K.A. Schmersal: Door Handle System DHS

Thanks to RGB technology, the DHS door handle can light up in seven colours, clearly and unmistakably signalling different machine statuses. The user can control these colours individually and assign them to the desired operating status. The door handle is also equipped with a push-button, the colour of which can also be individually defined by the user using the push-button caps supplied. The push button can be used for a reset function, for example.

For the manufacturer, the new DHS door handle system offers the advantage that no separate door handles, indicator lights or control devices need to be installed. This saves time during installation. The operator benefits from the fact that the machine status can be recognised at a glance and all the necessary operating functions are at hand. This is possible because a matching control panel labelled BDF40 has also been developed for the DHS door handle system.
The control panel with four control/display elements features a flat design that allows it to be easily integrated into the surrounding structure. It is available with or without an emergency stop function and can be seamlessly combined with the DHS door handle system via a connecting element.

In addition, the DHS door handle system can be combined with safety switchgear so that the system can also monitor the position of the safety gate in this combination. There are two options: The first is a safety sensor from the RSS260 series. In the F0 and F1 versions, the RSS260 takes over the tasks of a safety relay module. The advantage: There is no need to use a separate evaluation unit.

If dangerous run-on movements are to be expected or if the safety door is not to be opened for process protection reasons, the DHS system also offers a solution: the combination with the compact AZM40 electronic solenoid interlock.
