Terminal blocks, headers, plugs, and sockets are essential components in the field of electronics and production. The ELFR07250E applies to this segment by providing a number of features that are regularly needed for these applications. In this article, we’ll discuss the application field and working principle of the ELFR07250E.

Application Field

The ELFR07250E is a general purpose terminal block. It is designed for insulation displacement and has a 4mm pitch. This makes it perfectly suitable for a number of applications involving pairs, T/R (triple-redundancy) or four or more lines. It is particularly suitable for safety systems, data systems, automation, and audio applications.

It is ideally suited for use in tight spaces, such as cabinets, boxes, and device housings. It is also able to offer three and four-point connections to cables, as well as cable and cable connection thereto. This makes it a very versatile tool, able to be used in a wide variety of applications.

Design Benefits

The ELFR07250E has a number of benefits that make it a popular choice for installation work. It has a short design, which reduces its profile and helps save on space. This makes it particularly suitable in applications where the available space is at a premium. The snap-in design is also quick and easy to install.

The thermoplastic material provides excellent insulation from electric shock and vibration. Additionally, the insulation is designed to resist fire and corrosion. This makes it especially suitable for use in various hazardous environments. The seal also ensures that the contacts remain secure and reliable, while the special design of the retaining clip ensures that it remains in place regardless of the conditions it is exposed to. And lastly, the self-extinguishing design adds an extra layer of safety.

Working Principle

The basic working principle of the ELFR07250E is similar to that of other terminal blocks. It employs an insulation displacement contact (IDC), in which the metal contacts of the wire are pressed against the metal plates inside the terminal block. This creates a secure connection by effectively cutting away the insulation around the wires, which is why this type of terminal block is also known as an insulation displacement connection (IDC) terminal block.

The contacts provided by the ELFR07250E are manufactured from solid copper, hence they provide a secure and reliable connection. The secure locking mechanism ensures that the wire stays in place once it is pressed into the terminal block. The contact is plated with either silver or gold, which ensures that oxidation does not occur and that a good electrical connection is maintained.

The ELFR07250E offers excellent electrical performance in a variety of applications, making it an ideal choice. Its design and size make it suitable for use in tight spaces, while its mechanical strength and durability make it especially ideal for safety applications.
