Sensors
SA1J : Full Color Recognition
Operation LEDs:
The operation LEDs (yellow) are on when the control out-
put is on.
Reference color set button:
With the reference color selector dial set to A
and with the sensor is aimed at color target A, press this button to memorize
color A. Repeat this procedure to memorize reference colors B and C.
Reference colors can also be registered by inputting an external signal using
the set input wire (SET) and the external input wire (EXT). (Refer to
Remote
Reference Color Registration on the following page.) Existing reference col-
ors are replaced by new reference colors.
Operation mode dial/reference color selector dial:
Normal run mode (tolerance 1 to 5):
Turn the dial to program one of
ve different degrees of sensitivity . Set the dial to 1 to distinguish the
slightest variation in reference color (narrow range of tolerance). Set the
dial to 5 to tolerate considerable variations in the reference color (wide
range of tolerance).
Select run mode (S RUN):
This mode allows the sensor to dene the
best tolerance. (No need to set tolerance.) Low tolerance is used to distin-
guish shades of color that are similar to the reference color. High toler-
ance is used to distinguish shades of color that vary from the reference
color. The output corresponds to the reference color that is most similar to
the object detected.
Reference color selector (SET):
This dial selects the reference color (A, B,
or C) for the reference color registration.
Inspection mode switches:
Color only (C):
Color only is used to inspect on the basis of color alone,
when surrounding lights inuence intensity , or when the inspection spot
varies.
Color plus intensity (C+I):
Color plus intensity is used to inspect on the
basis of color and depth of color when necessary to distinguish between
slight variations in shade.
Synchronous mode switch:
Select external or internal.
External synchronous mode (EXT):
External (EXT) is used to synchro-
nize inspection with an external signal.

Internal synchronous mode (INT):
Internal (INT) is used to perform inspec-
tions continuously corresponding to the response mode selection. Internal
response is activated when INT is selected and the reference color set button
is pressed.
Response mode switches:
Fast response mode (F):
This mode is used for high-speed inspection.
Response time is 0.8ms.
Normal response mode (N):
This mode is used for normal inspection.
Response time is 1.5ms.
Slow response mode (S):
This mode is used for stable inspection.
Response time is 6ms.
Off-delay timer (T-ON/T-OFF) switch:
This mode is used to select the OFF-
delay timer. The timer will maintain the output for 40ms.
Using External Synchronization
Using Internal Synchronization
Operation at Power ON
The light source does not go on immediately when power is turned on. The
sensor contains a circuit to initially delay the output for two seconds. To
ensure stable sensing, run a test operation for approximately 15 minutes.
1. In the previous gur e, “t” represents the amount
of time the external synchronous signals should
remain on in response to the response mode.
F (fast response): 0.5ms or more
N (normal response): 0.8ms or more
S (slow response): 3ms or more
2. To prevent chattering, use a non-contact output
sensor as the external synchronous input.
