3.2 Product features
The OLS20 line guidance sensor is an opto-electronic sensor which detects the line
center point of up to three luminescent tracks. To do so, the sensor stimulates the
guide track(s) with blue light and detects the remitted light using a receiver array.
This track is typically conventional adhesive tape or a colorful luminescence track. It is
not necessary to teach in the sensor.
For additional information on the adhesive tape and bar code labels recommended by
SICK, see the product accessories at www.sick.com/ols20.
In addition, the sensor reads 1D codes in “interleaved 2/5” format attached perpendic‐
ular to the track.
