Not affected by background objects

Because it can function with 24 to 240 V AC and 12 to 240 V
DC, almost any power supply anywhere in the world will do.

Because the sensor doesn’t detect objects outside the preset
sensing field by using the 2-segment photodiode adjustable
range system, it will not malfunction even if someone walks
behind the sensing object or machines or conveyors are in
the background.

Impervious to variations color or angle

Due to its advanced optical system, the sensor is not affected
by variations in the object’s angle or gloss compared to
conventional sensors.
Moreover, as the difference in sensing range between black
and white varies by only approx. 5 % (Note), sensing can be
performed at a somewhat constant distance even if the
sensing object is black or white.

Introducing the new DC-voltag e type
equipped with BGS / FGS function

We’ve added a DC-voltage type with NPN and PNP
transistor outputs all in one sensor. Its BGS / FGS function
controls any background effects for more stable sensing.

Note: Example of the difference in sensing range between

black non-glossy paper (Lightness: 5) and white non-
glossy paper when the setting distance is set at 2 m

6.562 ft

.

Refer to p.196 for the BGS / FGS functions.
