The E3S-1LE21 is an Omron photoelectric sensor — a through-beam or retroreflective unit (the exact sensing mode is not specified in the listing) used to detect the presence or absence of an object in an industrial line without physical contact.
Not without checking the mounting and wiring first. The E3S-1LE21 weighs 0.06 kg versus the E3FB-DP22 at 0.23 kg — a 4× weight difference — and the two are different mechanical families. The E3FB series typically uses a different barrel diameter and bracket pattern than the E3S. Confirm the physical footprint and connector pinout before assuming a drop-in swap.
