Han-Modular® - The market standard for modular connectors

With the Han Modular® series, you can optimally design connectors to supply machinery and equipment. This is made possible by combining individual modules for different transmission media – signals, data, power and compressed air – in standard-sized industrial connector housings.

Han Modular® offers easy-to-handle, highly flexible solutions with a small footprint and versatile functionality.

Han-Modular®: Endless combination possibilities

Han-Modular®: Unendliche Kombinationsmöglichkeiten
  • Integration of multiple connectors into a single unit

More information on Han-Modular®

PE module does away with special cables for power connectors

HARTING has extended the Han Modular® series with the introduction of a module for the pluggable connection of large PE cross-sections (10-35 mm²). The hinged frame of the Han Modular® series already features two integrated PE connections for the 0.5-10mm² cross-section range. Cross-sections of 10-35 mm² can now be realized using the new pluggable PE module. Special cables with reduced PE are no longer necessary. The PE module is simply mounted in the articulated frame, creating a secure, electrically conductive connection from the PE contact to the hinged frame and the housing. The PE protective earth connection is pre-leading and complies with standard IEC 61984.

LC Module for optical data transmission in the connector

The LC module enables users to leverage the advantages of transmission via fibre optic cable (FOC) for industrial connectors. FOC offer tremendous advantages in the transmission of sensitive data in industrial environments. It ensures interference-free transmission and displays no EMC issues, which is the case with copper-based data transmission. As a result, siting FOC infrastructure side-by-side with a power supply poses no problems in Han Modular® connectors. The high contact density of the LC module reduces the space required for fibre optic transmission. The LC module’s contacts are suitable for 50-62.5/125 micron multimode fibres as well as for single mode fibres. Typical applications for the LC module include data transmission in machinery and plant facilities.

Han Modular® for high mating cycles

Industrial facilities increasingly feature modular designs. More and more mobile equipment is being used in manufacturing, and swap-outs are being done more frequently and as quickly as possible. This also means that more connectors are required which are designed for a high number of mating cycles. The HARTING Han Modular® “High Mating Cycles” (HMC) hinged frame allows the integration of contacts designed for especially high mating cycles (10,000 insertions/removals) in inserts from the proven Han Modular® series. Use of the Han Modular® HMC hinged frame means Han® Modular modules can be integrated into a HMC housing – and are consequently equipped for over 10,000 mating cycles. The HMC hinged frame differs from conventional hinged frames particularly with regard to the PE contact. The contact is specially coated in the HMC hinged frame and is attached to the latter using a special process.

Modular connector for Ethernet networks

Networking and digitisation of manufacturing processes has meant an increase in the proportion of Ethernet components at the field level. To meet this trend, HARTING developed the Han Modular® Switch US4. The US4 enables components such as high-resolution cameras used for quality assurance to be e.g. integrated into the network of a production facility with little effort. The Ethernet Switch US4 is suitable for industrial applications and supports Ethernet (10 Mbit/s), Fast Ethernet (100 Mbit/s) and Gigabit Ethernet (1000 Mbit/s). Up to 4 devices can be connected via RJ45 ports. The US4 Switch is Plug&Play compatible, and integrated LEDs provide quick and easy power and network diagnostics. HARTING’s strategy towards smarter connectors goes further: an ID module provides memory space for the connector. Other solutions emerging on the horizon are integrated sensors and wireless modules in the modular connector.

Compressed air transmission in the connector

The Han® Pneumatic Module enables prepared compressed air to be transmitted via connectors, which is required for e.g. drives. The blue colouring of the pneumatic module makes it stand out from electrical modules. Depending on requirements, the male and female contacts can be used for various pneumatic hose diameters (∅ = 1.6 to 6mm). The module can also be combined with all other modules in the Han Modular® series. This means that in addition to electric power and electrical signals, fibre optic signals and gaseous media can also be transmitted in pluggable mode. The module is available in variants with two (for hose ∅ = 6 mm) or three plug slots (for hoses with ∅ = 1.6 to 4mm). The female contacts are available with or without shut-off function. In the shut-off variant a spring-loaded valve closes over an O-ring when the connector is opened. This prevents compressed air from escaping. When plugged in, the male contact presses against the valve and keeps the contact open

Han® – The standard since 1950

In the 1950s, the young engineer Wilhelm Harting recognised the need to make heavy connectors available for industrial applications, much as they had been used in military technology. Harting conceived the idea for a rectangular connector intended to be both robust and easy to handle. Working from these principles, he developed the HARTING Norm connector, or “Han®” for short.
