SICK AG WT 24

A photoelectric proximity sensor uses a light-beam generator, a photodetector, a special amplifier, and a microprocessor. The light beam reflects from an object and is picked up by the photodetector. The light beam is modulated at a specific frequency, and the detector has a frequency-sensitive amplifier that responds only to light modulated at that frequency. This prevents false imaging that might otherwise be caused by lamps or sunlight. If the robot is approaching a light-reflecting object, its microprocessor senses that the reflected beam is getting stronger. The robot can then steer clear of the object. This method of proximity sensing won't work for black objects, or for things like windows or mirrors approached at a sharp angle.

This Photo electric proximity switch has features such as background suppression, infrared light-DC, rotatable plug by 90 degrees, terminal chamber, and explosion protection EEx ia IIC T6. Scanning distance equates to 300...2000 mm, adjustable and 150...600 mm adjustable.
