SICK WT23L: Laser technology for detection of very small objects

This high-tech device can detect very small objects with a 2 mm light spot at a distance of 400 mm. It uses a red laser light that is visible to the human eye, making it easy to align and use. The precise background suppression feature ensures that the sensor will only detect the object of interest, even if there are other objects in the background.

The SICK WT23L is a laser photoelectric proximity switch with background suppression. It has a scanning distance of 50 to 800 mm and an adjustable operating distance.
