Optical displacement sensor
Bloomington, Minn. -Sensor and measurement system in one package, OD optical displacement sensor uses principle of triangulation. Light emitted from the sender hits the object bouncing back to the sensor at an angle. The angle of reflection and position of light spot determine distance to object. OD can calculate down to 3 microns (0.00012-in.). Sick offers sensors with either LED or laser light sources. Both models include teach-in plus analog output.
