Proximity sensor handles tough surfaces
A
SICK (UK) product story
Edited by the Engineeringtalk editorial team

The DT20 Hi analogue distance sensor offers accuracy up to +/-0.5mm, reproducibility up to +/-0.2mm and a resolution of less than 0.1 mm, all thanks to its superior CMOS technology and class II laser.
With its laser transmitter and advanced CMOS receiver, the new DT20 Hi analogue distance sensor from Sick (UK) masters almost all surfaces - from white to black, matt or glossy - with extremely high immunity to different ambient light conditions.
Engineers and designers benefit by spending less time commissioning the system due to its tolerance of different surface types and lighting conditions.
Ideal for distance measurement applications where the ultra-high precision of an OD sensor is not necessary, the DT20 Hi is available in three versions, 50 to 150mm, 100 to 300mm and 100 to 600mm.
It offers accuracy up to +/-0.5mm, reproducibility up to +/-0.2mm and a resolution of less than 0.1 mm, all thanks to its superior CMOS technology and class II laser.
It also includes scaleable analogue and switching outputs.
A clear LCD display shows the distance to the target in mm as well as providing access to a user-friendly set up menu including all the necessary information for the sensor's easy to use teach function.
A new type of plug concept allows the sensor's connector to be rotated through any angle up to 90 degrees and a robust metal housing protects the sensor from mechanical stresses and adverse environmental conditions.
The DT20 Hi can be applied in any application requiring a method of accurately determining the distance to an object irrespective of surface structure.
These can include measuring the diameter of coils of paper or metal, the classification and sorting of components based on their size and quality inspection operations such as those measuring flatness of paper or metal products.
Larger-scale applications range from the accurate positioning of gantry units to solutions for the automatic laying of flooring and tiles.
