Terminal Blocks - Headers, Plugs and Sockets

Terminal blocks, also known as headers, plugs and sockets, are devices used in a variety of electrical engineering applications. In their simplest form, they are used as connectors and are ideal for providing power and signal connections between components or circuits. They provide a reliable, secure connection for cables, and offer good electrical insulation and performance.The A-TB381-TT04 terminal block is a specialized version of this type of device. It is an isolated terminal block, designed for low-voltage, low-current applications. It is rated to a maximum current of 5 Amps and can handle voltages of up to 250 VDC. The terminal block features a 2-pole design, and each individual pole is capable of accepting two 18 AWG wires. It is designed for use in a range of industrial, automotive, medical, and consumer electronic applications.The A-TB381-TT04 terminal block is designed to provide a secure and reliable connection between two components or circuits. The electrical contact between the two terminals is ensured by the use of two screws, which are tightened using a screwdriver. This creates secure electrical contact between the two wires, providing a reliable connection.The terminal block also features a built-in LED indicator. This LED serves two purposes. Firstly, it indicates whether the electrical conduction between the two terminals has been established or not. If the LED is illuminated, it means that the connection is working. Secondly, the LED also serves as an indicator of the operating current. If the current is excessive, the LED will turn on, indicating an overload or short circuit. This is a useful feature, as it helps to protect the circuit from damage caused by excessive current.Another key feature of the A-TB381-TT04 terminal block is its vibration-resistant construction. This helps prevent any electrical contact failure due to vibration or shock. The terminal block is also designed to be dust- and water-resistant, ensuring a long service life.In conclusion, the A-TB381-TT04 is an ideal choice for low-voltage, low-current applications. It provides a secure and reliable connection between two components or circuits, and features a useful LED indicator to help protect it from damage caused by electrical overloads. It is also robustly constructed, ensuring a long service life in a range of industrial, automotive, medical, and consumer electronic applications.
