Terms
Color Registration
Detection of a special mark on packaging material referred to
as the Registration Mark. This mark is aligned with the
printed pattern on the wrapping material and allows proper
cut-off of the packaging material so that printed images
appear in the correct location on the package.
Conformity/Non-conformity
In the E3MC Color Sensor, term used to indicate when the
target color matches a reference color stored in the memory
bank(s). A match is “conformity,” and a mismatch is
“non-conformity.”
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. In the E3MC Color Sensor, this refers to the
mode where the output turns on when the target color does
NOT match (non-conformity) the reference color stored in the
memory bank.
Diffuse Reflective
Sensor configuration with the emitter and receiver located in
the same housing. Sensing of target is based on reflection of
light from the target itself (rather than a retroreflector).
Excess Gain
See Stability Indicator.
External Synchronous Input
In the E3MC Color Sensor, an input that allows “l(fā)atching” of
the output when the input is taken high, preventing a change
of state until the input is taken low.
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
” nozzle with 14psi
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
Kilogram Force.
kgf
cm
Kilogram-force centimeters, measure of torque;
1 kgf
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 attenuation 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 “l(fā)ens” 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. In
the E3MC Color Sensor, refers to the mode where the output
turns on when the target color matches (conforms) to the
reference color stored in the memory bank.
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. Sensor can then operate normally, ignoring
the interfering signal(s).
nm
Nanometer; a measure of length, 10
--9
meters, 3.937 x 10
--8
inches.
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.
Reflective Mode
See Diffuse Reflective.
Response time
Elapsed time from when a target moves into the sensing
zone of a sensor to when the output turns on. May also refer
to the “turn-off” time. The sum of turn-on and turn-off time is
the total cycle time (reciprocal of switching frequency, Hz).
Reverse Polarity Protection
Circuitry that prevents damage to the device if power is
incorrectly connected (polarity reversed, DC). The unit may
not work while polarity is reversed, but is undamaged, and
will work once polarity is corrected.
