The sensor for optical line guidance
The OLS is a line guidance sensor based on luminescence technology. It detects conventional luminescent adhesive tape regardless of the background, contamination or surface defects and reliably outputs the deviation from the center of the lane. Lane shifts can be made flexibly with adhesive tape and are also possible in small curve radii of up to 0.5 m. In addition, the OLS offers the option of reading 1D codes and thus transmitting various pieces of route information and drive commands in the event of an overrun. A CANopen, RS-485 or IO-Link interface enable simple installation and commissioning. The OLS is therefore the most cost-effective solution for line guidance with a focus on ruggedness and flexibility.

RELIABLE LANE DETECTION
The rugged solution thanks to luminescence
Based on the luminescence principle, the OLS optical line guidance sensor offers increased ruggedness. The OLS can be used with one and the same lane regardless of the surface type and stably detects the lane even when soiled or slightly damaged. This reduces maintenance costs and downtimes of the vehicles.

Reliable lane detection, able to withstand contamination and damage: The OLS offers more process reliability thanks to luminescence technology.

FULLY FLEXIBLE
Flexible line guidance through large reading field and 1D code reading function
Thanks to its large reading field of 180 mm, the OLS is able to stably master curved trajectories even at high speeds and small radii. Even for lane branches or merges it can read up to three lanes. The 1D code reading function allows positioning based on landmarks or the transmission of route commands.


The OLS reads up to three lanes simultaneously and outputs the lane midpoint and lane width. This enables it to correctly detect the branching of a lane or merging of several lanes


The sensor reads 1D codes without difficulty while passing over them, and transmits the four-digit numeric value in the process data to the controller. This makes the use of additional RFID tags unnecessary

Fully flexible line guidance thanks to the large reading field; the simultaneous detection of up to three lanes and the 1D code reading function make further landmarks unnecessary and save time in routing.
