Han® Rear-Fit: Quick installation of interfaces inside the switch cabinet

Han® industrial connectors are particularly suitable for environments that require the simplest possible installation yet place high demands on component robustness. Until now, installing control cabinet interfaces first required cables to be routed through a cutout in the outer panel. Assembling the inserts then took place outside the control cabinet.

This is different with the new Han® solutions: the prefabricated inserts can be snapped directly into the bulkhead housing from inside the control cabinet. This results in time and cost advantages.

The contact inserts are mounted in a plastic mounting frame that snaps securely into the rear-fit mounted housing made of aluminum and, if necessary, the frame is just as easy to disassemble. The attachment of the PE connection to the metal housing is structurally ensured. To achieve an IP65/66 degree of protection to and to protect against UV radiation and ozone emissions, a flange rubber seal runs the whole way inside the rear-fit mounted housing.

The rear-fit option makes the assembly of prefabricated units more efficient. Connections for control cabinets and machine modules can largely be pre-assembled separately. This results in cost advantages.

The new Han® rear-mount connectors are compatible with previous connector generations. All contact inserts and modules from the Han® line can be used without restriction in the new rear-fit mounted housings. "Effectively immediately, manufacturers of robotics and automation technology now have a new, economically interesting alternative in the Han® portfolio," says Gero Degner, Technical Application Manager Installation Technology Han® at HARTING Electric.
