Operation
J SENSITIVITY ADJUSTMENT
Unlike conventional photoelectric sensors, the variation in the sensitivity of E3S photoelectric sensors is minimal. This means the
sensitivity can be adjusted on only a single photoelectric sensor, and then the adjusters on the other photoelectric sensors can be set to
the same scale position. There is no need to adjust the sensitivity of each photoelectric sensor individually.

Place target at the desired sensing

sensitivity adjuster clockwise until the
Light Incident indicator (red LED)
turns ON. Position A designates the
point at which the LED has turned ON.

Set the sensitivity indicator to the
position between Positions A and B (in
some cases, Positions A and B are
opposite of the above example). The
photoelectric sensor will then work
normally if the stability indicator
(green) is lit with and without the
target. If it is not lit, stable operation
cannot be expected, in which case a
different detection method should be
applied.
