The Keyence CZ-H52 UV sensor detects the presence of fluorescent agents used in a range of products and packaging materials. It emits a UV light beam from the transmitter in the sensor head; the receiver picks up the visible light reflected by fluorescent materials. The digital UV sensor detects materials invisible to the naked eye, as well as those that can't be detected by ordinary photoelectric sensors.
