Sick has taken a leading position in the market segment of medium-range distance measurement with the new DT20 Hi distance sensor.

With its laser light transmitter and CMOS receiver element, the analogue distance sensor masters all surfaces from white to black, from matt to glossy with high immunity to ambient light.

The three versions of the DT20 Hi distance sensor for the measurement ranges of 50 - 150 mm, 100 - 300 mm and 10 - 600 mm, offer top values regarding accuracy (up to +/- 0.5 mm), reproducibility (up to +/- 0.2 mm) and resolution (< 0.1 mm).

A display shows the user-friendly Setup menu. The new type of plug concept allows connection of the distance sensor at any angle through 90°. During operation, the robust metal housing protects the sensor from mechanical stresses.

A suitable solution for numerous distance applications:

Sick’s experience in distance measurement with a broad product portfolio, from the µ-range to km distances is reflected in the DT20 Hi distance sensor.

In “classic” applications, such as the regulation of winding processes, the positioning of robots or other objects, the classification of screws and other metallic components, or surface quality inspections, the analogue distance sensor offers expanded measurement availability and functional reserves.

Some of the various applications that can be implemented with the DT20 Hi distance sensor include the highly accurate positioning of gantry units or solutions for the automatic laying of flooring and tiles.

It is expected that the precision and user-friendliness of the DT20 Hi distance sensor will open up further new areas of use.

Questions about this article

14/03/2012 - The measurement range of the DT20-P224B is 100-1000mm on an object with between 6 and 90% remission. The surface can be diffuse and having a highly reflective surface does not increase the range. Resolution is 0.5mm up to roughly 600mm and then 1.0mm up to 1000mm. Accuracy and reproducibility are application dependent but have been shown in the laboratory to be +/-2mm accuracy and +/-1mm reproducibility up to 600mm.
