■ SLITS FOR THROUGH-BEAM
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.
Using slits reduces the sensing distance and allows smaller
objects to be detected.
