At this year’s HANNOVER MESSE 2025, HARTING will be presenting the latest additions to its circular connector series ICC (Industrial Circular Connectors) in size 20. These include solutions with hybrid inserts enabling parallel transmission in several lifelines, for example data and power, as well as single-pole power connectors up to 400 A/600V. The application fields range from robotics and automation through to mobile machinery and energy grid infrastructure.
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 the Han® 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.
Summary: The HARTING ICC series stands for circular connectors performing a wide range of tasks – from the transmission of data and low voltages through to the supply of high-performance applications.
