The ETC infrared vehicle light curtain has mature technology, simple installation, high-speed response, strong anti-interference ability, and can output data information such as vehicle size, Vehicle passing status, Vehicle tailgating, vehicle counting, etc. It can reliably detect various special vehicles. Mainly used for general highway toll stations, Electronic Toll Collection (ETC), automatic vehicle classification systems (AVC), highway weight based toll collection systems (WIM), fixed over limit detection stations, customs vehicle management systems, etc.

The composition of ETC vehicle type light curtain system :

 ◆ Emitter and Receiver: The transmitter is equipped with a linear arrangement of high-energy light-emitting elements, and the receiver is equipped with the same number of receiving elements as the transmitter. The corresponding photoelectric elements of the transmitter and receiver are synchronously triggered in sequence to detect whether the optical path is conductive. When the car passes through the scanning area, some or all of the light beams are blocked, thus being detected.

◆Protective cover: Made of stainless steel material, providing protection for the separator, equipped with electrically heated glass, temperature controller, and humidity controller. Automatic heating is achieved when the temperature is too high or too low to ensure reliable use of the vehicle separator in humid areas, rainy and foggy weather, and cold seasons.

LHN(C) vehicle infrared light curtain Features

• 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.
