Slotted Optical Switch
OPB816Z
Features:
0.20" (5.1 mm) wide gap, 0.61" (15.5 mm) deep slot
Wire length 24" (609 mm) minimum, 26 AWG
Dust protection
Two mounting tabs
Description:
The OPB816Z slotted switch consists of an infrared emitting diode and an NPN silicon phototransistor mounted in
an opaque housing with clear windows for dust protection. Switching of the phototransistor occurs whenever an
opaque object passes through the slot.
The OPB816Z has an 0.61" (15.49 mm) deep slot allowing for a longer reach of the optical center line from the
mounting plane. The phototransistor internal apertures are 0.10" x 0.06" (0.25 mm x 1.52 mm) on the sensor side
("S") and 0.05" x 0.06" (1.27 mm x 1.52 mm) on the emitter side ("E").
Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for
more information.

Notes:
(1) RMA flux is recommended. Duration can be extended to 10 seconds maximum when flow soldering.
(2) Derate linearly 1.67 mW/C above 25 C.
(3) All parameters are tested using pulse techniques.
(4) Methanol or isopropanol are recommended as cleaning agents. Plastic housing is soluble in chlorinated hydrocarbons and
ketones.
(5) Clear dust protection over emitter and sensor apertures.
