Description:
Slotted optical switches in the OPB852, and OPB853 series consist of an infrared emitting 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 emitter 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.
Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for

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) Methanol and isopropanol are recommended as cleaning agents. Housings are soluble in chlorinated hydrocarbons and
ketones. Highly activated, water soluble fluxes may attack housings in some situations.
(4) All parameters tested using pulse technique.
