Omron E3FA-TP21: through-beam set, 20 m, PNP output, M12 connector.
The Omron E3FA-TP21 is an E3FA through-beam set photoelectric sensor with a nominal sensing distance of 20 m. This M12 connector model uses Red LED, 624 nm and PNP open-collector output; the through-beam version is a matched emitter and receiver set. Omron specifies 10–30 VDC, 0.5 ms response and IP67/IP69K protection. Not required Confirm target characteristics and controller compatibility for the installation.

Engineering suggestions require suitability checks for your installation.
Detect products as they pass a machine or conveyor sensing point.
Position the through-beam set sensor within its rated 20 m range and connect the PNP output to a compatible input.
Provide a photoelectric switching point for counting or sequence confirmation in an automated station.
Use the M12 connector and red led, 624 nm configuration; verify any specified reflector and set Light-ON or Dark-ON logic by wiring.
