E3MC
E3MC
Adjustment of Sensing Distance of General-purpose
Fiber-optic Type
Unlike the E3MC-A or E3MC-X, the E3MC-Y may require
adjustment of its sensing distance depending on the reflection
rate. This also applies to the through-beam type.
Bring the fiber head as
close as possible to the workpiece
and conduct teaching.
Feed workpieces and
check if they are detected.
Excessive light. Move the
head away from the work-
piece and find a position
where teaching is accepted.
This position is the optimum
distance.
OK: All Detection Level
Indicators (green) illuminated.
NG: All Threshold
Indicators (red)
flashing.
REGISTERED COLOR SELECTION (BANK SELECTION INPUT)
Single-Output Models ONLY (E3MC-A
/E3MC-X
/E3MC-Y
)
The E3MC in RUN mode offers bank selection with external inputs by combining bank selection input 1 (yellow) and input 2 (green). The
selected bank is active when the indicator is illuminated.

EXTERNAL SYNCHRONOUS INPUT FUNCTION (See Note.)
The measurement results will be directly output to the control output if the input from the external synchronous input terminal (pink) is set
to OFF. The output will hold the previous status if the input of the external synchronous input terminal is set to ON. External synchronous
input is valid in RUN or ADJ mode.

Output on hold
Output on hold
This status can be on
hold by an external
synchronous input. It
will be released by
setting the external
synchronous input to
OFF.
This status can be on
hold so that unwanted
color objects can be
ignored while they are
passing the sensing
range.
Note: External Synchronous Input: Latches sensor output in existing state when ESI is on. For example, if sensor output is on when ESI
is on, the output(s) will remain on until ESI is turned off, regardless of target presence or absence.
For NPN models, ESI is turned on by connections to 0V.
For PNP models, ESI is turned on by connections to +V.
