Product Bulletin OPB817 February 2001 Slotted Optical Switch Type OPB817 Features • .20”(5.08 mm) wide gap • 24”minimum, 26 AWG wire leads • Dust protection • .86”(21.8 mm) deep slot Description The OPB817 consists of an infrared emitting diode and an NPN silicon phototransistor mounted in an opaque housing with clear windows for dust protection. The extended deep slot allows for a longer reach of the optical center line from the mounting plane, .90” (22.86 mm). Internal apertures are .010” x 0.06”for the phototransistor “S side” and .050”x .06” for the LED “E side”. Custom electrical, wire or cabling is available. Contact your local representative or Optek for more information.
