I SLITS FOR THROUGH-BEAM
Using slits reduces the sensing distance and allows smaller
objects to be detected.
Three pairs of slits are supplied with E3HF-1E1 and E3HF-1E2
sensors. The slits are decals that can be peeled off the protective
backing sheet and applied to the emitter and receiver. See table
below for dimensions of slit openings.
