The OPB9730 is a slotted optical switch manufactured by TT Electronics. It consists of an infrared LED and a phototransistor, positioned facing each other within a slotted housing. When an object passes through the slot, it interrupts the infrared beam, causing a change in the phototransistor's output. This change can be detected and used for various sensing and control applications.
