How to Configure a HARTING Han-Modular Control Cabinet Connection

Short answer: Han-Modular is a build-a-connector system. Choose the modules your circuit needs, seat them in a hinged frame, then close that frame inside a standard Han hood or housing. Size the frame to the module count first, match each module to what it carries (power, signal, data or air), and let the hood set the IP rating.

Three layers, one connection

A Han-Modular control cabinet connection is assembled from three layers, and each layer answers a different question. The module is the functional unit: it decides what the connection carries and at what current, voltage or data rate. The hinged frame is the carrier: it decides how many modules fit and holds the two leading protective-earth contacts. The hood or housing is the shell: it decides the protection class and how the cable enters. Because the layers are chosen separately, the same frame can carry completely different modules for different machines.

This is why HARTING calls the series modular. The official Selection Guide Han-Modular (version 8.1) lists more than 100 modules covering power, signal, data and compressed air, all of which seat into the same patented hinged frame inside the well-established Han hoods and housings. You are not limited to a fixed pin layout the way you are with a Han A, Han B or Han E insert.

Size the hinged frame to the module count

The frame is the first decision because it sets the ceiling on everything else. HARTING's hinged frames come in the same B-size steps as the Han shells, and the module count follows the size:

Frame sizeModulesOrder example (Hinged Frame Plus)Typical cabinet role
6B209 14 006 0361Two media types: one power + one signal or data
10B309 14 010 0361Power + signal + one data or air line
16B409 14 016 0361Power + signal + data + spare slot
24B609 14 024 0361Full mixed interface: power, signal, data, air

A Han L32B shell steps up to 8 modules when a single interface must carry a lot. The rule of thumb is to leave one spare slot: a 16B frame for a four-module job gives you room for the sensor or fieldbus line the next retrofit will add, and spare capacity costs far less than re-terminating a cabinet later.

The frame also carries the protective-earth system: two leading PE contacts with 0.5 to 2.5 mm² on the signal side and 4 to 10 mm² on the power side, so earthing is handled by the frame itself rather than by a dedicated module.

Choose modules by what the cabinet carries

After the frame, pick modules. The useful way to think is by transmission medium, because that is how the catalogue is organised and how the ratings differ:

Module familyWhat it carriesTypical rating (from the selection guide)Use it when
Power modulesMotor, drive and heater currentHan 40 A, 70 A, 100 A, 200 A, 300 A axial or crimp modulesThe circuit feeds real load current, not just logic
Signal modulesControl and sensor circuitsHan E 16 A; Han DD 10 A / 250 V; High Density 4 A / 32 VYou need many low-current contacts in one frame
Data modulesEthernet, fieldbus, USB, coaxRJ45 cat. 6A 10 Gbit/s; M12 X-coded 10 Gbit/s; Gigabit cat. 8.2 40 Gbit/s; Quintax coax up to 500 MHzThe interface carries a network or bus, not just signals
Pneumatic modulesCompressed airUp to 10 bar; tube 3, 4, 6, 8 or 10 mmThe machine needs air alongside the electrical connection

The power and signal families also include crimp versions and field-assembly versions, and the Domino modules let you combine small cubes (for example an EE cube at 16 A / 400 V next to a DD cube at 10 A / 250 V) so a single frame slot does more than one job. If a module changes, you replace just that module, not the whole insert.

Read the module ratings before you commit

Two numbers decide whether a module is safe in your cabinet, and they are easy to misread from a family name. First, current per contact: a "Han E" module is rated 16 A, but a High Density module is 4 A at 32 V, so a 24 V sensor circuit is fine while a heater circuit is not. Second, limiting temperature: the system maximum is -40 to +125 °C, but pneumatic, optical and data modules sit lower, so a hot cabinet wall is a real constraint for a data module even when the power module next to it is fine.

On the mechanical side, the standard frame is rated for more than 500 mating cycles, and the HMC version for more than 10,000 — the difference that matters when a test rig or tool changer is unplugged daily. Housings and frames meet DIN EN 61984 and DIN EN 60664-1, and the module housings are UL 94 V0 rated polycarbonate with zinc die-cast frames and copper-alloy contacts.

Three cabinet configurations, worked

Here is how the same three-layer logic plays out in practice:

Cabinet needFrame + modulesWhy it works
Motor drive on a machine tool16B frame: one Han 100 A power module, one Han E signal module, one RJ45 data modulePower, control and Ethernet share one plug, so the drive drops in and out as one unit
Sensor island with compressed air10B frame: one Han E signal module, one pneumatic module, one spareAir and electrical signals ride the same interface, and the spare slot covers the next sensor
Test rig unplugged every day10B HMC frame (10,000+ cycles): two signal modules + one data moduleThe HMC frame survives daily mating where the standard 500-cycle frame would wear out

The hood sets the IP rating, not the module

A module does not carry an IP class by itself — the protection comes from the shell around the frame. Metal hoods and housings in the Han B, Han EMV, Han M and Han HMC ranges are IP65, and the Han HPR range reaches IP68 for rail and outdoor duty. Inside the cabinet, Han-Snap and grip-panel frames are IP20, which is normally enough because the cabinet already provides the enclosure. Choose the hood by environment, and do not forget the cable glands: an IP65 hood with an unsealed cable entry is not IP65.

Mistakes that delay commissioning

Three errors show up again and again. Buying the frame too small — a 6B frame holds two modules, and adding a data line later means a new frame and a new panel cut-out. Mixing a 16 A power assumption into a 4 A signal module — the family name looks close, but the contact rating does not. Forgetting the air line — if the machine uses pneumatics, a pneumatic module turns three connectors into one, but only if you plan for it before the frame is sized.

FAQ

Q1. What is HARTING Han-Modular and how does it work?

Han-Modular is HARTING's build-a-connector system. Instead of one fixed insert, you pick individual modules (power, signal, data, pneumatic and more) and seat them in a hinged frame, which then closes inside a standard Han hood or housing. The official selection guide lists more than 100 modules, so one plug can carry several transmission media at once.

Q2. How many modules fit in a Han-Modular hinged frame?

The frame size sets the count: a 6B frame takes 2 modules, 10B takes 3, 16B takes 4 and 24B takes 6. A Han L32B shell can carry 8 modules. Pick the frame by how many media types and circuits the connection must carry, and leave one spare slot if the design may grow.

Q3. Can I mix power, signal and data in one Han-Modular connector?

Yes, that is the point of the system. One 24B frame can hold a high-current power module next to a signal module and an RJ45 or M12 data module. Two rules to respect: keep sensitive data modules away from power and use shielded modules where the data sheet requires it, and note that pneumatic, optical and data modules have a lower limiting temperature than the -40 to +125 °C system maximum.

Q4. What IP rating does a Han-Modular connection achieve?

The rating comes from the hood or housing, not the module. Metal hoods and housings in the Han B, Han EMV, Han M and Han HMC ranges are IP65, and the Han HPR range reaches IP68. Inside the cabinet, Han-Snap and grip-panel frames are IP20, which is normally enough because the cabinet shell already protects them.

Q5. How do I order the correct Han-Modular configuration?

List every medium the connection carries (power, signal, data, air), count the circuits, then choose the frame size, the modules, and finally the hood or housing and cable glands that set the IP class. Send that list with the complete part numbers and our team will verify the combination before you buy.
