APPLICATIONS
Level check within the hopper
The distance to the object can be set
to enable residual amount sensing in
the hopper regardless of color.
Conrmation of the passage of
packages on a conveyor belt
Can accurately detect packages even
if they vary in
size and color.
Equipped with both NPN and PNP outputs
EQ-51□
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.
VARIETIES
Multi-voltage
EQ-50□
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.
Convenient timer function models
Types with an ON-delay / OFF-delay timer available.
OFF-delay, e.g. useful when the response of the
connected device is slow, ON-delay, e.g. useful to detect
objects that take a long time to move.
BGS / FGS functions make even the most challenging settings possible!
FUNCTIONS
When object and background are separated
BGS (Background suppression) function
The sensor judges that an object is
present when light is received at position
A of the light-receiving element (2-segment
element).
This is useful if the object and background
are far apart.
Not affected if the background color changes
or someone passes behind the conveyor.
When object and background are close
together
When the object is glossy or uneven
FGS (Foreground suppression) function
The sensor judges that no object is present
when light is received at position B of the light
receiving element (2-segment element) (The
conveyor is detected). This function is useful
if the object and the background are close
together or if the object is glossy or uneven.
However, sensing is impossible if there is no
background (conveyor, etc.).

• Operation: ON-delay, OFF-delay
• Timer period: 0.1 to 5 sec.
