The new Han-Eco connectors provide enhanced functionality for the industry standard Han B compared to their metal-case counterparts. Innovations include e.g. the option of rear mounting when assembling a switch cabinet: pre-assembled inserts no longer need to be inserted from the outside into a bulkhead-mounted housing on the control cabinet wall.
During assembly, the ends of the wiring harnesses can be snapped into the mounting housing from the inside of the switch cabinet – rearward. This option simplifies assembly and thus saves time and costs. Switch cabinet units and cable harnesses can be pre-assembled separately. A better division of labour is possible and, if necessary, processes can even be outsourced. In addition to monoblocks for Han B, the Han-Modular range can also be used in plug-compatible fashion in the new Han-Eco. The hinged frame allows the modules to be integrated into the plastic housing. As a result, this considerably increases the application possibilities for plastic housings in manufacturing. The new plastic connectors are plug-compatible with the standard metallic Han B housings.
Compatibility with existing interfaces in environments using the Han B standard is thus fully guaranteed. Subject to cost and quality requirements, designers can take advantage of all the benefits of plastic and/or metal. The high-performance plastic of the Han-Eco B is as robust as that of all other Han-Eco components. The usual advantages are retained: plastic connectors are not only easy to install, they are also resistant to corrosion and offer flexible assembly options.
They are fire resistant to UL94 V0 – which means they are also suitable for use in railway scenarios – and weigh only about half as much as a connector in a die-cast aluminium housing.
In addition to monoblocks for Han B, the Han-Modular range can also be used in plug-compatible fashion.
