PF21 series Mini-type Photoelectric Sensor is one new and upgraded product. It includes through beam type, polarized reflective type and diffused type.
The compact design ensures the application and installation at limited space, The detection distance of opposed type is up to 15m, Polarized sensor with high anti-interference performance, The diffused type photocell sensor with background suppression function can detect the Reflective surface object accurately.
The PF21 series products are widely applied to different business fields such as automatic doors, warehousing and logistics, intelligent parking, access gates and other scenarios.
