Pressure Wave Switches

The pressure wave system stands out thanks to its high level of response sensitivity, which enables it to protect 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. Pressure-wave switch systems are practically failsafe and maintenance-free, plus they offer a particularly favourable price-performance ratio.
