Terminal blocks, also known as headers, plugs, and sockets, are electrical connector components used to join wires or cables from two or more components in a system, or even to route extra power into the components. The 5439219 terminal block is a very versatile component for a wide variety of applications and is available in various sizes and shapes. This article will discuss the application field and working principle of the 5439219 terminal block.

Key Features of the 5439219 Terminal Block

The 5439219 terminal block features anodized aluminum construction with a black finish that resists corrosion and other environmental elements. It is available in 120mm, 90mm, and 70mm lengths as well as 4mm and 6mm hole sizes for easy strain relief. The terminal has insulation displacement contact (IDC) technology, which allows it to be connected without stripping wires. It also has a recessed wire entry slot that reduces wire breakage during installation and a built-in strain relief that prevents wire pull-out. The terminal also features a plastic bushing with a recessed button which allows for easy one-handed locking and unlocking. All these features make it an ideal choice for a wide variety of applications.

Applications of the 5439219 Terminal Block

The 5439219 terminal block can be used in a wide variety of applications, including industrial control cabinets, power systems, HVAC systems, and communication systems. It is especially well suited for applications where space is limited, as its slim design allows it to fit into even the most cramped of spaces. It can also be used in harsh environments due to its corrosion and weather-resistant construction. Additionally, it can be used in hazardous areas, as it has UL approval for use in Class 1 Divisions 1 and 2 areas.

Working Principle of the 5439219 Terminal Block

The 5439219 terminal block works by providing reliable electrical connection between two or more components in a system. It is composed of two plates (called clamp plates) which make electrical contact with the wires or cables. One of the plates has two large insulated holes for the cables, while the other plate has two smaller insulation holes for the cables. When the two plates are clamped together, the cables are securely held in place.

The connection is made by applying electrical current via a terminal block jumper(s), which when makes contact with the two plates, the current is conducted between the plates. To ensure a secure connection, the jumper should be positioned securely on both plates and should have sufficient contact pressure. For additional security, it is recommended to use a screw and cable tie to secure the jumper in place.

Conclusion

The 5439219 terminal block is an ideal component for a variety of applications, from industrial control cabinets to hazardous environments. Due to its durable construction, slim design, and ease of wiring, it is a reliable solution for a wide variety of situations. Its working principle is quite simple, consisting of clamp plates which securely hold cables in place when electrical current is passed through them via a terminal block jumper. With all these features, it is easy to see why the 5439219 terminal block is an ideal choice for a variety of applications.
