The turnstile gate infrared beams sensor should be kept clean and in good condition during use, especially the spherical emitting part of the front end should not have contaminants such as dirt, nor be damaged by friction, otherwise, the turnstile gate infrared beams sensor will emit The infrared light will produce reflection and scattering phenomenon, which directly affects the transmission of infrared light, which may reduce the sensitivity and remote control distance of the remote control, or may completely fail.

During the working process of the turnstile gate infrared beams sensor, it is necessary to ensure that the parameters of the infrared photoelectric sensor shall not exceed the limit value. Therefore, when replacing the model of the turnstile gate infrared beams sensor, we should pay attention to the model and parameters of the original transmitting tube and receiving tube, which cannot be replaced at will. In addition, the current limiting resistance of the infrared emission tube cannot be arbitrarily changed.
Since the infrared light wavelength range of the turnstile gate infrared beams sensor is quite wide, the wavelength model of the infrared transmitting tube and the infrared receiving tube must be matched, otherwise, the sensitivity of the remote control will be affected, and even loss of control will be caused. Therefore, in the process of using the turnstile gate infrared beams sensor, it is necessary to understand the wavelength parameters of the infrared light signal radiated by it, so as to facilitate the maintenance and replacement in the later period.
