Omron E3B2-D2M4D-US Photoelectric Sensor, Timer Relay

Omron E3B2-D2M4D-US is a diffuse photoelectric sensor with an integrated timer relay adjustable from 0.5 to 20 seconds. That timer is the headline feature—if you need delayed switching from a photoelectric trigger, this part handles it without an external timer module. The diffuse sensing means the emitter and receiver are in the same housing; it triggers when reflected light from the target is detected. No separate reflector required.
