Note: 1. A sensor with two-wire output
cannot be connected.
2. The wire colors have been
changed in accordance with the
revision of the Japanese Indus-
trial Standards for photoelectric
sensors and proximity sensors.
The colors in parentheses refer
to the old colors.
3. Do not short-circuit the SIG termi-
nal with the positive power supply
terminal, negative power supply
terminal, or a Bjj terminal,
otherwise the internal elements
of the B7A will be damaged and
no transmission will be possible.
