Rectangular Connectors - Headers, Receptacles, Female Sockets are a type of electronic parts that are a combination of a connector housing, contacts, and a terminal cover. The most commonly used rectangular connector is the ESQ-121-44-S-T-LL. This rectangular connecter is small and versatile and is commonly used in many applications including automotive, telecommunications, and medical.

The ESQ-121-44-S-T-LL rectangular connector consist of a thermoplastic-molded housing that has three identical groups of 44 contacts. Each contact is gold plated on the contact side while the mating side is tin plated. The contact pitch is 2.0mm and the insulation resistance offered by the connector is 2,000 MΩ. It supports current transfer up to 9A. The electrical rating is 250V AC / DC and the operating temperature range is -25°C - 85°C.

The ESQ-121-44-S-T-LL has a wide range of applications in the automotive, telecommunication, and medical industries. In the automotive industry, the connector can be used to connect the airbag warning lamp, electric power steering, and ABS systems. In the telecommunication industry, it can be used to connect electrical switches, optoelectronic devices, and systems for telecommunication equipment such as digital exchanges. In the medical industry, the connector is often used to integrate medical devices, such as pacemakers and monitoring systems.

The working principle of the ESQ-121-44-S-T-LL is relatively simple. When two units of the connector mate together, the contacts are actuated, enabling electrical current to flow from one connector to the other. The contacts are held firmly in the housing, and the electrical connection is secured by the terminal cover. As the connectors are mated, the terminal cover secures the connection, protecting it from external contamination and ensuring reliable connections.

In addition to providing reliable and secure electrical connections, the ESQ-121-44-S-T-LL is also designed with low insertion force and excellent mechanical stability. This ensures that the connectors are easy to use and can withstand vibration and shock. As the connectors are easy to install and use, they are ideal for applications where frequent connection and disconnection is required.

The ESQ-121-44-S-T-LL is a reliable and versatile rectangular connector that can be used in a wide range of applications. Its durable construction and low insertion force make it a great choice for applications requiring quick and secure connections.
