18-161-R

Terminal blocks are a type of electrical connectors used to join electrical and electronic circuits. They are an essential component in electronics, providing electrical isolation and protection, as well as secure and easy wire termination. The 18-161-R is a termination block developed for use in industrial automation systems and other applications.

Unlike other terminal blocks, the 18-161-R comes with a switch which, when opened, shuts off power to the block. This feature is useful for when circuit breakers are not included in the design, as the opening of the switch will provide protection for the block and its components against power surges and other faults. The opening of the switch also helps to reduce the amount of contact over voltage across the block, offering additional protection for sensitive electronic components.

The 18-161-R also features a one-piece plastic body housing which is designed to withstand the constant vibrations and shock found in industrial environments. The block is made of durable polyamide-based material which will not corrode or crack even in the most extreme conditions, and its interlocked contacts provide dependable, long life connection between wires. The 18-161-R is designed to be compatible with standard sized wiring systems, making it easy to install into existing systems, and the use of industrial-grade aluminum alloy contacts ensures the block will have a long life even in the most demanding applications.

The 18-161-R is well-suited for a wide range of applications, including those in industrial automation and controlling, instrumentation, power transmission and distribution, instrumentation and communications. Its robust, sealed construction make it resistant to environmental shocks and vibration, and its one-piece body ensures it is easy to install, maintain, and repair.

The working principle of the 18-161-R terminal block is simple. When the switch is open, two sets of contacts are connected, allowing power to flow freely. When the switch is closed, current cannot flow, and the block and any connected components are then disconnected from the power supply. This ensures that no power surges or other faults can occur, as the switch can be quickly and easily opened to shut off power to the block.

In conclusion, the 18-161-R is an excellent choice for a wide range of applications in industrial automation and controlled instrumentation. With its robust construction, powerful switch, and simple working principle, it is a hard-wearing, reliable solution for any industrial application.
