Transmissive Optoswitch VTL23DxA Series Slotted Switch — 0.425 High PRODUCT DESCRIPTION This series of interrupter type transmissive optoswitches combines an infrared emitting 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 moldedin apertures. Smaller width external aperture covers are available to increase position sensing resolution. These devices are furnished with P.C.board mount leads. ABSOLUTE MAXIMUM RATINGS Maximum Temperatures Storage and Operating: Lead Soldering Temperature: -40°C to 85°C 260°C (1.6 mm from case, 5 seconds max.)
