Rectangular Connectors - Headers, Receptacles, Female Sockets

The ESQ-126-69-S-D-LL is a type of rectangular connector, which is categorized as headers, receptacles, and female sockets.

These connectors are used in electronic wire and cable assemblies to provide electricalinterconnection between circuit boards as well as between them and other components in machines,monitor platforms, and other equipment. They may also be used for the direct con­nection of logs, circuits,and other systems.

Application Field

These rectangular connectors are suitable for use in almost any type of electronic assembly. Theyare mainly used in construction and industrial sectors, as well as in audio-visual equipment,computers, surveillance systems, and motor vehicles. They are also used in power tools and deviceswhere space is limited, such as keyboards, appliances, and diagnostic equipment. These connectorsare designed to connect and switch electrical circuits and support various types of electronic components

Working Principle

This rectangular connector has a simple design that allows for an efficient functioning. It has a male header pins which inserts into a female socket which are then screwed in place. This ensures that the two parts are connected and hold securely. Theheader pins are punched into the housing to ensure a tight fit and provide maximum protection againstvibration, corrosion, and abrasion. The female socket has an integral screw for secure connection tothe wire or cable, while the male pins have a special groove to hold the wire and provide a mounterconnection. The connector also has a protective sleeve which helps protect it from environmentalconditions and prevents short-circuiting.

In order to ensure optimal performance and reliability, these connector pins and sockets need to bescreened and tested for electrical and mechanical properties before use. Mechanical tests includeinspecting the pin/socket engagement force, contact retention force, current carrying capacity, andinsulation resistance, while electrical tests involve testing for insulation resistance and contact resistance.

The ESQ-126-69-S-D-LL is an ideal solution for any rectangular connector application. It offers a robust,cost-effective method of connecting circuits securely and reliably for a variety of applications. Thanks toits high-reliability and flexibility, these connectors are a popular choice among industries andapplications, making them a great choice for any project or task.
