Sensing in Food Packaging and Conveying
The sensing characteristics of this application are simple, yet unique: the sensors are positioned directly above a white, highly reflective background and must detect darker, lower contrast objects of varying texture. The EZ-BEAM T18 fixed field sensor is an ideal solution. It has a sharp detection cutoff and is not sensitive to color variations – it will signal the presence of an object within a certain range and ignore the background. The sensor's right-angle housing allows for a low-profile machine design by keeping the cordset connections parallel with the mounting assembly. No range adjustments are needed, after the sensor is positioned over the conveyor at a height that ignores the background while detecting the food tray.
QD model T18 sensors are rated IP69K, and like many sensors in the EZ-BEAM family, they are designed to withstand frequent, harsh washdowns.
