Precautions
Do not use the EE-SX at voltage exceeding the rated voltage range,
otherwise the EE-SX may be damaged.
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.

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.
