Light sensors, such as those used in the electronics industry, typically consist of a light source - usually an infrared LED - and a light-sensitive receiver such as a photodiode. In the case of transmissive photointerrupters, the transmitter and receiver are integrated opposite each other in a housing. An object that interrupts the light beam is thus reliably detected. Photo-reflectors, on the other hand, detect light that is reflected back from the object, which is particularly useful for barcode readers and position checks.
In close cooperation with leading manufacturer Okaya Electric Industries, Rotima AG offers a wide range of light sensors that are characterized by their precise optical alignment, compact design and high interference immunity - ideal for demanding industrial applications.
