The Snap-in Piezo Button Permanent Open is a robust control element for automatic door systems, particularly suitable for activating the permanent open operating function.

In conjunction with an appropriately configured door control system, the button can be used to fully open an automatic sliding door and hold it in the open position. This function is suitable, for example, for situations with increased pedestrian or material traffic, where repeated automatic opening and closing of the door should be avoided.

Piezo technology enables reliable operation with a very short switching travel. Due to its sealed operating surface, the button is particularly suitable for areas with high demands on cleaning, hygiene, and mechanical resilience.
 

Intended Use

The snap-in piezo button serves as a control element for the permanent open function of automatic door and sliding door systems.

Typical applications include:

• Activation of the permanent open function
• Increased pedestrian traffic
• Patient and bed transport
• Material and equipment transport
• Operating rooms and functional areas
• Examination and treatment rooms
• Hospital and clinic corridors
• Laboratory and research areas
• Cleanroom and hygiene areas
• Automatic door systems in healthcare environments

The actual triggered function and the type of reset depend on the connected door control system and its configuration.
