HARTING’s Han 1A: flexible power, signal or Ethernet connections in tight spaces

HARTING's compact, robust and economical connector desinged for controllers, small drives and control cabinets.

The Han® 1A offers a compact, robust and universally deployable rectangular connector system for transmission in all lifelines of Industry 4.0 (data, power, signals). Smaller and smaller drives are also requiring smaller and smaller interfaces, e.g. in engineering and robotics.

The new connector series reflects the trend with matching housings and inserts. The necessary shielding for the motor connection can also be achieved with Han® 1A plastic connectors.

  • Uses up to 30% less space compared to Han® 3A: Compact connector for power that can be installed in the field
  • Flexible in use: Transmits data, signals and power with up to twelve contacts
  • Highly versatile: Modular system of inserts and accessories suitable for a wide variety of applications (IP20/IP65)
  • Less time required for installation: Fast connection using Snap-in technology – no screws required
  • Minimum inventory needed: Clearly structured connector system based on a few basic components
  • Reduced costs: Affordable installation connectors

The Han® 1A can accommodate power (10A to 16A @ 400V), signal (0.5A / 48V to 4A / 250V) and Ethernet data (M12 Cat 5 D-Code or Cat 6A X-Code insert) connection solutions, minimising BOM requirements and allowing lower piece stock costs.  It also simplifies interface panel design through one standard panel cut-out. Snap-on colour coding clips allow part differentiation.

The inline free or cable to cable mounting frame mating allows the M12 Cat 5 D-Code or Cat 6A X-Code inserts to be mated without the optical alignment concerns of the normal M12 housing connectors.  Hence, they offer the benefit of easier handling in tight, difficult to access spaces. This can be particularly beneficial behind thin panels in applications such as train carriage cabling. 

The new standard for small, universal industrial connectors

Increased miniaturisation in the machine/facility construction sector is also occurring in harsher industrial environments. Compact and versatile – yet still robust – industrial connectors are in demand. 

For the first time, HARTING's Han® 1A offers a compact, affordable power connector, which can be used for controllers, small drives and control cabinets, and can also be installed in the field.

Space-saving industrial connectors for railway vehicles

In order to save energy and optimally use the installation space available, rail vehicle designers are looking for miniaturised solutions. Electrical interfaces can also contribute to the development by becoming smaller and more efficient.

With the Han® 1A, HARTING presents a new small as well as powerful interface that clearly undercuts the dimensions of the smallest rectangular industrial connector so far, the Han® 3A.


A global market leader in the manufacture of connectors and interconnection systems, Harting is renowned for its reliable connector solutions. HARTING’s products cover data processing, control and measurement applications within industrial machinery, food and beverage equipment, rail, automotive, energy distribution, wind power and robotics.
