Terminal Blocks - Barrier Blocks

Barrier blocks are terminal blocks with the added feature on an insulated housing. The aim is to electrically “block” any wire from a certain terminal from making contact with any other terminals. Barrier blocks are ideal for applications which require wires coming into the same enclosure to be separated, and are especially effective in power supplies.

1546692-4 Application Field and Working Principle

The 1546692-4 is an ultra compact, daisy chain-able, electric interlocking terminal block. The angular, solid copper design of the mating pins help to provide an optimal contact for secure connections and allow for modular and compact designs. It is ideal for applications such as consumer, commercial, and military vehicles, LED lighting, home cameras, and medical devices.

This terminal block operates on the principle of electricity through contact between the pins and the insulator walls that create an electrical circuit. When the terminal block is connected to two external devices, a continuous current will flow through them and create a closed circuit. The interior surfaces, or “barrier blocks” of the terminal block are insulated and will prevent any current from flowing between the two sides. It also serves to protect any other terminals from possible electrical shocks.

The 1546692-4 is the perfect solution for applications which demand high reliability and a compact form factor. This terminal block is UL recognized – meaning that it is tested and approved to the industry’s highest standards and features a terminal spacing of 3.5 mm for a more confined mounting. It is designed to handle up to 16A and is equipped with mounting holes at the end for a more secure fit.

The 1546692-4 is an ideal solution for applications where the highest quality and reliability are required. With its insulated “barrier block” housing, this terminal block will ensure secure connections while helping to protect other terminals and components.
