Omron E3FA-TP11 2M is a PNP through-beam photoelectric sensor with a 20 m sensing distance and pre-wired 2 m cables. It comes as a set of a separate emitter (E3FA-TP11-L 2M) and receiver (E3FA-TP11-D 2M), and detects any object that breaks the beam between them, which makes it reliable for long distances and wide openings. For the same sensor with NPN output, see the E3FA-TN11 2M. It is part of the Omron E3FA Series. Explore more Omron photoelectric sensors.
