PRECAUTIONS FOR PROPER USE
Part description
Multi-voltage type (L-ON / D-ON mode only)
DC-voltage type
Description
Operation mode switch
Detection-ON mode is obtained when the switch
is turned fully clockwise (L side).
Detection-OFF mode is obtained when the switch
is turned fully counterclockwise (D side).

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.
Depends on a selection of either BGS or FGS function, the out-
put operation changes as follows.

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 N⅐m.
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 (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.

When assembling the conduit connector, pay attention to the direction
of the gland packing.
Furthermore, in order to maintain water-resistance, fit the gland
packing such that the seating surface of the gland packing contacts
the packing holder part of the terminal cover evenly.

Note:
Use crimp terminals with insulating sleeves.

Notes: 1)
2)
The operation mode switch of the DC-voltage type is the DIP
switch. Refer to ‘DC-voltage type’ of ‘Operation mode switch’
for details.
Incorporated on EQ-5ⅪT only.
Note: Turn the operation mode switch gradually and lightly with the attached
screwdriver. Turning with excessive strength will cause damage to the
adjuster.
