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 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.
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.
Multi-voltage type (L-ON/D-ON mode only)
DC-voltage type
Operation mode switch
Description
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).

•
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.

•
If pressure terminals are to be used, affix the connected
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, fit the gland
packing such that the seating surface of the gland packing contacts
the packing holder part of the terminal cover evenly.
