ESQ-120-33-S-T-LL

Rectangular Connectors - Headers, Receptacles, Female Sockets

The ESQ-120-33-S-T-LL is a type of 2–row rectangular connectors used to connect printed circuit board (PCBs) components. The ESQ-120-33-S-T-LL connector has a 120 degree angle between the two rows and is designed to place components on the PCB in an offset manner. It is a thru-hole connector with 3 mm pitch and low-profile construction. This type of connector consists of a header and a receptacle and is suitable for high-density applications.

Application Field

The ESQ-120-33-S-T-LL connector is suitable for a wide range of applications. Electrical devices, including computers, office equipment, communications products, data storage, transport equipment, test and instrumentation equipment, and medical electronics, often use the ESQ-120-33-S-T-LL. Additionally, it is suitable for high-speed data transmission, audio, and video transmission which require reliable signal quality, such as automotive electronics.

Working Principle

The ESQ-120-33-S-T-LL board-to-board interconnect utilizes a header and a receptacle. The header is soldered onto the PCB and the receptacle is placed into the header. The header and receptacle provide a secure method of connecting the two components. The contact of the connector is a surface-mount pin that ensures a reliable electrical connection.

To connect two circuit boards with the header and receptacle, a spring contact is mounted in each of the four corners on the receptacle on the top and bottom of the board. The four contact points are then mated to the four contact pins on the header. The header and receptacle are secured with a clip. The clip takes up any additional space between the two components, eliminating any possibility of the contact becoming disconnected.

The rectangular shape of the connector helps to align the boards, and the 120 degree angle allows for multiple configurations. Its low-profile construction makes the ESQ-120-33-S-T-LL an ideal choice for dense applications. The connector is designed for greater flexibility and easier installation, and can be used in applications where a more rugged design is needed.

The ESQ-120-33-S-T-LL connector has good electrical conductivity, high temperature and humidity resistance, and excellent anti-vibration and corrosion resistance. It is also resistant to the effects of EMI/RFI, making it a good choice for use in medical electronics, communications, and automotive electronics.

The ESQ-120-33-S-T-LL connector is an excellent choice for high-performance, high-density applications. It is reliable and cost-effective, and offers a simple, efficient solution to board-to-board interconnect needs.
