An efficient connection technology is the basis of every production technology. It guarantees functionality and value added. Harting connectors, housings and inserts from the Stecker Express product range cover a huge range of possible applications
Heavy industrial connectors from the Harting Han® series have been the global standard for a long time with their international approvals. They stand for an easy, flexible, quick and durable contact in a robust industrial environment. Various housings, inserts, contacts, connection technologies or locking systems can be combined with one another. You can obtain all the series of Harting Han® connectors from Stecker Express, including the best-known A, 3A and B.
Harting sizes from 3A to 48B
A safe, robust solution for all common requirements

Harting subdivides its housings into narrow models (Han A) and wide models (Han B). The Han A sizes are Han 3A, Han 10A, Han 16A and Han 32A. The Han B sizes are Han 6B, Han 10B, Han 16B, Han 24B, Han 32B bis Han 48B.
With regard to the housing designs of the Harting Han® industrial connector, a distinction is made between bulkhead-mounted housings, surface-mounted housings, screw-mounted housings and cable-to-cable housings as the lower part of the housing and hoods as the upper part of the housing. The upper parts of the housing are available as hoods with a high or low construction or angled, with a straight or side cable outlet.
The lower parts of the housing are available in three versions: As a bulkhead-mounted housing with or without a protection cover made of plastic or metal. As a surface-mounted housing with a low or high construction, with or without a protection cover (made of metal or plastic) and with 1 or 2 cable outlets. As a cable-to-cable housing with a low or high construction, the Harting Han® connector serves as a flying connection. Depending on their size, we offer Harting Han® housings with a number of threaded outlets and various Han-Easy Lock® locking systems.

New product: Harting Han-Modular® Domino System
The Harting Han-Modular® Domino System is the next stage of modular connectors. It is compatible with the various components of the Han-Modular® series, the market standard for modular industrial connectors. Therefore, the Domino modules can be easily integrated into existing systems; existing mounting frames, housings or connector modules can still be used and supplemented. Han-Modular® Domino System Just as a domino has two separate fields, a domino module is composed of two blocks, so-called cubes. Each module requires a cube with a small tab and a cube with a large tab. The cubes can be flexibly assembled using a gearing as required. A Han-Modular® Domino module enables the transmission of power, signals, data or compressed air, whereby pin and socket contacts can also be combined in a domino module.
Harting Han DominoHarting inserts and contacts
Inserts for Harting industrial connectors in a variety of series, sizes and connection technologies.

Harting Han Inserts
Inserts for Harting industrial connectors are available in a variety of series, sizes and connection technologies. Combining them with the appropriate contacts, the corresponding accessories and tools gives rise to a large number of possible applications. Depending on the number of pins, the space requirements, the tool insert and the conductor cross-section, a variety of connection technologies are available: The axial screw connection is a tool-free connection technology. There is also screw connection, crimp connection, Han-Quick Lock®, cage-clamp connection and double cage-clamp connection. In the case of a crimp connection, the contact must be ordered separately.
Harting Han contacts
The right contacts for Harting inserts, depending on the application. The contacts that are required in the Harting inserts are decided depending on the type of application. With respect to pin and socket contacts, you can choose between D crimp contacts, E crimp contacts, C crimp contacts, D-Sub contacts, E relay contacts, coaxial contacts and fibre optic cable contacts, with connection cross sections from 0.09 mm² to 70 mm². The decisive factor in the contacts is their materials: most of them are copper alloys with coatings made of gold or silver.

In railway applications, the Han® industrial connectors are used as connectors. The Han-Eco® connectors guarantee a safe data and signal transmission. An interface connector, on the other hand, handles all the necessary lifelines, such as data, signals and power, and reliably serves as an input and output path for a device’s information. In current measurement technology, current sensors promise exact measurement results, make a contact-free measurement of the currents possible and can also be used efficiently in power electronics. The product group of magnetic systems particularly handles customer-specific electromagnetic actuators for use in industrial series. In the area of checkout & vending machines, Harting’s flexible sales systems are the perfect solution for any application. Whether the customer is looking for vending machines, self-checkout systems or cash desks, security or the fulfilment of hygiene standards. With PCB connectors or the appropriate sockets, miniaturisation provides relevant solutions for connection technology in a variety of sizes. In system cabling too, the corresponding products provide a safe connection, whether in the form of individual data cables or system cabling. The robust data cables, cable systems and connectors are used wherever there is a harsh environment. Harting also provides various products for an optimal result in terms of the efficient development and expansion of industrial Ethernet networks. A fast and sustainable connection with a high quality is achieved with the tools such as crimping pliers or crimping machines and other comprehensive accessories. Highly developed charging equipment for electromobility, specifically for electric and plug-in hybrid vehicles, can be found in the Harting Automotive product category.
The connection technology for transport technology ensures a safe transmission of signals, data and power. Standardised and customer-specific products such as electromechanical interfaces, components and cable assembly lend themselves to use for mechanical engineering, in order to guarantee a safe transmission of data, signals and power. In automation technology, a modular structure provides for effective handling throughout the manufacturing process of the automated systems – the connection technology is extremely robust, can be expanded in modules and is completely reliable. In energy distribution and storage, reliable energy management provides absolute safety when it comes to the transmission of signals, data and power. The robust connectors with a modular design are also installed extremely quickly. In the food and retail industry, where smooth functioning - whether in relation to the cash desk, the portal software or the appropriate shelf elements - is necessary in order to optimise the flow of customers, the comprehensive portfolio covers all the requirements. Consistent processes for the decentralised drive technology ensure smooth handling in logistics centres and dispatch warehouses. Harting provides more flexibility and customisation for medical technology in particular. With the help of miniaturisation, specific new products and appropriate series solutions are being developed here. In mechanical engineering for tool machines, on the other hand, compact or complex solutions are required, which provide for a perfect connection at adapted electromagnetic or optical interfaces. In this context, highly efficient solutions support the future trends in the robotics market. In wind energy, special connectors guarantee a reliable connection for power generation and data communication. The Automotive division provides effective systems for the mobility solution of the future. Efficient system cabling of a data centre guarantees a maximum availability of the systems at data centres. Whereas the connector systems in agricultural technology provide a high level of protection and robust and easy handling, the large portfolio of assembly systems and special machines is characterised by the integration of state-of-the-art solutions in the design, development and production of the custom-tailored machines.
