Procedure Turn the sensitivity adjuster from minimum to
maximum and set the sensitivity adjuster to the
position where a stable condition can be obtained.
If the sensing object is larger than the reflector
diameter, set the sensitivity adjuster to maximum.
If the sensing object is the same or smaller than
the lens diameter, turn the sensitivity adjuster from
minimum to maximum to set the sensitivity adjuster
to the position where a stable condition can be
obtained.
Precautions

CONNECTION
If the input/output lines of the Clear Material Sensor are placed in
the same conduit or duct as power lines or high-voltage lines, the
Clear Material Sensor may malfunction, or be damaged by
electrical noise. Either separate the wiring, or use shielded lines
as input/output lines to the Clear Material Sensor.
The cord connected to the E3S-CR67/62 can be extended up to
100 m provided that the diameter of each wire of the cord is
0.3 mm
2
minimum.

STARTUP OPERATION
A maximum of 100 ms is required from the time power is turned
on until the E3S-CR67/62 is able to detect objects. If power is
supplied to the loads and the E3S-CR67/62 from different
sources, turn on power to the E3S-CR67/62 first.

POWER SUPPLY
If a standard switching regulator is used as a power supply, the
frame ground (FG) terminal and the ground (G) terminal must be
grounded, or otherwise the E3S-CR67/62 may malfunction, due
to the switching noise of the power supply.

WATER RESISTANCE
Do not use the E3S-CR67/62 in water, in the rain, or outdoors.
To ensure the water resistivity of the E3S-CR67/62, tighten the
screws of the operation panel cover to a torque of 3.5 to 5.5 kgf 
cm (36.4 to 60.2 in  lb).

OIL AND CHEMICAL RESISTANCE
Do not use the E3S-CR67/62 in oils or liquid chemicals.

CABLE
The E3S-CR67/62 uses an oil-resistive cord to ensure oil
resistance.
Do not allow the cable to be repeatedly bent during application.
Do not allow the cable to be bent to a radius of less than 25 mm.

MOUNTING
When mounting the E3S-CR67/62, avoid heavy impact (see
shock and vibration specifications) which may damage sensor.
Use M4 screws to mount the E3S-CR67/62.
The tightening torque of each screw must be 12 kgf  m
(124 in  lb) maximum.
Mounting Bracket
When mounting the E3S-CR67/62 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-CR67/62 so that the sensing
objects will be in the direction the mechanical axis, move the
E3S-CR67/62 upwards, downwards, to the left, or to the right and
secure the E3S-CR67/62 in the center of the range where the
light indicator will be lit, at which time make sure that the stability
indicator is lit.
