Note: 1. The wire colors have been changed in accordance
with
the revision of the Japanese Industrial Standards
for photoelectric sensors and proximity sensors. The
colors
in parentheses refer to the old colors.
2. Do
not short-circuit the SIG terminal with
a positive or
negative
power supply terminal, otherwise the
internal
elements
of the
B7A will be damaged and no transmis
