Pneumatic airwave profiles for increased safety on public transport

-  The airwave system stands out thanks to its high level of response sensitivity, which ensures reliable protection for people and vehicles from practically all directions.

-   Due to their robustness and durability, these switches are also really impressive when used as opening sensors for automatic gates and vehicle doors on buses and trains.

-  Just a slight pressure of 3 to 4 mbar on the sensor is all that is needed to guarantee reliable switching. Airwave switch systems are practically failsafe and maintenance-free, plus they offer a particularly favorable price-performance ratio.

-  A pressure wave generated by pressing the sensing edge or sensor reaches the pressure wave switch. The membrane inside the switch deflects, causing the electric contact to close (open if switch is set to NC logic). The electric contact remains switched as long as the input pressure is above the response pressure threshold and before bleeding through the temperature compensation orifice.
