Multi-voltage Amplifier Built-in
Multi-voltage 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.
EQ50
Introducing the new DC-voltage 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 nonglossy paper when the setting distance is set at 2 m
6.562 ft.
Refer to p.196 for the BGS / FGS functions.

Level check within the hopper
Even if the lens surface gets somewhat
dirty from dust particles, there is very
little change in the operation field,
rendering stable and consistent
detection even for objects appearing
close to the front surface of the unit.
Waterproof
IP67 protection permits use in
environments where water may splash.
The distance to
the object can be
set to enable
residual amount

BGS / FGS FUNCTIONS MAKE EVEN THE MOST CHALLENGING SETTINGS POSSIBLE!
The BGS function is best suited for the following case
Background not present
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.

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.)..

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 confirm 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 reflected light intensity
since this sensor is the adjustable range reflective type. When
the reflected 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 Nm.

Make sure that the power supply is off while wiring.
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 fixing screws inclines
70 degrees to the terminal cover, as shown in the figure below.
To avoid damaging this product or screw, take care when
tightening or loosening a screw.
To maintain water-resistance, the cable should have an outer
diameter between "9 to "11 mm "0.354 to "0.433 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.
Verify that the supply voltage variation is within the rating.
If power is supplied from a commercial switching regulator,
ensure that the frame ground (F.G.) terminal of the power supply
is connected to an actual ground.
In case noise generating equipment (switching regulator, inverter
motor, etc.) is used in the vicinity of this sensor, connect the
frame ground (F.G.) terminal of the equipment to an actual ground.
Do not run the wires together with high-voltage lines or power
lines or put them in the same raceway. This can cause
malfunction due to induction.
If an external surge voltage exceeding 4 kV is impressed (DCvoltage type: 1 kV), the internal circuit will be damaged, and a
surge suppressing element should be used.
Prepare the cable end as shown below.

packing such that the seating surface of the gland packing contacts
the packing holder part of the terminal cover evenly.

EQ-5T 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.

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 reflected 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.

Take care that the sensor is not directly exposed to fluorescent
light from a rapid-starter lamp or a high frequency lighting device,
as it may affect the sensing performance.
Do not use during the initial transient time (50 ms) after the
power supply is switched on.
This sensor is suitable for indoor use only.
Its distance adjuster is mechanically operated. Do not drop; avoid
other shocks.
Do not use this sensor in places having excessive vapor, dust,
etc., or where it may come in direct contact with water, or
corrosive gas.
Take care that the sensor does not come in direct contact with
water, oil, grease or organic solvents, such as, thinner, etc.
This sensor cannot be used in an environment containing
inflammable or explosive gases.
Never disassemble or modify the sensor.

Distance adjustment
Description
Distance
adjuster
Turn the distance adjuster fully counterclockwise
to the minimum sensing range position. (0.2 m
0.656 ft approx.)
Optimum
position
1
Please an object at the required distance from the
sensor, gradually turn the distance adjuster clockwise to determine point a, where the sensor
changes to the detecting state.
2
Remove the object. Continue turning the adjuster
clockwise until the sensor enters the detecting
state again. Then turn the distance adjuster back
a little untill the sensor returns to the non-detecting state, called point b .
If the sensor does not go into the detecting state
even if the adjuster is turned fully clockwise, point b
is regarded as the maximum position on the scale.
3
The optimum position to stably detect objects is
the center point between a and b.
4
Turn fully
Step
For DC-voltage type, be sure to set the BGS / FGS function before
distance adjustment. If the setting is done after the distance adjustment, the sensing area is changed.

Turn the distance adjuster fully clockwise to the
maximum sensing range position. (2.5 m 8.202 ft
approx., 1.0 m 3.281 ft approx. for EQ-512)
Optimum

1
In the state where the sensor detects the background, gradually turn the distance adjuster counterclockwise, to determine point a where the
sensor changes to the non-detecting state.
2
Place an object at the required distance from the sensor,
turn the adjuster counterclockwise further until the sensor goes into the non-detecting state again. Once entered, turn the adjuster backward a little until the sensor returns to the detecting state, called point b .
If the sensor does not go into the non-detecting state
even if the adjuster is turned fully counterclockwise, point
b is regarded as the maximum position on the scale.
