Slotted Optical Switch
OPB852A1-3
OPB853A1-3
Features:
Inexpensive opaque plasꢁc housing
Choice of transistor (OPB852) or photodarlington (OPB853) output
0.125” (3.18 mm) slot width
0.290” (7.37 mm) lead spacing
Apertured for high resoluꢁon
Descripꢀon:
Sloꢀed opꢁcal switches in the OPB852, and OPB853 series consist of an infrared emiꢂng diode and a NPN silicon
phototransistor or photodarlington, mounted on opposite sides of a 0.125” (3.175 mm) wide slot. The OPB852A, OPB852B
and OPB852C have phototransistor output, while the OPB853A, OPB853B and OPB853C have photodarlington output.
On each of these devices, the emiꢀer has a molded-in aperture of 0.050” x 0.050” (1.270 mm x 1.270 mm) and the
phototransistor (OPB852) or photodarlington (OPB853) has a molded-in aperture of 0.010” x 0.050” (0.254 mm x 1.270
mm).
Phototransistor or photodarlington switching occurs when an opaque object passes through the slot.

Notes:
(1) RMA flux is recommended. Duraꢁon can be extended to 10 seconds maximum when flow soldering.
(2) Derate linearly 1.67 mW/° C above 25° C.
(3) Methanol and isopropanol are recommended as cleaning agents. Housings are soluble in chlorinated hydrocarbons and ketones. Highly acꢁvated,
water soluble fluxes may aꢀack housings in some situaꢁons.
(4) All parameters tested using pulse technique.
