The Han® 1A industry connector

To date, the Han 3A has been the smallest rectangular connector in the Harting portfolio. Now it’s been shown that it can be even smaller. The new Han® 1A connector series requires up to 30 percent less installation space than the Han® 3A and boasts impressive lightness, modular design, high flexibility and an extensive range of accessories.

Industrial machinery is becoming smaller and smaller at the same time as modularisation continues to advance. Drives and sensors are increasingly distributed -- and interfaces also need to keep up with this trend. Harting's answer to this is the Han® 1A. The small, light and flexible rectangular connector is particularly suitable for connecting decentralised loads. The Han® 1A enables modular design and supports miniaturisation, and the new industrial connector requires 30 percent less installation space than the smallest rectangular connector in the Harting portfolio, the Han® 3A.

Compact, robust and versatile

Apart from contacts, locking clips and seals, the components of the Han® 1A are made of high-performance polyamide – a plastic which optimally balances robustness and flexibility. As a result, the series is not only characterised by its small space requirement, but also by its low overall weight. This is especially true when compared to connectors in metal housings.

The series consists of eight different pairs of contact inserts for the transmission of data, signals and power. Integrated locking and external metal brackets are available for locking. The series even offers shielded variants for the transmission of data and signals that require no more installation space than their unshielded counterparts and enable simple, process-reliable shield transfer.

The Han® 1A can also be used as a machine interface as well as for cable-to-cable connections. Accessories include single-wire seals that can be used to easily increase the degree of protection. Additionally, individual wires can be branched off, hence wiring can be routed from a connector in different directions, and complex wiring harness structures can be set up.

The modularity of the Han® 1A offers flexibility in terms of machine design. Depending on requirements, use is possible both in a protected area, e.g. as an interface in control cabinets or machines, as well as in harsh industrial environments. Numerous configurations ensure the reliable transmission of data (speed 10 Gbit/s), signals (up to 12 contacts) and/or power (up to 16 A/400 V).

With the Han® 1A, HARTING presents a tailor-made, yet flexible solution

Few components, numerous advantages

The versatility of the connector is based on one special feature: the insulating body and housing of the Han® 1A form a unit that can be firmly connected using a clip or bracket. With the help of single wire sealing mats and housing elements, the user can gradually convert the system from an IP20 to an IP65 solution – and thus tailor it to a specific application.

Because a whole range of different interfaces can be developed from just a few basic elements, the Han 1A® offers several advantages for users. On the one hand, the cost of stocking is reduced since little storage space is required. On the other hand, the different interchangeable contact inserts give the user the flexibility to be able to react quickly to specific customer requirements.

Tool-less assembly saves time

A special feature of the Han® 1A is that the insulating body and accessories can be installed without tools. This speeds up the commissioning of machines and production systems, which in turn saves time and costs. The series also maintains a balance between cost-effectiveness and the greatest possible flexibility when it comes to connection technology. There are screw connections for quick and easy field assembly, but also crimp contacts for the assembly of large quantities of interfaces.

The connector’s areas of application include mechanical engineering, robotics and automation, energy generation and distribution, and rail vehicle construction. The Han® 1A enables the efficient connection of tools and modules, of heating and cooling units, fans, control terminals, lighting and vibration conveyors -- while being both robust and resistant to shocks and vibrations, which reduces the risk of machine failures.

Diverse application options

A classic application for the Han® 1A is conveyor systems. These systems are becoming ever smaller, which means that interfaces must adapt to them. Current applications still feature connectors that are almost the same size as the connected motor. The Han® 1A offers a tailor-made and at the same time flexible alternative: transitions, switches, dosing systems and vibration conveyors can be supplied and connected easily and inexpensively using handy interfaces.

The same applies to robotics. Large quantities are needed here, especially in the pick-and-place segment. Electrical loads are becoming lower and lower and drive components are getting lighter. To meet this trend, interfaces also need to transmit less power. The Han® 1A meets this requirement with its power range up to 16 A and compact format.

Harting’s “new little one” is also suitable for the inexpensive power connection of motors and for configuring data and signal interfaces, e.g. for machine controls and sensors.
