HARTING connectors - 4 proven connectivity solutions for industry and automation
1. HARTING DIN 41612 connectors
This series remains a firm favourite thanks to its massive variety of configuration options. Originally engineered in Germany, this classic board-to-board standard quickly became a global benchmark, with the original DIN 41612 specification eventually transitioning into modern international standards like IEC 60603-2 and EN 60603-2.
Often called Eurocard connectors, these robust, pitched signal interfaces feature a timeless layout so deeply embedded in industrial architecture that they are practically guaranteed to remain in active service for at least another 50 years.
Classification of HARTING DIN 41612 connectors:
- By pitch spacing - 2,54 mm, 5 mm, 5,08 mm, 7,62 mm
- By row configuration - single, double or triple-row options
- By mounting style - PCB, cable-to-board, and panel mounting
- By orientation - right-angled or straight
Typical applications:
You can find HARTING DIN 41612 connectors across a wide spectrum of industrial hardware, and they are especially popular in rack enclosures.
- Industrial automation equipment
- Railway transport
- Defence industry
- Testing systems
- Data and control centres
2. HARTING Han series rectangular industrial connectors
Patented by HARTING in 1956, the Han series is the definitive standard for heavy-duty industrial cabling and the product line that originally built HARTING's global reputation. This rugged rectangular footprint remains an industry staple, serving as the foundation for a constantly expanding ecosystem of modern variations. Despite numerous third-party market copies, genuine Han rectangular industrial connectors are still highly sought after by designers who refuse to compromise on build quality, long-term field reliability and balanced total cost of ownership.
The series is incredibly versatile, letting you combine signals, high-current power and even pneumatics into a single interface. Depending on your housing selection, you get ingress protection of IP65, IP67, up to IP69K, keeping contacts perfectly sealed against aggressive environments and high-pressure washdowns.
Key architectural traits of the HAN rectangular series:
- Heavy-duty metallic or plastic hoods and housings
- Highly secure locking levers and latching mechanisms
- High-grade resilient gaskets
- A modular approach that allows you to configure a custom connector layout tailored precisely to your application
- Ability to mix high-density signal lines and high-current power contacts
Typical applications:
Han series HARTING rectangular industrial connectors withstand extreme conditions, even with harsh and frequent use in:
- Railway and truck transport
- Construction machinery and machine tools
- Industrial automation
- Medical devices
3. HARTING insulation displacement connectors (IDC)
If you need to terminate high-pin-count ribbon cables quickly, IDC connectors are your best bet. The technology was originally developed in mid-20th-century America to mass-terminate telecom wiring, and its core advantage remains the same today. The contact slices directly through the cable insulation to establish a reliable, gas-tight cold weld with the conductor. No wire stripping required.
HARTING's IDC connectors cover standard pitches like 2,54 mm, 2,0 mm and 1,27 mm. Thanks to precise stamping and high-grade materials, these systems remain popular as they mate predictably and hold up beautifully in the field without unexpected contact issues.
Typical applications:
General-purpose use for connecting multiple signals between printed circuit boards or between a printed circuit board (IDC connector) and another connector (IDC version of a D-Sub connector) on the panel of an electronic device.
4. HARTING D-SUB connectors
Many engineers still call D-SUBs "Cannon" connectors, nodding back to ITT Cannon's original 1952 layout that once dominated the back of every PC. While the footprint is classic, HARTING modernized it by focusing on rugged build quality and sensible pricing.
If you have ever dealt with loose pins or cracked shells on cheap, generic D-SUBs, switching to HARTING D-SUB connectors is a quick, painless way to boost your system's field reliability.
New in HARTING D-SUB connectors: Practical Push-Pull connection
Instead of forcing technicians to fiddle with traditional jackscrews in tight spaces, HARTING has introduced a quick-mating Push-Pull mechanism. It provides an incredibly fast, toolless connection that handles heavy vibration with ease, making it a natural fit even for tough railway applications.
Typical applications:
- Industrial automation
- Transport
- Robotics
- Test and measurement equipment
