*2. When teaching with/without a workpiece, the best sensing method will be
automatically selected (RGB ratio (C Mode) or light intensity determination
(I Mode)). If color differences are not strong enough and RGB ratios would
result in unstable detection, then light intensity determination (I Mode) will be
selected.
The detection mode can be set to C, I, or Black Mode.
*3. Input Specifications
Contact input
(relay or switch)
NPN
ON: Shorted to 0 V
(sourcing current: 1 mA
max.).
OFF: Open or shorted to Vcc.
Non-contact input
(transistor)
ON: 1.5 V max.
(sourcing current: 1 mA max.)
OFF: Vcc - 1.5 V to Vcc
(leakage current: 0.1 mA max.)
PNP
ON: Shorted to Vcc
(sinking current: 3 mA
max.).
OFF: Open or shorted to 0 V.
ON: Vcc - 1.5 V to Vcc
(sinking current: 3 mA max.)
OFF: 1.5 V max.
(leakage current: 0.1 mA max.)
*4. Mutual interference prevention cannot be used in super-high-speed mode,
and light intensity determination (I Mode) must be used. The response time
will be 150 μs if an AND or OR is set for the control outputs.
*5. With light intensity determination (I Mode and Black Mode), the correlation is
not displayed, but rather the light intensity is displayed.
*6. The allowable ambient operating temperature changes according to the
number of Units that are linked.
2 Units: −25 to 55°C, 3 to 10 Units: −25 to 50°C, and
11 to 16 Units: −25 to 45°C

Operating Procedures (Typical)
Detecting Marks
Detecting Black Marks
Because it distinguishes RGB
ratios, detection is highly resistant
to workpiece movement.
Distinguishing Trays
Through-beam heads are capable
of detecting color differences in
semi-transparent objects.
Detecting Wafers
In Black Mode, blank seam tape and
other black marks can be detected
regardless of film color or patterns
Detecting Products on Conveyors
Four-color determination greatly
reduces the work required for
line switchovers.
Workpieces that absorb a specific
wavelength can be detected with
a wide range of wavelengths.
If you teach the conveyor (i.e., the
background), you can detect
workpieces even if they have
different colors, shapes, or gloss.
