Infrared vehicle separator ( infrared light curtain) is mainly consist of a receiver and an emitter, using the principle of counter shoot.The receiver and the emitter have the same quantity of LED and photoelectric cell, the LED in emitter and photoelectric cell in receiver is synchronous touched off, when the light is block off, the system makes the output.The receiver and emitter have built-in electrical heating glass as optical window, in the condition of bad weather (snowy, rainy, foggy), when the receiving beam becomes weak, the heating glass operates to heat automatically.In addition, the protected housing has temperature switch and humidity switch, the power of the heating glass is connecting in parallel to the light screen through these two switches, in order to detect the temperature and the humidity of the light screen in the outer environment, so that the heating glass of the light screen could be well protected. 

     G-TEK infrared light curtain have served China highway toll gate system for more than 15 years and gain high reputation with the high quanlity and performance.

• With Intelligent heating function，Defrost function starts automatically under severe weather to eliminate the block to light path from frost、snow、rain and fog；
• Aspheric surface optical lens totally eliminate spherical aberration、aberration and stray light；
• Build-in self-diagnostic function，detection output function and alarm output function；
• Light penetrability power（Receiving light intensity of receiver）,directive function, easy for on-site installation and maintenances；
• RS485series communication meet customers’ different task requirement by initial setting and meanwhile acquire information on every light beam and system working status；
• Reliable separation for vehicles, the reliability is high to 99.9% under fine whether and not less than 99.5% even under rain snow or fog whether；
