QTH-120-05-L-D rectangular connectors fall into the arrays, edge type, mezzanine (board to board) category owing especially to their combination of features. These connectors are manufactured to assemble and bring together many categories of rigidity, contact compatibility and dust resistance. Arrays, edge type and connectors of mezzanine variety are components that do not require screws or soldering due to their special features and are thus modular and ideal for prototyping as they can be quickly taken apart and remounted. This is due to the way such connectors internally bridge or contact board traces, as well as provide sufficient grounding and shielding.

At its most basic, the QTH-120-05-L-D connectors are 2x6 array plug connectors which feature 0.050" (1.27mm) pitch, two rows, six contacts and a depth of 5.49mm (0.216”). This set of features as applied to the connector allows for various interconnect methods that make it compatible with most industry standards. Due to its size, there are two mated heights for two size options of 0.100” (2.54mm) and 0.118" (3.00mm). The QTH-120-05-L-D connectors also have an operating temperature that ranges from -55°C to 85°C.

The working principle of the QTH-120-05-L-D connectors is based on a combination of several technologies. On one hand, the use of standard headers along with contact pins lets the connectors to be used with most applications. This is in addition to the use of a polarized receptacle that ensures secure mating while maintaining suitable mating pressure. Meanwhile, the use of a molded-in guide rib ensures perfect alignment when mating the connectors. Dust caps are also provided for use in dusty and moist environments.

An important aspect of the working principle of the QTH-120-05-L-D connectors is impedance matching. This helps to ensure that the signal’s quality is not compromised when the connectors are in their mated state. Moreover, the use of shielding helps to protect the contacts from any potentially harmful electromagnetic interference (EMI). This is done by the shielding covers, which are mesh-like structures that can be applied over the contacts. The square corner style of the covers also offers effective strain relief.

In terms of application field, the QTH-120-05-L-D connectors are mainly used in the avionics and aerospace industries, although their utility extends further. In particular, they are used in applications that require great flexibility in terms of experimentation, prototyping and assembling. Additionally, they are ideal for applications that require compatibility between two components, whether it be a motherboard and a daughter board, or even for making prototypes.

It is clear to see why the QTH-120-05-L-D connectors fall under the arrays, edge type, mezzanine (board to board) category of connectors. Their combination of features makes them one of the most versatile and reliable connectors available, thus they are perfect for a variety of applications related to aerospace, avionics and experimentation.
