Notes:
1. Unspecified tolerance
shall be ±0.2 .
2. Measurement in the bracket is
that of lead pin at base the mold.
3. Dimension in parenthesis are
show for reference.
4. Please be carefully not to receive
external disturbing light because
the top and back face emitter and
detector element isn't covered by case.
