The contactless laser triangulation sensors work according to the angle measurement principle, which enables reliable and highly precise measurement in the close range up to 1,000 mm. The triangulation sensors deliver stable measured values regardless of color, shape, rough and textured surfaces.
 

Time-of-flight laser distance sensors (ToF) work according to the principle of transit time measurement, which means that they cover large working ranges up to 10,000 mm, so that objects can be reliably detected even at great distances. The ToF sensors are extremely robust against interfering ambient light, which ensures reliable operation.

Distance sensors are suitable for the detection, differentiation and measurement of objects using ultrasound. Different operating modes, such as synchronous, multiplex or through-beam mode, can be set via the display or centrally via IO-Link, and different output variants and formats enable a wide range of possible applications.

Retro-reflex sensors for transparent objects work with red light to detect even weak absorption of the signal level by the object. They have a function for dynamic readjustment of the switching threshold, which is automatically adjusted in the event of contamination, temperature fluctuations or aging.
