Description
The OPB621 slotted optical switch
consists of an infrared emitting diode and
a PIN photodiode.
The low tr/tf of the PIN photodiode is
ideal for high speed operation. The
polysulfone housing is opaque to visible
light but transmissive to infrared. The
sensitivity to ambient radiation is
minimized.

NOTES:
(1) RMA flux is recommended. Duration can be extended to 10 seconds maximum when flow
soldering. Maximum 20 grams force may be applied to leads when soldering.
(2) Derate linearly 1.33 mW/°C above 25°C.
(3) Methanol and isopropanol are recommended as cleaning agents. Plastic housings are
soluble in chlorinated hydrocarbons and ketones.
