PF21 series Mini-type Photoelectric Sensor is one new and upgraded photo eye product. It includes through beam type, polarized reflective type and diffused type sensor. The compact design ensures the application and installation at limited space; different detection distance and type make such product widely applied to different business fields such as automatic doors, warehousing and logistics, intelligent parking, access gates and other scenarios.

The photo sensor play important roles in judging whether the workpiece has size detection, stacking height detection, liquid level control, product counting, quality inspection, fixed length shearing, small material detection, etc. Following we will give an instruction on PF21 photo sensor typical application on warehouse logistics conveyor belt system.

The opposed type photoelectric sensor is the most common product for conveyor belt to realize object detection. G-TEK PF21T series detection distance with 15m and 30m options, can meet different size conveyor belt .

The PF21RS photoelectric sensor is one Polarized sensor with high anti-interference performance, the reflective type makes the installation easier than the opposed type, the 4m detection distance can meet most conveyor system demand , then such type sensor because more popular for the customers.

The PF21B diffused type photocell sensor with background suppression function can detect the Reflective surface object accurately, with 150mm, 350mm and 1000mm distance for selecting. The background suppression ensures the different color object effective detection on the conveyor belt.

G-TEK Sensor is one professional sensor manufacturer and warehousing logistics solution provider, besides the photo sensor, we also provide measurement light curtain , LIDAR , laser ranging sensor for logistics solution , welcome your attention to more of our sensor applications.
