1 sensing the future Pressure Wave Switches & Sensors Switches, sensing edge assemblies, and additional components for automatic doors, gates, public transportation, and specialty applications Reliable, proven, maintenance free Activation from all angles with low force requirement Highly reliable, even in tough environments Simple and robust design with long mechanical lifetime Millions of switches successfully installed

2 Pressure Wave Switches & Sensors For automatic doors, public transportation & specialty applicationsations Universally Reliable The pressure wave system, due to its high sensitivity, is able to detect contact from people or vehicles approaching proaching from almost any angle and a low activation force reliably switches the electrical contact. Due to it's simple design, the system is extremely robust and reliable even under tough environmental conditions. Bircher Reglomat's pressure wave switch systems are a proven solution for a variety of applications. The systems are maintenance free and offer excellent cost-performance ratio. Pressure Wave Applications by Industry Aircraft Barrier gates Carwashes Clean rooms Cold storage doors Gates Hangar doors Industrial lifts handling Medical/veterinary equipment Public transit Spacecraft Stop switches Warehouse doors Whirlpools/hot tubs Vehicle doors 2

3 Technology Overview 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. A. Pressure setting screw B. Temperature compensating bleeding orifice A B B B B A Sensing Edge Applictions Automatic Overhead Door Airwave sensing edge assembly with switch protects people/ vehicles in the closing path of a door by reversing the door when contact is made with the edge. Quick reaction time is ideal for high-speed doors Activation from all angles with low force requirement Operating temperature range is suited for cold storage applications Bus/Train Door Airwave sensing edge assembly with switch protects people in the closing path of an entry or vestibule door. The door reverses when contact is made with the edge. Self-contained system does not require external power Highly sensitive to pressure from all directions for optimal safety Barrier Gate Airwave sensing edge assembly with switch protects people/ vehicles in the closing path of a barrier gate. The barrier gate reverses when contact is made with the edge. Soft rubber profile with low activation force requirement prevents injury to people or damage to vehicles Medical Equipment Airwave sensing edge assembly with switch can be used as an activation device to quickly and precisely position equipment. Resistant to cleaning chemicals and bodily fluids Increases patient/operator safety - no electrically conductive components used for device activation Route 2 3

4 Sensing Edge Assemblies Sensing edge assemblies, available in custom lengths and a variety of profile shapes, come fully assembled to conveniently suit your application. Bircher Reglomat's sensing edges are proudly assembled in the U.S.A. Assemblies are available with or without aluminum retainer. All standard sensing edge assemblies are supplied with 4" (101 mm) of PVC air hose unless otherwise specified. Additional length or neoprene hose material available by request. Switches sold separately. See back page for ordering information. Custom Sensing Edges From design to manufacturing, Bircher Reglomat can create a custom profile to suit your application-call for more details.
