BA Series
Operation Mode
If the control output terminal is short-circuit or over current than the rated current flows the unit, the sensor does not
operate normally by protection circuit.

Mounting And Sensitivity Adjustment
Install the sensor to the desired place and check the connections.
Supply the power to the sensor and adjust the optical axis and the sensitivity as follow ;
● Optical axis adjustment
Mount this unit at the center where the stability indicator
turns ON with moving the unit toward right or left, up or
down.

● Adjustment
1. When sensing the object, set the sensitivity adjuster in
stable Light ON area (orange: Light ON, green: Dark
ON) as shown '
2. The sensitivity should be adjusted depending on a
sensing target or mounting place.
ⓑ
3. Set the target at a position to be detected by the beam,
then turn the sensitivity adjuster until position ⓐ where
the operation indicator turns ON from min. position of the
sensitivity adjuster
4. Take the target out of the sensing area, then turn the
sensitivity adjuster until position ⓑ where the operation
indicator turns ON. If the indicator dose not turn ON,
max. position is ⓑ.
5. Set the sensitivity adjuster at the center of two switching
position ⓐ, ⓑ.
※ The sensing distance indicated on specification chart is
for 200×200mm of non-glossy white paper. Be sure that
it can be different by size, surface and gloss of target.
