Introduction
The QTH-120-07-L-D is constructed from high-quality, ruggedized materials, making it extremely durable and reliable in extreme environments. This rectangular connector meets the exacting standards of military and aerospace specs, which makes it ideal for use in applications such as smart trackers, tracking systems, high-altitude GPS systems, space navigation systems, avionics, and other military, aerospace and security electronics.

Application Field
The QTH-120-07-L-D is a commonly used rectangular connector which is designed for Array, Edge Type, and Mezzanine (Board to Board) applications. The connector provides reliable performance in extreme temperature environments, making it suitable for many different types of applications. The QTH-120-07-L-D is available in various sizes, with up to 10 contacts, making it ideal for use in aircraft and military applications. It also offers a low profile which ensures a compact footprint, making it suitable for a wide variety of applications. Additionally, the connector has a low level of insertion loss and a high level of crosstalk attenuation, meaning that it is suitable for a range of RF communication applications.

Style and Design
The QTH-120-07-L-D is a two-piece rectangular connector, typically consisting of a pin array and a sleeve, with the two separate pieces being mated together at the time of installation. They key feature of the QTH-120-07-L-D is its durability and reliability, as it has a housing and contact arms that are made from high-grade dielectric materials. The crimp type contact arms are designed to be durable, while also providing secure connections. The contact arms are fully insulated and feature strain relief, which helps reduce stress on the pins and prevents them from separating in the connector when put under strain. Additionally, the QTH-120-07-L-D is designed to ensure a low level of crosstalk attenuation.

Working Principle
The QTH-120-07-L-D is a two-piece rectangular connector which allows for simple and reliable assembly. The contact arms of the pin array and the sleeve are inserted through the mating plane of the socket, then clamped together with a mating nut. The contact arms are then compressed together and the connector is filled with an electrical or mechanical sealing compound for a secure connection. The contact arms can be tightened to a specific torque setting in order to ensure that the electrical contacts are seated properly. The QTH-120-07-L-D also has a built-in strain relief to prevent the contacts from separating and, when fully mated, provides a low-level of insertion loss. As such, the QTH-120-07-L-D is suitable for use in a wide range of applications, from military and aerospace to radio frequency and high-speed digital communication.

Conclusion
In conclusion, the QTH-120-07-L-D is a robust and reliable two-piece rectangular connector constructed from high-grade dielectric materials and designed for Array, Edge Type, and Mezzanine (Board to Board) applications. The connector provides a low profile, low level of insertion loss, and high level of crosstalk attenuation, making it suitable for a range of applications, such as aircraft and military devices, tracking systems, high-altitude GPS systems, space navigation systems, avionics, and more. Additionally, the built-in strain relief ensures that the contact arms remain together, even when the connector is subjected to strain. This ensures that the electrical connections between the two pieces remain secure and reliable in a variety of extreme temperature environments.
