The OY120120 Sensor with PNP/NC, Transmitter-Receiver, PIN: 3 is a photoelectric sensor manufactured by IPF ELECTRONIC. Designed for applications such as proximity sensing and object detection, the sensor reflects incident light off of an object and uses the reflected light to detect the presence or absence of the object. It has a non-contact, highly accurate sensing function and a high speed response time. The PNP/NC output is able to be configured to either normally open or normally closed. It has a smart sensing range and a wide variety of detection objects. The IPF ELECTRONIC OY120120 Sensor with PNP/NC, Transmitter-Receiver, PIN: 3 has a compact molded body design and is lightweight.
