1. Operating Environment
1) The sensor should be used in an
ambient temperature range of –25 to
+55°C –13 to +131°F.
2) Use an operating voltage in the
range of 9.6V to 30 V DC (includes
peak to peak ripple) for the DC types
and 21.6V to 264V AC or 10.8V to
264V DC for the AC/DC types.
3) The light intensity on the receiver
surface should be less than 3,000 lux
for an incandescent light source and
less than 10,000 lux for sunlight.
4) Use a surge absorber as the internal
circuit may be damaged if external
surge voltages exceed 5..V (for DC
type)/4,000V (for AC/DC type)
[±(1.2T50)µs signal polarity full-wave
voltage].
5) Avoid use in locations with high con-
centrations of steam, dust , corrosive
gases, etc.
6) Use a load relay with a rated operat-
ing voltage of 12V DC or 24V DC for
the DC types. The voltage applied to
the load relay is the operating voltage
of the photoelectric sensor minus the
internal voltage drop (maximum 1.2V
NPN side, 2V PNP side). Voltage fluc-
tuations should be taken into account.
7) The output circuit of the DC type
contains a short-circuit protection cir-
cuit. When controlling loads with a large
inrush current, such as capacitive
loads, be sure the inrush current does
not exceed the maximum output current
capacity. If the short-circuit is activated,
it can be reset either by turning the
power off and then turning it back on, or
by ON/OFF operation.
2. Wiring
1) Check all wiring before applying
power since incorrect wiring may dam-
age the internal circuit.
Also, carefully tighten the terminal
screws so that the wires of adjacent ter-
minals do not touch.
2) Although any cable can be used, a
round cable with a smooth surface and
an outside diameter of 9 to 11 mm .354
to .433 inch should be used and the
cable connector (supplied) shall be
tightened correctly to maintain water-
tight performance. Use a tightening
torque of 15 to 20 N·m {147 to 196
kgf·cm 127.60 to 170.03 lbf·in}.
3) the conduit inlet accepts PF1/2
threads.
4) If crimp terminals are used, crimp the
terminals and then secure with the ter-
minal (M3.5) screws.
5) Tighten the terminal screws with a
maximum torque of 5 N·m{49 kgf·cm
42.53 lbf·in}.
6) Ground the frame ground (FG) termi-
nal and ground (G) terminal when using
a commercially available switching
regurator. If a ground is not connected,
switching noise from the power supply
may result in faulty operation.
7) Wire 0.3 mm20.005 inch2AWG22 or
larger should be used for wiring up to a
length of 100 m 328 ft.
3. Detector
1) Keep the detector surface clean as
excessive dust or dirt on the detector
surface will decrease the margin of the
distance range.
2) The front surface of the lens and
case are made of polycarbonate resin.
Although it withstands water, weak
acids and alkalines, aliphatic hydrocar-
bons, and oils and fats, it is not resis-
tant to ketones, esters, halogenated
hydrocarbons and aromatic hydrocar-
bons.
4. Movement Direction of the target
Take care with the mounting direction
of the photoelectric sensor with respect
to the movement direction of the target.
5. Other cautions
1) When using the supplied mounting
bracket, tighten the mounting screws
with a maximum torque of 8 N·m{78.4
kgf·cm 68.00 lbf·in}. If the supplied
mounting bracket is not used, mount
the sensor on a flat surface.
2) Using a torque of 3 to 5 N·m{29.4 to
49 kgf·cm 25.48 to 42.53 lbf·in}, tighten
the terminal cover and display cover
screws to maintain watertight perfor-
mance.
