In the field of modern industrial automation and equipment manufacturing, connectors and cable systems are one of the core parts for the reliable operation of equipment, especially under heavy load conditions where stable transmission of power and signals is highly demanded. As a world-leading industrial connection solution provider, Germany's HARTING (Hao Ting) has gained wide application and recognition in high-intensity usage scenarios such as rail transit, machinery manufacturing, and energy equipment, thanks to its sturdy and durable rectangular connectors and matching cable products. HARTING industrial rectangular cable harness components belong to the Han® system, covering a wide range of specifications from basic power signal connections to complex heavy load communication combinations. They feature dust and water resistance (up to IP65/IP68), high current carrying capacity, and modular configuration, making them the preferred connection solutions for many industrial applications.

One, HARTING Industrial Rectangular Cables and Rectangular Connectors Features Analysis
Adaptation design for complex environments
HARTING's rectangular connectors and cable systems are manufactured using high-strength materials and precision engineering. The housing and sealing design fully meet the IEC standard IP65/IP67 protection level requirements, capable of adapting to harsh industrial environments such as dust, humidity, and vibration.
Modularization and flexible configuration
Han® series connectors support various sizes, pole numbers (such as 6, 10, 24, 48, etc.), and different locking and wiring methods. Users can configure them independently according to specific current, voltage, and space requirements to meet diverse industrial field connection needs.
Integrated power and signal cable matching
HARTING provides industrial cables such as Han® system power and signal cables that not only ensure stable power transmission but also enable integrated cabling when combined with signal communication cables, thereby enhancing the overall reliability of system connections.

Two, selection suggestions and compatibility alternative solutions reference
In the product selection stage, it is recommended to evaluate from the following dimensions:
1) Current/voltage level selection
Select the corresponding Han® series size based on actual load conditions. For example, smaller sizes are suitable for low current signal connections, while larger sizes are suitable for high current or multi-way combined connections.
2) Protection level and environmental adaptability
Is there a water, oil mist, or strong dust environment on site? It is recommended to choose connectors and cable components with high IP protection levels to enhance long-term operation reliability.
3) Connector compatibility and alternative solutions
Although HARTING is a leading global brand for industrial rectangular connectors, in actual projects, alternative solutions can also be considered based on supply cycle, cost, and localization considerations:
Domestic brand compatible versions: There are already some rectangular interface compatible products provided by brands such as WEIDMÜLLER, LAPP, etc. on the market, which can be used as alternatives to the HARTING standard.
Customized harness and modularization solutions: Customized harness design is carried out according to actual applications and interface standards, while using domestically produced high-performance connectors can also achieve a balance between system performance and supply chain localization.
Function replacement components: For certain scenarios that do not require high protection levels, industrial standard connectors such as M12, RJ45 can be used to replace some Han® overload interfaces to reduce overall costs and enhance the domestic supply chain flexibility of the whole machine.
Combining system costs, supply cycle, and on-site maintenance convenience, reasonably planning the domestic substitution and compatibility scheme can not only optimize the supply chain but also enhance the comprehensive competitiveness of the project.

HARTING industrial rectangular cables and connectors have established an industry benchmark as pioneers in connection solutions for heavy-duty environments. Choosing the right connection system not only affects the stable operation of equipment but also significantly improves system maintenance efficiency and life cycle performance. We have extensive experience in assisting customers with selection and solution optimization, and can provide professional advice based on different application scenarios.
We have been focusing on the research and development of domestic alternatives for HARTING industrial connectors and cables, as well as their market application development. If you are interested in domestic alternatives for HARTING products, are in need of procurement, or wish to explore more cost-effective and reliable domestic compatibility solutions, please contact: Manager Zhang.
