Precautions
J CONNECTION
If the input/output lines of the photoelectric sensor are placed in the
same conduit or duct as power lines or high-voltage lines, the photo-
electric sensor could be induced to malfunction, or be damaged, by
the electrical noise. Either separate the wiring, or use shielded lines
as input/output lines to the photoelectric sensor.
The cord connected to the E3S-C can be extended up to 100 m pro-
vided that the diameter of each wire of the cord is 0.3 mm² minimum.
J POWER SUPPLY
If the standard switching regulator is used as a power supply, the
frame ground (FG) terminal and the ground (G) terminal, on the
power supply, must be grounded. If this is not done the E3S-C may
malfunction, due to the switching noise of the power supply.
If an inverter motor or servomotor is used with the E3S-C, the frame
ground (FG) terminal and the ground (G) terminal, on the motor,
must be grounded, otherwise the E3S-C may malfunction.
J WATER RESISTANCE
To ensure the water resistance of the E3S-C, tighten the screws of
the operation panel cover to a torque of 3.5 to 5.5 kgf S cm (0.34 N S
m to 0.54 N S m).
Installation
J MOUNTING
Use M4 screws to mount the E3S-C. The tightening torque of each
screw must be 12 kgf S m (1.18 N S m) maximum.
J DIRECT MOUNTING
Mount the E3S-C as shown in the following illustrations.

J OPTICAL AXIS OF THROUGH-BEAM
SENSOR
The E3S-C through-beam models incorporate two lenses, one of
which will be used as shown in the following illustration. When using
a slit, the slit must be on the side where the lens is located.
