Product Bulletin OPB815L July 1997 Deep Gap Slotted Optical Switch Type OPB815L Features • Non-contact switching • Printed circuit board mounting • 0.375" (9.53 mm) wide slot • 0.430" (10.92 mm) deep slot Description Absolute Maximum Ratings (TA = 25o C unless otherwise noted) The OPB815L consists of an infrared emitting diode and an NPN silicon phototransistor mounted in a low cost plastic housing on opposite sides of a 0.375" (9.53 mm) wide, 0.430" (10.92 mm) deep slot. Phototransistor switching takes place whenever an opaque object passes through the slot. Available with wire leads as OPB815W.
