RedDot Award for "HARTAL hidden contact".
The Hartal hidden contact was developed for a more pleasant user experience with our doors. The solutions available on the market so far do not fulfil this function sufficiently. For the control of the central locking system and the feedback of the locking position, the signals must be transmitted outside the door. In cooperation with our stakeholders, the current status was analyzed and desired improvements and changed marginal conditions were discussed. The following points were compiled: More economical production; improved safety with regard to failure and external influences; upgrading of the overall door system and detection of faults already in the assembly plant.
The new door contact integrates itself almost invisibly into the existing design of the internal hinge. Door variants with or without contacts retain their basic design and can hardly be distinguished from one another. The new design covers the contact pins much better, which leads to an enormous improvement in safety. Thanks to the Poka Yoka design, installation is easier.
The first serial parts were tested according to our high requirements. Even after an endurance test of 25000 cycles.
