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-
sion will be possible.

1. Do not short-circuit any output terminal with the posi-
tive terminal, otherwise the internal elements of the
B7A will be damaged.
2. Logic output processing and error output processing
methods can be selected with the selectors. The se-
lectors are not required when the B7A is used with its
output fixed to the output logic.
