Transmissive Optoswitch
Slotted Switch — 0.425 High
VTL23DxA Series
PRODUCT DESCRIPTION
This series of interrupter type transmssive optoswitches combines an infrared emtting
diode (IRED) with an NPN phototransistor in an opaque plastic case with two mounting
tabs. Visible light blocking dust covers are provided over the .04" (1.0 mm wide molded-
in apertures. Smaller width external aperture covers are available to increase position
sensing resolution. These devices are furnished with P.C.board mount leads.
