The Han® 1A: compact, robust and versatile

HARTING has been producing robust industrial connectors for over 70 years. From the very beginning, the focus has always been on developing products which are easy to handle, durable and suitable for a range of uses. Another important consideration is an ethos of continuous innovation, which gives users reliable solutions even as markets and industries evolve.

With the Han® 1A, HARTING has recognised and responded to industry demands for smaller interfaces to power engineering equipment. It requires up to 30% less installation space than the Han® 3A and provides users with all the benefits of a modern network.

Built from lightweight, durable polyamide plastic, the Han® 1A employs a system of modular inserts, making it extremely versatile. For power, it can transmit a maximum of 16 amps and 400 volts. Modules for Cat. 5 or Cat. 6A are available for data transmission and up to 12 D-Sub contacts can be used for signal interfaces. A shielded version is also available for areas which are susceptible to interference.


Only two components are required to quickly assemble an IP20 solution, while additional housing elements or single wire seals can easily extend the degree of protection to IP65, making it suitable for use outdoors. Accessories such as fasteners for wall mounting and colour coding pins to help identify different lines and reduce cabling errors are also available.

What’s more, as the entire Han® 1A connector system is based on just a few components, material supply is greatly simplified as a plug-in connection consists of a maximum of twelve different contacts. This gives you the flexibility to easily create simple and efficient interfaces for applications in mechanical engineering, automation, robotics, transportation, traffic engineering and the energy sector.

In mechanical engineering, it provides an efficient solution for connecting tools and smaller machine modules such as heating and cooling units, fans, control terminals, lighting systems, drives and vibration conveyors.

As it complies with standard EN 45545-2 for fire protection on railway vehicles, the Han® 1A is also ideal for use on door systems and ramps, door openers, push buttons, lighting systems and screens.
