one, it is important to know the application field and working principles of the connector to ensure that the quality of the connection is maintained.

The ESQT-105-03-M-S-375 is designed for commercial applications and is suitable for High Temperature operation up to +105 degrees Celsius. It is also available in several plating/finishing options, such as tin-plated, silver-plated, and gold-plated. This allows engineers to select a material that best suits their application.

This family of connectors is also rated for continuous temperature cyclic performance from -50°C to +105°C, and is UL94VO approved, making it a great choice for applications where connection integrity is of the utmost importance. Additionally, the connectors are IP67 rated, making them suitable for harsh, often wet, environments.

The core working principles of the ESQT-105-03-M-S-375 are based on the well-known crimp/screw locking mechanism. The terminal pins are inserted into the connector and the corresponding terminal contact is attached to the individual pin. To perform a reliable mechanical and electrical connection, the connector must first be crimped onto the terminal pin to secure it and then a corresponding screw is tightened onto the terminal contact. This locking mechanism creates a reliable electrical connection and keeps the pins tightly in place.

The crimp connection method has advantages over other methods, as it can be used with a wide range of terminal types and can provide a low contact resistance. This makes it ideal for lightweight and small format electronics applications, where reliability is a must.

The ESQT-105-03-M-S-375 is also designed with advanced vibration and shock resistance, making them excellent for use in applications, such as automotive and industrial, which are often subject to high levels of shock and vibration. The connectors are also RoHS compliant, making them suitable for use in a variety of commercial applications.

The ESQT-105-03-M-S-375 is a versatile, reliable, and cost-effective solution for a wide range of applications and is an excellent choice for engineers looking for a quality connector that won’t break the bank. The crimp connection allows for a robust, reliable, and low contact resistance connection, and the advanced internal construction offers vibration and shock resistance. This makes the connector ideal for numerous commercial and industrial applications where quality and reliability are key.
