Caution
Mounting
The EE-SX is a Sensor to be built into equipment. Therefore, no
special
protective measures
have been taken to protect the EE-SX
from external light disturbance. Make sure that the EE-SX is not
affected by incandescent lamps or other light sources that may
cause external light disturbance, otherwise the EE-SX may mal-
function.
Be
sure to mount the Sensor securely
to flat plates. The characteris
-
tics
of the Through-beam Sensor change if the slot is deformed.
Use
M3.0 screws when mounting the EE-SX. Be sure to use spring
washers with the screws so that the screws will not loosen. The
tightening torque applied to each screw must be no more than
0.59 N
S
m (6 kgf
S cm).
Make
sure that nothing will
come into contact with the sensing ele
-
ment
of the Sensor
. If the sensing element has
scratch damage, the
characteristics
of the Sensor will decrease.
Make
sure that the EE-SX is securely mounted and not loosened
by
vibration or shock.
Wiring
Countermeasures Against Surge
If
the power supply has surge voltage, connect a Zener diode with
-
standing 30 to 35 V or 0.1 to 1-
µ
F capacitor in parallel to the power
supply
to absorb the surge voltage.
0.1
to 1
µF
If
the load is a relay or other small inductive load, connect the load to
the
EE-SX as shown below
. Be sure to connect a diode for
counter-
voltage
absorption.
Relay
OUT
Do
not wire power lines or high-tension lines alongside the lines of
the
EE-SX in the same conduit, otherwise the EE-SX may be dam
-
aged
or malfunction due to induction. Be sure to wire the lines of the
EE-SX
separately
from power lines or high-tension lines or lay them
in
an exclusive, shielded conduit.
Voltage Output
A Sensor with open collector output can
be connected to a device
with voltage-input specifications by connecting a resistor between
the
power supply and output terminals as shown in
the following cir
-
cuit
diagram. The resistance of the resistor is normally 4.7 k
Ω
and
must
withstand a power of 0.5 W at 24 V and 0.25 W at 12 V
.

Others
Do
not wire the EE-SX while power is applied, otherwise the EE-SX
may
be damaged.
Do
not install
the EE-SX in the following locations, otherwise the EE-
SX
may be damaged or malfunction.
Locations with excessive dust
Locations with corrosive gas
Locations where water
, oil, or chemical is directly sprayed
Outdoors or locations exposed to direct sunlight
Make sure that the operating ambient temperature is within the
rated
range.
The Sensor may be soluble in organic solvent, acid, and alkaline,
aromatic hydrocarbon, and chlorinated aliphatic hydrocarbon sol-
vents.
The characteristics of the Sensor may decrease as a result.
Therefore,
make sure that the Sensor is free from these solutions.
