Photoelectric sensors (photocell sensor) are widely used in gate and door industry. Door sensors are mainly realized by means of microwave, infrared or laser detection. Infrared photoelectric sensors and infrared light curtain are most widely used in industrial doors such as high speed door, roller shutter door and sectional hard high speed door. When the people or object are detected by the infrared device (photocell or light curtain), no matter whether people move or not, as long as they are within the detecting range of sensors and light curtains, they will react and give the control output to protect people or objects from being pinched. Microwave radar is also a widely-used product in automatic door industry. It responds to the movement of people or objects, thus realizing the automatic door switch control.
