■General terms and conditions ............. F-7
Glossary of terms / General precautions
.......
P.1455~ / P.1458~
Long range sensing capability to 2.5 m 8.202 ft
Stable sensing unaffected by color or material
Recognition
Long sensing range
An adjustable range to 2.5 m 8.202 ft allows plenty of
space for installation.
1 m 3.281 ft sensing range type also available. Adjust
the volume easily to suit your needs when using at close
range.
Hardly affected by background objects
Because the sensor doesn’t detect objects outside the
preset sensing eld 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.
Note: Please note that malfunction may occur when there are specular
objects or objects with a mirror-like surface in the background.
Impervious to variations color or angle
The optical system has been optimized. Since the
sensor is hardly inuenced at all by angles or the gloss
of objects compared to the previous model, it is possible
to detect both white objects and black objects at almost
a constant distance.
Convenient terminal block type
Cabling enabled
by way of a
terminal block
that eliminates
waste.

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.).

•
The tightening torque
should be 0.8 N·m or less.
•
Care must be taken
regarding the sensor
mounting direction with
respect to the object’s
direction of movement.
Sensing object Sensing object
Do not make the sensor
detect an object in this
direction because it may
cause unstable operation.
Sensing object
•
When detecting a specular object (aluminum or copper foil,
etc.) or an object having a glossy surface or coating, please
note that there are cases when the object may not be detected
due to a change in angle, wrinkles on the object surface, etc.
•
If a specular body is present in the background, faulty operation may
be caused due to a small change in the angle of the background
body. In that case, install the sensor at an inclination and conrm the
operation with the actual sensing object.
•
When a specular body is present below the sensor, use the
sensor by tilting it slightly upwards to avoid faulty operation.

•
This product is not easily affected by the reected light
intensity since this sensor is the adjustable range reective
type. When the reected light intensity is remarkably low,
the sensing range may be affected. In that case, mount the
sensor, while checking light-up of the stable indicator (green).
•
The mounting screws of the terminal cover and display cover
should certainly be tightened to maintain water-resistance;
the tightening torque of the screws should be 0.3 to 0.5 N·m.

Wiring Part description
Operation mode switch
BGS / FGS function (DC-voltage type only)
• DC-voltage type sensor incorporates BGS / FGS function.
Select either the BGS or FGS function depending on the
positions of the background and sensing object.
• BGS / FGS function is set with the operation mode
switch.
• FGS function is used when the sensing object contacts
the background (conveyor, etc).
• Depends on a selection of either BGS or FGS function,
the output operation changes as follows.
• Check all wiring before applying power since incorrect
wiring may damage the internal circuit. Also, carefully
tighten the terminal screws so that the wires of adjacent
terminals do not touch.
• The mounting hole for the terminal cover xing screws
inclines 70 degrees to the terminal cover, as shown in the
gure below.
To avoid damaging this product or screw, take care when
tightening or loosening a screw.
Notes: 1)
The operation mode switch of the DC-voltage type is the DIP switch.
Refer to ‘DC-voltage type’ of ‘Operation mode switch’ for details.
2) Incorporated on EQ-5□T only.
Note: Turn the operation mode switch gradually and lightly with the attached
screwdriver. Turning with excessive strength will cause damage to the
adjuster.

To maintain water-resistance, the cable should have
an outer diameter between ø9 to ø11 mm ø0.354 to
ø0.433 in with a smooth covering material that allows the
attached conduit connector to be securely tightened; the
tightening torque of the screw should be of 1.5 to 2.0 N·m.
• If an external surge voltage exceeding 4 kV is impressed
(DC-voltage type: 1 kV), the internal circuit will be
damaged, and a surge suppressing element should be
used.
• Prepare the cable end as shown below.

pressure terminals to a terminal (M3.5 screw).
Conduit connector construction and cabling
Note: When assembling the conduit connector, pay attention to the direction
of the gland packing.
Furthermore, in order to maintain water-resistance, t the gland
packing such that the seating surface of the gland packing contacts
the packing holder part of the terminal cover evenly.

PRECAUTIONS FOR PROPER USE
Stability indicatorTimer function (EQ-5□T only)
• Since the EQ-500 series uses a 2-segment photodiode
as its receiving element, and sensing is done based
on the difference in the incident beam angle of the
reected beam from the sensing object, the output and
the operation indicator (orange) operate according to
the object distance.
Furthermore, the stability indicator (green) shows the
margin of the setting distance.
• EQ-5□T incorporates an OFF-delay timer, which is
useful when the response of the connected device is
slow, etc., and an ON-delay timer, which is useful for
detecting objects that move slowly, for example.
• The OFF-delay and ON-delay timers can be used
simultaneously.
• For DC-voltage type, set the DIP switch for the timer
mode to ‘Timer ON’ side.
