Unit: mm Using slits reduces the sensing distance and allows smaller objects to be detected. I SLITS FOR THROUGH-BEAM Through-beam Type Light Source Receiver Diffuse Reflective Type 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.
