Introduction

The ESQT-116-02-L-D-440 is a rectangular connector, belonging to the family of headers, receptacles, and female sockets. Typically used in conjunction with a mating connector, or an extension device, the ESQT is a versatile electrical interconnect designed with synchronous and bidirectional signals in mind. In this article, we will explore the application fields and working principles of the ESQT connector.

Application Fields

The ESQT connector is suitable for a variety of applications. It is well-suited for low to medium-density power and signal applications, such as printed circuit boards, backplanes, and cable assemblies. It can be used in any environment, such as in general purpose digital systems, industrial process control, or consumer electronics. Additionally, its 16-contact configuration makes it well-suited for higher-density systems.The ESQT connector boasts a robust design, featuring a versatile range of terminations such as AmpTy® Copy and flange mount. Accepting wire sizes of 36-20 AWG, the connector has multiple environmental protection features due to its application range of -40 Deg C to +100 Deg C. It is an optimal solution for small form factor interface applications, as well as static applications in harsh environments.

Working Principles

The ESQT connector is a snap together connector that requires no special tools for assembly. It works by pushing the connector over the mating part and latching it into place. This ensures a secure connection which also achieves the EMI/RFI performance requirements. The connector contacts are corrosion resistant and durable, ensuring a long-term electrical connection. The ESQT connector is also designed for shielding applications, which reduce system EMI/RFI noise issues. The contacts are shielded from the environment and the contact pins have plated gold over nickel which reduces the risk of arcing and mechanical contamination. Furthermore, the ESQT connector complies with the Bellcore 310-020 standard for environmental tests such as shock and vibration.

Conclusion

The ESQT-116-02-L-D-440 connector is an excellent and versatile choice of header, receptacle, and female socket. With its robust design, versatile range of terminations, and ability to work in harsh environments, it is an optimal solution for a variety of applications and is an ideal choice for small form factor interface systems. Its snap-together contacts provide a secure electrical connection, as well as ensuring EMI/RFI performance requirements are consistently met.
