179970-4: Application Field and Working Principle

The 179970-4 terminal is a quick crimp connection system in the branch of housings, boots and terminals from Phoenix Contact. It has various applications in the fields of automation, industrial controls, switchgear, buildings, and infrastructure. This terminal not only ensures a secure connection between a conductor and the mating conductor, it also provides effective protection against voltage peaks, overvoltages and EMC disturbances. It is highly reliable and has a long service life.

Working Principle

The 179970-4 terminal utilizes a clip-in quick-connect system. It consists of a dielectric insulation body, a contact insert, a mounting latch, and a retaining clip. The contact insert is inserted from the rear into the insulation body into which a conductor up to 4mm² in size is crimped. A latch is then pressed down to secure the conductor, and the contact insert is retained by a retaining clip. This system is easy to use with its easy-to-handle, vibration-resistant components, and is suitable for both reliable and secure connections.

Fields of Application

The 179970-4 terminal is mainly used in the field of automation with its reliability and long service life. It is suitable for use in industrial control circuits, switchgear and switchboards, building automation, robotics, LED lighting systems, and commercial machinery. The terminal is also popular in the fields of infrastructure, power distribution systems, HVAC systems, and renewable energies.

Additional Benefits

The 179970-4 terminal offers a number of important advantages. It is designed to be vibration-resistant, making it suitable for applications that are exposed to mechanical vibration. It is also able to withstand high voltage peaks and overvoltage situations, as well as EMC disturbances. The terminal is made of high quality materials that are resistant to UL 94V-0 flammability rating, as well as halogen-free and lead-free.

Conclusion

The 179970-4 terminal is a quick crimp connection system that is suitable for a wide range of applications. It utilizes clip-in technology for fast and reliable connections, and is vibration-resistant, making it suitable for use in applications that are exposed to mechanical vibration. It is also able to withstand high voltage peaks, overvoltage situations, and EMC disturbances.
