Photoelectric sensors (photocell sensors) are widely used in the gate and door industry. Door sensors are mainly realized using microwave, infrared, or laser detection. Infrared photoelectric sensors and infrared light curtains are most widely used in industrial doors such as high-speed doors, roller shutter doors, and sectional hard high-speed doors. When people or objects 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 the automatic door industry. It responds to the movement of people or objects, thus realizing the automatic door switch control.
PMF50R retro-reflective photoelectric sensor is one popular model used in industry doors such as high-speed doors, roller shutter doors, garage doors, and so on. Different detection ranges can be selected as 7m, 12m,and Supply voltage 10-30V DC & 12-240V DC/AC for selecting which can meet different demands of customers.
