Terminal Blocks - Wire to Board

ESTT02120 Application Field and Working Principle

ESTT02120 terminal block is a kind of wire-to-board terminal block which provides a secure and reliable connection in a variety of electronic applications. Its excellent properties make it suitable for various applications such as industrial control, instrumentation, automotive, power supply, audio and other fields.

In general, ESTT02120 terminals are mainly composed of screw caps, contact blocks, seals, and inserts. The contact block is made of brass, copper, or nickel plated, ensuring good conductivity and contact reliability. The inserts provide a secure and reliable connection between the screws and the wires. The seals are designed for protection against dust, dirt, moisture, and other dangerous substances, ensuring a safe and fast connection.

The ESTT02120 terminal block has several distinct features that make it an ideal choice for a variety of applications. First of all, it provides a firmly secured connection by incorporating a threaded screw-type design. Secondly, it easily allows for wire sizes ranging from 28AWG to 10AWG, allowing for both thick and thin wires to be connected. Thirdly, installation is very simple – no special tools are needed to install, and all parts are preassembled.

In addition, the ESTT02120 terminal block is UL 94V-0 flame-resistance rated, ensuring excellent fire resistance and heat resistance up to 130°C, so it is ideal for applications where safety is a primary concern. Furthermore, this terminal block offers a superior current rating of 30 amps when using a 10AWG wire, and up to 40 amps in closed series connections.

The working principle of an ESTT02120 terminal block is quite simple: two wires are inserted into the terminal block, one into an input hole and one into an output hole. When the two wires are inserted, the positive and negative terminals (represented by two different contact blocks) meet, forming a connection. The contact blocks are made of a durable conductive material, ensuring a secure and reliable connection with minimal resistance.

Now, consider a scenario when an external device is connected to the terminal block. First, the wires from the device are connected to the terminal block’s input and output ports. Then, the positive and negative terminals (woodscrews) are tightened to firmly secure the connection. Any external voltage or current can then be passed through the terminal block for further work.

In conclusion, the ESTT02120 terminal block is a reliable and versatile electric connection solution. It is designed to form a secure connection between two wires for numerous electronic applications, and its flame-resistant rating makes it perfect for safety-sensitive applications. It also offers a superior current rating of up to 40 amps, ensuring a stable and reliable connection.
