Terminals and Terminal Blocks

What are Terminals and Terminal blocks?

SNK Terminals are a type of industrial control terminal that is used in industrial automation, process control, and other applications. These terminals are designed to provide a secure and reliable connection between the user and the machine. They are typically used to control machinery, monitor production processes, and manage data. SNK Terminals are available in a wide range of sizes and configurations, allowing them to be used for many different types of applications.

Modular terminals are components that can be used to connect two or more devices together in a network. They are typically used to connect computers, servers, routers, switches, and other network devices. Modular terminals are often referred to as RJ-45 connectors because they use an 8-pin RJ-45 connector.

A terminal block is a type of electrical connector used to connect two or more wires together. It typically consists of a metal or plastic housing containing multiple terminals, which are the points at which the wires are connected. Terminal blocks are commonly used in industrial and commercial applications to provide a secure connection between electrical circuits.
