Sick OLM fine positioning sensor
The new Sick OLM distance measurement positioning sensor is designed for high-speed, high-precision positioning of overhead cranes, rail and transfer cars, monorails, shuttles, elevators and other vehicles. Vehicles can be positioned around curves and inclines where traditional laser measurement systems cannot be used.
With the OLM, users can position vehicles with 0.1 mm resolution at distance up to 10 km, providing more than 6 miles of unique positions at increased speed and positioning accuracy. Four LEDs and CMOS camera used in the sensor last twice as long as lasers and rotating mirror technology used in similar sensors and positioning methods, according to Sick.
