Terminal Blocks - Barrier Blocks

A21930507 is a type of terminal block, more precisely a barrier block. As its name implies, a barrier block is a form of terminal block, but specifically designed with internal physical barriers to shield wires from other elements that are integrated to the block.

Barrier blocks come in a variety of forms, however, the A21930507 is perhaps the most popular, due to its sleek design, compact size, and versatile application possibilities. The A21930507 is designed for single line connection or mini three-line connection. It has five poles that are used to wire up simple DC connections, such as motor control, actuator control, or smaller sensor connection.

Generally, A21930507 barrier blocks are used as part of a larger circuit by connecting several such blocks together to kind of a simple network. This has the advantage of keeping all the wires neatly organized and making it easy to trace elements when diagnosing faults. It also eliminates the need to connect multiple wires into a traditional screw type terminal block as required in many control systems.

Working Principle

At the heart of the A21930507 are spring-loaded socket contacts. This makes the make the connection very reliable and repeatable each time you insert a male terminal. Since it is a barrier style block, it also has physical barriers between the different sets of contacts. This physically separates and prevents any form of external crosstalk or interference.

The pins on the A21930507 are designed for minimal resistance and the entire block is rated up to 12A @ 600V, depending on the cable/wire being used. The contact spring in the socket is compliant and reduces the risk of over-tightening during installation, thus reducing the risk of misalignment. Additionally, built-in test points on the block make it easy to diagnose any issues.

Application Field

A21930507 terminal blocks are used in a wide variety of industries, such as motors, motion control, lighting, HVAC, HMI, automation, and process control. They can also be used for PCB development, making prototyping faster and easier.

The modern design of the A21930507 makes it suitable for feed-through, breaker mount, and fast-connection style installation. In each style, the user may either fully insert the pins or half insert them, giving the user the flexibility to choose the most appropriate style for their application.

This terminal block is also exceptionally lightweight, making it easier to transport or manipulate. This, alongside its compact size and simple but effective design, makes it a popular choice for many applications and systems integrators, making it one of the most popular barrier blocks on the market.
