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 the positive power supply terminal, negative power supply terminal, or a B
jj
terminal, otherwise the internal elements of the B7A will be damaged and no transmission will be possible.
