Terminal Blocks - Headers, Plugs and Sockets

The ELFH17290 from Hirschmann is a simple 5-pole pluggable terminal block designed specifically for industrial and commercial applications, where fast and reliable connections are essential. The ELFH17290 is also compliant with IEC/EN 60 60947-5-1 and UL 1059 requirements.

Application

The ELFH17290 is suitable for quick, error-proof wiring in a wide variety of industrial and commercial applications, from automation and control systems to electrical and mechanical systems of all types. It is also used in medical and consumer electronics products, as well as gas and water distribution systems.

The connector’s 5 poles, which are configured in a straight line, enable it to handle current pressures of up to 12 amps. This makes the ELFH17290 ideal for powering well pumps, valve controllers and other equipment requiring a large amount of power.

Design Features

The ELFH17290 terminal block features two rows of five poles, allowing for easy isolation and quick connection. The terminals are housed within a strong, lightweight thermoplastic material that protects the terminals from both corrosion and mechanical damage. The block’s flexible design also allows for manipulation of the terminals in tight spaces, while its versatile mounting options enable it to be installed in the wall or panel.

The ELFH17290 is designed with an innovative twist-lock head that securely attaches wiring, even with significant movement or vibration. Its quick-plug system also facilitates fast connections and disconnections with a minimum amount of effort. The connector also features an integrated release mechanism that prevents accidental disconnections, as well as a thermal release device for additional safety.

Working Principle

The ELFH17290 terminal block utilizes a simple twist-lock principle. In order to connect, fully extend the connector wire into the plug and then twist the head of the plug clockwise until the terminal locks into place. The twisting motion causes internal contacts within the block to secure the wires. To disconnect, twist the head of the plug counterclockwise until the terminal is released. The connector can then be easily removed.

Conclusion

The ELFH17290 terminal block is an ideal choice for a wide variety of industrial and commercial applications. Its simple twist-lock mechanism, secure connections and versatile mounting options make it a reliable and cost-effective terminal block solution. By combining innovative design with safety features, the ELFH17290 is the perfect choice for any wiring project.
