Profile: Banner Engineering Corporate designs, manufactures and distributes photo eyes, sensors & associated products for industrial and process automation. Our laser sensors combine the alignment advantages of a visible sensing beam with the increased sensing range of a laser. They operate on dc or ac/dc (universal voltage). class 1 and class 2 devices are available. Our radar sensors use modulated continuous wave radar to reliably detect moving or stationary targets, including cars, trains, trucks and cargo in weather conditions.
