EQ50Ⅺ
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.
EQ51Ⅺ
Impervious to variations color or angle
Introducing the new DC-voltage type
equipped with BGS / FGS function
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.
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.
Refer to p.196 for the BGS / FGS functions.
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.

BGS / FGS FUNCTIONS MAKE EVEN THE MOST CHALLENGING SETTINGS POSSIBLE!
The BGS function is best suited for the following case
Background not present
BGS (Background suppression) function
When object and background are
separated
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.
OFF
Light received at element
B or light not received
ON
Light received at
element A

Element B
Moving object

Setting distance
The FGS function is best suited for the following case
Background present
FGS (Foreground suppression) function
When object and background are close
together
When the object is glossy or uneven
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.)..

PRECAUTIONS FOR PROPER USE
• 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 a safety sensor. Its use is not
intended or designed to protect life and prevent body
injury or property damage from dangerous parts of
machinery. It is a normal object detection sensor.

• 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).
Care must be taken regarding the sensor mounting direction with
respect to the object’s direction of movement.
•
• 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 N⅐m.

PRECAUTIONS FOR PROPER USE
Wiring
Part description
• Make sure that the power supply is off while wiring.
Stability indicator (Green)
• 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.
Distance adjuster (2-turn)
OFF-delay timer adjuster (Note 2)
• 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 N⅐m.
Operation mode switch
Description
• Verify that the supply voltage variation is within the rating.
Detection-ON mode is obtained when the switch
is turned fully clockwise (L side).
• 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.
Detection-OFF mode is obtained when the switch
is turned fully counterclockwise (D side).
• 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.
Note: Turn the operation mode switch gradually and lightly with the attached
screwdriver. Turning with excessive strength will cause damage to the
adjuster.
• 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 (DC-
voltage type: 1 kV), the internal circuit will be damaged, and a
surge suppressing element should be used.

PRECAUTIONS FOR PROPER USE
Distance adjustment
Timer function (EQ-5ⅪT only)
• EQ-5ⅪT 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.
•
For DC-voltage type, be sure to set the BGS / FGS function before
distance adjustment. If the setting is done after the distance ad-
justment, the sensing area is changed.
• 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.
• Turn the distance adjuster gradually and lightly with the attached
adjusting screwdriver. Turning with excessive strength will cause
damage to the adjuster.

Stability indicator
DC-voltage type • FGS select
• 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.

In the state where the sensor detects the back-

• 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.
The optimum position to stably detect objects is
the center point between a and b .
• 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.
