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-
F capacitor in parallel to
the power supply to absorb the surge voltage.

If the load is a relay or other small inductive load, connect it to the
EE-SX77/87 as shown below. You must connect a diode for
counter-voltage absorption.

Do not route power lines or high-tension lines in the same
conduit with the EE-SX77/87 to avoid damage or malfunction due
to induction.
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 k
and must withstand a power of 0.5 W at 24 V
and 0.25 W at 12 V.
