Malfunctioning
If an inverter motor or servomotor is used with the E3S-CR67/62,
the frame ground (FG) terminal and the ground (G) terminal must
be grounded, or otherwise the E3S-CR67/62 may malfunction.

OPTICAL AXIS ADJUSTMENT
Direct the mounting axis of the mounting bracket in the direction
where sensing objects will be located. The optical axis of the
E3S-CR67/62 coincides with the mounting axis of the mounting
bracket, which enables the user to adjust the optical axis of the
E3S-CR67/62 with ease.
Optical Lock Holes
By tightening the optical axis lock holes with screws, the
mounting bracket will be in the direction of the optical axis of the
E3S-CR67/62.

Terms
• D.O.
See Dark Operate.
• Dark Operate
Operating mode where the output is turned on (transistor
becomes conducting, or relay coil is energized) when light is
NOT received.
• Excess Gain
See Stability Indicator.
• IEC
International Electrotechnical Commission.
• Interference Protection
See Mutual Interference Protection.
• IP
International Protection; an international standard scale for
enclosure ratings (sealing).
• IP66
Approximately NEMA 4, 4X, “heavy seas” test; the item is
subjected to a stream of water from a
1
/
2
”nozzlewith14psi
pressure at a distance of 1.5 meter. Water must not enter the
item.
• IP67
Approximately NEMA 6, “immersion” test; the item is
immersed under 1 meter of water for 30 minutes, with no
water entry.
• kgf  cm
Kilogram-force centimeters, measure of torque;
1kgf  cm = 10.4 in  lb.
• Lensed effect
Optical phenomenon where light passing through a
transparent object (bottle, for instance) is focused in the
same manner as a lens. If the lens effect is “converging,” the
light intensity may be increased significantly. When sensing
the presence of an object, due to the reduction of light
passing through that object, the lens effect may cause a
failure to detect the object. The light intensity may not be
reduced due to the “lens” effect of concentrating the light
beam.
• L.O.
See Light Operate.
• Light Operate
Operating mode where the output is turned on (transistor
conducts, or relay coil is energized) when light is received.
• Mutual Inference Protection
Circuitry that allows the sensor to detect and compensate for
interfering signals that may be emanating from sources within
its sensing range. The sensor can then operate normally,
ignoring the interfering signal(s).
• NEMA
National Electrical Manufacturer’s Association; industrial
trade organization that publishes testing standards, including
enclosure ratings.
• NPN
Transistor output designed to provide a path to ground for
current passing through the load (”sinking”). When the NPN
output is on, current can then pass from Positive, through the
load, and through the NPN transistor to ground, completing
the circuit.
• PNP
Transistor output that provides a path to “Plus” for current
passing through the load (”sourcing”). When the PNP output
is on, current can then pass from Positive, through the PNP
transistor, through the load, and to ground, completing the
circuit.
