As industrial equipment becomes more compact and power demands continue to increase, engineers are under growing pressure to maximise performance while minimising installation space. To address this challenge, HARTING has introduced the new Han® Size 4, a connector size designed to bridge the gap between the existing Han® 3 and Han® 6 ranges.
Closing the Gap Between Standard Sizes
The new Han® Size 4 is now available across the Han-Eco®, Han® B, and Han® HPR connector series, offering a compact solution that can reduce installation space by up to 40% compared to the next larger size. This makes it an attractive option for applications where panel space is limited but high current capacity remains essential.
Traditionally, engineers have had to choose between smaller connectors with limited current-carrying capacity and larger connectors that consume valuable space. Han® Size 4 helps overcome this compromise by providing a compact footprint while supporting demanding power requirements.
Designed for Higher Power Density
Many modern industrial systems require compact interfaces capable of handling increasing electrical loads. While a Han® 3A solution may be too small for certain applications, larger sizes can occupy more space than necessary. Han® Size 4 fills this gap, offering support for currents up to 70 A in selected configurations while maintaining a significantly reduced installation footprint.
The reduced connector size can also free up valuable space for supporting infrastructure such as cooling, ventilation, and additional system components, helping designers create more efficient equipment layouts.
Supporting Sustainability Goals
Beyond space savings, Han® Size 4 contributes to more sustainable machine and system design. The smaller housing size reduces material consumption, and the Han-Eco® version’s low-impedance silver-plated power contacts can help improve energy efficiency compared to some alternative connection technologies.
Ideal for Machinery, Robotics and Power Distribution
The new connector size has been developed with demanding industrial applications in mind. Typical uses include:
- Machinery and factory automation
- Robotics systems
- Drives and frequency converters
- Power distribution equipment
- Energy and transportation applications
Its compatibility with over 100 different Han-Modular® modules also provides excellent flexibility for designers looking to combine power, signal, data, and other connection types within a single interface.
Key Benefits of Han® Size 4
