De scrip tion
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.
