PRECAUTIONS FOR PROPER USE
Wiring
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.
Screw for terminal cover fixing
Screwdriver
To maintain water-resistance, the cable should have an outer
diameter between "9 to "11 mm
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 (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.
Conduit connector construction and cabling
Conduit connector
Gland packing (Note)
Note: 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.
The size of conduit is M20
If pressure terminals are to be used, affix the connected
pressure terminals to a terminal (M3.5 screw).

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