Precautions
MOUNTING
!
Caution
•
The EE-SX77/87 is a photomicrosensor that should be built
into equipment. For this reason, no special protective mea-
sures have been taken to protect the EE-SX77/87 from ex-
ternal light disturbance. Avoid malfunction by ensuring that
the EE-SX77/87 is not influenced by incandescent lamps or
other light sources that may cause external light distur-
bance.
TO AVOID DAMAGE
•
Do not use the EE-SX77/87 at voltage exceeding the rated
voltage range.
•
•
Mount the photomicrosensor securely to flat plates. The
characteristics of the through-beam sensor change if the
slot is deformed.
Use M3 screws when mounting the EE-SX77/87. 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 m (6 kgf cm).
•
•
Make sure that nothing will come into contact with the sens-
ing element of the sensor. If the sensing element has
scratch damage, the operating characteristics of the photo-
microsensor will decrease.
•
Do not make mistakes in wiring, such as mistakes in polarity.
Brown

Securely mount the EE-SX77/87 to prevent loosening by
vibration or shock.

OPERATING ENVIRONMENT
•
•
Do not connect the EE-SX77/87 while power is applied, or
the EE-SX77/87 may be damaged.
•
Do not short-circuit the load (i.e., do not connect a power
supply directly to the Sensor) as shown below.
Do not install the EE-SX77/87 in the following locations to
avoid malfunction or damage:
Load
short-circuiting
A. Locations with excessive dust
B. Locations with corrosive gas

C. Locations where water, oil, or chemicals are directly
sprayed
Black

D. Locations exposed to direct sunlight
•
•
Make sure that the operating ambient temperature is within
the rated range.
The photomicrosensor may be soluble in organic solvent,
acid, and alkaline, aromatic hydrocarbon, and chlorinated
aliphatic hydrocarbon solvents. The characteristics of the
photomicrosensor may decrease as a result. Make sure that
the photomicrosensor is free from these solutions.

WIRING
Voltage Output
A photomicrosensor 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 circuit diagram. The value of the resistor is
normally 4.7 kΩ and must withstand a power of 0.5 W at 24 V
and 0.25 W at 12 V.
For Surge Prevention
If the power supply has surge voltage, connect a Zener diode
withstanding 30 to 35 V or a 0.1 to 1-µF capacitor in parallel to
the power supply to absorb the surge voltage.
