Omron E3FA-TP12 2M is a PNP through-beam photoelectric sensor with a 15 m sensing distance, an infrared LED and pre-wired 2 m cables. It comes as a set of a separate emitter (E3FA-TP12-L 2M) and receiver (E3FA-TP12-D 2M), and detects any object that breaks the invisible infrared beam between them. For a longer 20 m range with a visible red beam, see the E3FA-TP11 2M. It is part of the Omron E3FA Series. Explore more Omron photoelectric sensors.
