Re: Range Finder?
We have also tested laser range finders, specifically a Sick DT50, which is similar to the previously listed Automation Direct version with a longer range. This is a "time of flight" Class 1 laser that outputs a distance in mm, up to 20,000mm or 20 meters (65ft). We have found that they do not sense the polycarb backboards, walls, driver station windows, etc. They do work on shiny objects such as the diamond plate. They have a very focused spot size and therefore are only accurate within the inch area they are pointed at. Just be aware if you are trying to sense a field object that is made from polycarb that it will not sense it.
Measurement range: 200 … 20,000 mm
Resolution: 1 mm
Repeatability : ± 1 mm
Accuracy: ± 7 mm
Output rate: 2 ms
Resistance to ambient light: 40 klux
Operating temperature: -30 … +65 °C
Analogue output: 4 … 20 mA and 1 switching output
