Home Products Photoelectric Sensors Omron E3FA Series E3FA-TN21 Omron E3FA-TN21 Photoelectric Sensor Omron E3FA-TN21 is an NPN through-beam photoelectric sensor with a 20 m sensing distance and M12 connectors. It comes as a set of a separate emitter (E3FA-TN21-L) and receiver (E3FA-TN21-D), detects any object that breaks the beam between them, and the connectors let you replace a sensor head while keeping the field cable in place. For the same sensor with fixed cables, see the E3FA-TN11 2M. It is part of the Omron E3FA Series . Explore more Omron photoelectric sensors .
