Detection light curtain: divided into transmitter and receiver. The transmitter has built-in linearly arranged high-energy light-emitting elements, and the receiver has the same number of receiving elements as the transmitter. The corresponding photoelectric elements of the transmitter and the receiver are triggered in sequence and synchronously to detect whether the light path is on. When the car passes through the scanning area , Part or all of the beam is blocked, and thus is detected.
Ir sensor light curtain advantage
3. The optical curtain sensor stops the transaction (for example, when to pay at the toll booth).
4. The light curtain transmitter receiver is installed on both sides of the toll lane, and the radiographic grating is perpendicular to the lane.
3. The resolution of light curtain vs area sensor of 1 mm can avoid errors caused by wrong movement caused by sunlight, mosquitoes and sludge.
4. Vehicle separation light curtain automatically checks for faults and ignores faulty beams. These beams can output alarm signals while maintaining normal operation.
5. Infrared vehicle separator adopts high-energy, high-penetration photoelectric cell, which is easy to install and maintain.
