Sensors
SA1J : Full Color Recognition
.
Installation Requirements
Install the sensor so that distance “a” between the lens and
the object complies with the values shown in the table above.
Tilt the optical axis by approximately 15˚ to the vertical direc-
tion of the object surface.
Position the spot center away from the mounting hole. Refer
to the horizontal distance represented by “c.”
Determine the best installation position to ensure stable
sensing. (Refer to the table above.) The best installation posi-
tion depends on the object to be detected.
Figure 1 illustrates the correct way to install the SA1J. The
sensing direction in Figure 1 is less affected by changes in
the sensing angle than the sensing direction in Figure 2. The
sensor should be oriented so that the object moves in the
direction shown in Figure 3.

Do not use the sensor in extremely dusty areas or areas sub-
ject to strong shocks or vibrations. In addition, do not use the
sensor near the following:
• Induction machines and heat sources
• Oil and chemicals
• Corrosive gasses
• Water (for a long period of time)
Do not expose the receiver to excessive extraneous light.
Use a soft cloth dipped in alcohol to remove dust from the
sensing area on the front of the sensor. To avoid damaging
the sensor, do not use organic solvents for cleaning.
To avoid damaging the sensor, do not tighten the mounting
screws excessively. The maximum tightening torque for the
mounting screws should be less than 2.0N·m.
Do not apply excess voltage between the power supply and
the housing.
When installing SA1J sensors in parallel, maintain at least
30mm spacing between units.
When closing the cover, the tightening torque should range
from 0.49N·m to 0.69N·m. Do not allow dust to accumulate
inside the operation cover, because the degree of protection
(IP67) may be impaired.
The turning torque for the inspection tolerance dial should
not exceed 0.02N·m.
The operating force for the reference color set button should
not exceed 30N.
Installation
Connect wiring according to the diagrams on the following
page. Miswiring will cause damage.
The power voltage should not exceed the rated range.
Do not install high-voltage and power lines in the same con-
duit as the input and output lines. Use separate conduits.
If wires are long, power lines and electromagnetic equipment
may interfere with the sensor’s operations. Use a separate
conduit for wiring.
When using a switching power supply, be sure to ground the
FG (frame ground) terminal.
Cable extension is allowed up to 100m using a cabtyre cable
with core wires of 22 AWG or more.
