Terminal Blocks - Barrier Blocks are key components for establishing electrical connections between electrical wires and equipment. A404104 is such a product, serving as a perfect connection solution in the automation, transportation, automotive and control systems, plus other application fields. In this article, we will delve into the A404104 application field, and explore its working principle.

A404104 Application Field

The terminal block A404104 is typical of Rema’s 4mm safety terminal blocks. Other similar products include the A404110, A400110, A40230D, A402CY, and A400CY. When it comes to application fields, A404104 terminal blocks can be used in the following scenarios:

• various automation systems, such as PLC systems, CNC systems, robots, and drives.
• industry data acquisition systems, including communication, control, and monitoring of signals.
• transportation systems: railway, aerospace, and automotive.
• integration of machines, such as welding, machine tools, assembly.
• inverter and configuration of equipment.

In addition, the terminal block A404104 is applicable to schools, research institutions, electronic laboratories, and studios, where multiple equipment exist and need to be interconnected. Whether for daily applications or large-scale operations, applications of the A404104 can greatly reduce the complexity of wiring and assembly. It also helps to reduce costs, as the terminal blocks are construction-friendly and flexible to rewiring.

A404104 Working Principle

As a barrier block type terminal block, the working principle of the A404104 is to use the clamping force of the screw to fix the connecting lines. It consists of a triple-row, metal-clad contact base, a screw-mountable plastic body, and a steel or copper screw. The metal-clad contact base, located at the bottom, is able to securely clamp on the two wires, while the plastic body offers a secure protection for the bare metal.

Equipped with a 4mm opening terminal block, the A404104 can easily split or join electrical systems. Due to its robust design, the terminal block can be used to join flat, round, solid, and multi-stranded wires. A notch along the body of the terminal block indicates a safe separating point, making it much easier to replace the wires or change connections as needed.

In addition, the terminal block includes a unique insulation separation area. It isolates the metal-clad contact base’s front and rear connections, providing a secured and highly reliable connection solution. Depending on the configuration, the A404104 terminal block can feature a grounding area, which offers protection from electric shock.

Conclusion

In conclusion, Rema’s A404104 terminal block occupies a place among its peers for its reliability and durability. It’s a low-cost solution with a wide range of applications sold globally. It’s suitable for integration in any industrial market, especially the one mentioned above. What’s more, usages of the terminal block are straightforward and easy. It connects with dual-entry, and clamping screws hold the wire on both sides. The operating temperature range is from -55˚C to +125˚C. With such features, the A404104 is becoming an increasingly popular choice in industrial electrical connections.
