Terminal Blocks – Headers, Plugs and Sockets play an important role in most industries and applications mainly because they open the opportunity to easily connect and disconnect two pieces of electrical equipment. One of the most used products of this type is the ELFK17210E from Erni Electronics. In this article, we will analyze its application field and working principle.

Application Field

The ELFK17210E from Erni Electronics is a transversal connector composed by pairs of plug-in terminals which provides versatility and ease of use due to its “plug and unplug” feature. It has a wide operating temperature range, up to +125°C, and an IP rating of IP20 which makes it suitable for most application fields. Thus, this connector is used in industrial and automotive industries, such as product works and industrial control systems, HVAC, household appliances and motor starter systems. It works specially well in high power and high voltage applications due to its large testing current capacity, up to 24A.

Working Principle

The terminal blocks of this model are composed of pair of plug-in terminals that can be snapped together, providing the appropriate physical environment for the connection and transmission of power and signals. This system consists of a frictional lock between the terminal block and the mating header, ensuring a secure connection and avoiding vibration. Due to its polarization functions, the connection of the plug-in terminals is simple and fast.

The ELFK17210E also offers operational safety and reliability, mainly due to the even distribution of the force of the frictional lock, which reduces concentrations of stress, thus ensuring a secure connection of the conductor in the terminal point. Moreover, it can be quickly locked or unlocked with the use of standard tools, such as flat head or Phillips screwdrivers.

Conclusion

The ELFK17210E from Erni Electronics is one of the most used products in the Terminal Blocks – Headers, Plugs and Sockets category. Its main features are a wide operating temperature range, a large testing current capacity and an IP rating of IP20, making it suitable for most industry applications. Furthermore, it provides operational safety and reliability due to the even distribution of the force of the frictional lock and can be quickly locked or unlocked with the use of standard tools.
