HARTING ICC 20: Scalable, industrial circular connectors excelling in harsh environments


At HANNOVER MESSE 2025, HARTING presents additions to its ICC circular connector series size 20, featuring hybrid inserts and single-pole power connectors up to 400 A/600V.
HARTING ICC 20: Scalable, industrial circular connectors excelling in harsh environments

The HARTING ICC 20 4/3 ("4Slash3") represents an attractive solution for the supply and control of drives in robotics and automation, for example, handling power up to 40A in combination with signal contacts. The circular connector features the proven Han® C and Han D® contacts. Four power contacts, three signal contacts (up to 10A/250V) and one PE contact are accommodated in the insulator.

HARTING has expanded the ICC 20 series to include the Single Pole so that users can also transmit significantly higher power for their machines and devices. A single connector transmits up to 400A/600V, making it suitable for energy-intensive applications such as robot arms for heavy load handling or welding robots. Other application areas include mobile machinery and energy network infrastructure scenarios.

Moreover, all of the series housings offer a high degree of protection against the ingress of dust and water (IP67/IP69), making them ideal for deployment in harsh industrial environments. The housings reliably shield electromagnetic fields (EMC), thereby ensuring the signal integrity of the system.

The number of potential applications for the ICC 20 design is also multiplied by the integration of insulating bodies, which were previously reserved for theHan® 3A format. A multitude of especially efficient solutions for power, signal and data transmission are possible here – from simple Han® C, Han D® or Han® E monoblocks through to USB, RJ45 and other data interfaces. The size 3 A insulators also provide various connection technologies, such as the new push-in quick connection technology.

The prototype is currently available as ICC 20 with Single Pair Ethernet (SPE) and power transmission. Thanks to this HARTING solution, users can, for example, set up their cobots or robots for the future. The connector provides the basic power supply for the devices in an extremely compact installation space.

Benefits HARTING ICC 20:


  • High scalability due to the integration of Han® 3 A inserts (approximately 50 in total)

  • Durability thanks to robust design, vibration resistance and high IP67/69 protection ratings

  • Space savings of up to 20 % for individual interfaces

  • Up to 50 % higher output up to > 400A in the same installation space

  • Convenient installation and touch-safe contacts
