A-TB381-VM18

Terminal Blocks - Headers, Plugs and Sockets

A-TB381-VM18 is a compact terminal block with two rows for eight contacts on each row. Available in solderable versions, it can be easily mounted on a circuit board, or on freestanding terminal blocks with a threaded conduit. Its small size and robust design make it ideal for pulse and power distribution applications on PCBs in commercial and industrial control cabinets.

Application of A-TB381-VM18

A-TB381-VM18 is suitable for use as a connection point in industrial control boards, brake controls, home automation systems, sensor and controllers, and non-isolated, low-current low-voltage power components. It is typically used in applications where frequent rewiring is required, such as in power-efficient lighting systems. It is also used with automotive electronics, such as for power distribution and airbag safety mechanisms.

Working Principle of A-TB381-VM18

The A-TB381-VM18 is a simple plug and socket type terminal block consisting of a plastic housing, two rows of eight contacts, and two conductive pieces. When both rows of plugs are connected, an electrical circuit is created that allows current to flow between two separate points. In this way, voltage, current, and/or data can be transferred between two different points in a system. The plugs themselves can be easily removed and replaced, eliminating the need for complex wiring.

The two rows of plug contacts are edge-mounted on both sides of the terminal block, meaning that they can be easily connected with other components and wiring. The contacts are not soldered, but instead, screwed into the terminals. The choice of rated voltage and amperage is determined by the power requirements of the application.

Advantages of A-TB381-VM18

The A-TB381-VM18 has several advantages over more traditional wiring methods. It takes up much less space—at only 43 mm in length, it is much smaller than average terminal blocks. It is also easier to install, since it does not require soldering; the plugs can easily be removed and replaced without any extra effort. Furthermore, the edge-mounted design means it can be connected to other components and wiring without the need for additional mechanisms. This makes it ideal for applications that require frequent rewiring.

A-TB381-VM18 is also highly reliable, as it is designed to withstand a wide range of temperatures and vibration levels. This makes it suitable for industrial and extreme environmental applications. Finally, its small size and lightweight design make it ideal for applications in tight spaces and confined enclosures, such as those found in aircraft, satellites, or medical instrumentation.
