HARTING Han-Modular®

We've done it again!  See the next level of modularity with Han-Modular® Domino series, which allows customization of individual modules. 

What are Han-Modular® Rectangular Connectors?

The Han-Modular® series allows the combination of multiple media types (power, signal, data, and more) into a single connection point using off the shelf connectors.  With over 100 modules and compatibility with Han hoods and housings, engineers can build a connector specific to their applications. 


Product Details

Han-Modular® is the original and globally leading series of modular rectangular connectors. A modular connector allows the combination of several different media types into a single connection point. Using off-the-shelf modules, engineers can create custom connector systems perfectly tailored to their need in a standard footprint.

Standardization in module sizes offers the highest degree flexibility as engineers can change modules as their design changes without changing the footprint of the connector and thus, their complete design. Placeholder modules also allow for future proofing. As our multi-media connectors combine multiple connection points into one, it offers substantial space saving benefits.

One of the most important things Han-Modular® now offers is the ability to connect to the Industrial Internet of Things (IIoT) at the component level, making in the first “smart” connector on the market.

What is Han-Modular® with Cory Jenkins

Benefits of Modular Connectors

  • Space Savings – Integration of multiple connectors into a single unit allow for significant reduction in space requirements
  • Low-maintenance – Using a pre-assembled, pre-tested connector assembly can reduce hard wiring and installation time
  • Flexibility – With the Han-Modular® series, users can assemble their ‘own’ connectors according to their own individual requirements. Essentially creating a “custom” connector using standard stocked modules
  • Future Proof – Placeholder modules give you the flexibility to future-proof your modular connector design

Hinged frame offers more installation advantages and cost savings

HARTING has complemented the well-known Han-Modular® building block system with the addition of the new “hinged frame plus”. Among others, the “plus” for the proven hinged frame comes in the form of an additional stainless steel spring that holds the frame together in the open and closed positions, as well as other details that have been optimized. Particular time and cost advantages result from the fact that assembling the connector modules is easier and more efficient.

Compressed air transmission in the modular connector

The Han® Pneumatic Module enables prepared compressed air to be transmitted via connectors, which is required for e.g. drives. The blue coloring 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, fiber 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-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.

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.

Modular connectors for Ethernet networks

Networking and digitization 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 modular 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.

HARTING Connectors Outperform Hardwiring

Hardwiring vs. Connectorization

When comparing ways to bring power, signal, or data into an application – there are two choices, permanently hardwiring connections or using a connector. When weighing the two options, there are several considerations. The first, and most important, is how frequently the application will be disconnected/reconnected. When hardwiring, each wire needs to be painstakingly removed and reconnected, resulting in substantial labor costs. If anything is miswired, it can take hours of troubleshooting.

Using a connector costs more upfront, but once made, it’s a plug-and-play solution is impossible to miswire and does not require skilled labor. For many, the long-term benefits of using connectors significantly outweigh hardwiring.

Smart Han® – The Gateway to the IIoT

The latest expansion of the modular series is the introduction of Smart Han® modules that allow connection to the Industrial Internet of Things (IIoT) at the connector level. HARTING combines expertise in reliable connectivity with future-forward technology – in the footprint of the well-established Han-Modular® insert.

HARTING’s Smart Han® approach is to develop solutions in conjunction with leading IIoT thought-leaders, as needs arise, with the goal of making them globally available.
