  1. Pressure Wave Switches Profiles and switches for automatic doors and gates Maintenance free, robust, tried-and-tested • Very fast closing • Pressure wave technology for a high standard of switching reliability • Straightforward and robust structure • Millions of units successfully in service bircher.com

  2. Pressure wave switches For automatic doors, gates and barriers Can be used wherever a reliable switching pulse is required The highly sensitive response of the pressure wave system means that it protects people and vehicles from almost all directions. The robustness and durability of the pressure wave switch make it an impressive opening sensor as well. Quick and reliable Even low pressure of 3 to 4 mbar is enough to guarantee the electric contact will switch. Pressure wave switch systems are well proven and maintenance free, as well as offering a particularly good cost-performance ratio.

  3. Functional principles A pressure wave generated by the sensor reaches the pressure wave switch. The membrane deflects and the electric contact switches. The electric contact remains switched for as long as the input pressure is above the response pressure. With the contact (K) and valve screw (V) the switch's sensitivity can be set individually. Reliable in every application Situation Bus door/Train door Situation Roller gate Situation Barrier Solution Safety: Pressure wave profile DWS Solution Safety: Pressure wave profile DWS Solution Safety: Pressure wave profile DWS Advantages The pressure wave profile is very sensitive and switches quickly It protects against crushing and shearing, when the door is closing Advantages The pressure wave profile is very sensitive and switches quickly Advantages The pressure wave profile is very sensitive and switches quickly 3

  4. Pressure wave sensor Pneumatic pressure wave profiles Safety with profile When a rubber profile gets an impact, the inside air volume is compressed pulsed and thereby generates a pressure wave. It passes through the connecting hose to the pressure wave switch, where it triggers a contact. Order possibilities of the edges and rubber profiles 1.
