Fuzzy Mutual Interference Prevention Function
If Reflective Sensors are installed side by side, each Sensor may be
influenced by the light emitted from the other Sensors.
The fuzzy mutual interference prevention function of the E3S-C
enables the E3S-C to monitor any light interference for a certain
period before the E3S-C starts emitting light so that the E3S-C can
retrieve the intensity and frequency of the light interference as data.
Using this data, the E3S-C estimates with fuzzy inference the risk of
the malfunctioning of the E3S-C and controls the timing of the E3S-
C’s light emission.
When the risk is low:
The E3S-C waits until there is no light interference and emits light.
When the risk is high:
The E3S-C emits light between each period of light interference.
Cable
Mounting
Output selector *1
The E3S-C uses an oil-resistive cable to ensure oil resistivity.
Do not allow the cable to be bent to a radius of less than 25 mm.
When mounting the E3S-C, do not hit the E3S-C with a hammer, or
the E3S-C will loose watertightness.
Use M4 screws to mount the E3S-C. The tightening torque of each
screw must be 1.18 N·m maximum.

Optical Lock Holes
By inserting screws into the
optical axis lock holes, the
Mounting Bracket will be in the
direction of the optical axis of the
E3S-C.

When mounting the E3S-C with the mounting bracket so that
sensing objects will be in the direction of the mechanical axis, use
the optical axis lock holes.
If it is not possible to mount the E3S-C so that the sensing objects
will be in the direction the mechanical axis, move the E3S-C
upwards, downwards, to the left, or to the right and secure the E3S-
C in the center of the range where the light indicator will be lit, at
which time make sure that the stability indicator is lit.
