SCHEMATIC
DESCRIPTION
The QVE00034 is a slotted optical switch designed for multipurpose non-contact sensing. It consists of a GaAs LED and a silicon
photo-transistor packaged into an injection molded housing and facing each other across a 0.315" (8.0 mm) gap. The housing is
featuring locating knobs for accurate mounting.
