The light curtain is a safety device for intrusion detection, which is commonly used in industrial automation production and safe manufacturing, and is also useful in some special environments of life. For example, elevators, but the light curtains generally used in elevators belong to ordinary types of light curtains, while in industry, safety light curtains with a certain level of safety are often used. Light curtains work on the principle of photoelectric induction and usually consist of multiple pairs of infrared sensors with transmit and receive functions to form the physical part of their detection.
In the elevator light curtain, there are generally more than 30 pairs of infrared transmitting and receiving tubes, and they are respectively located on both sides of the elevator car door. The beam emitted by these infrared sensors during operation will form a densely interlaced "protection net" in the range of 20mm~1806mm. When no obstacle enters the space, all the emitted beams can reach the receiving tube normally. Therefore, the elevator The control section will not get a "intrusive" detection signal. Once an object blocks any of the light, it will cause an "abnormal" output corresponding to the infrared receiver, which is detected by the circuit and controls the elevator to reopen the car door. Until the passengers or obstacles leave the warning area, they can be closed normally, avoiding accidents or accidents caused by accidents.
Honeywell offers a wide range of infrared sensors in a variety of enclosures and enclosures for potential use in printers, copiers, recording and data storage systems, motion control, automated scanning, and medical devices. These products are not only cost-effective, but also stable in performance.
