Choose one of the two adjustment methods for setting the
LINEARITY adjuster. Adjustment of the 4 mA and
20 mA LINEARITY adjusters must be performed with the
standard target at positions of 20% and 100% of the rated
detecting distance away from the sensor.
Linearity Adjustment Method 1
1. Connect an ammeter across terminals 1 and 2. The
2. Place the standard target at 20% of the rated detecting
3. Turn the 4 mA LINEARITY adjuster slowly clockwise (to
4. Place the standard target at the rated detecting distance.
5. Turn the 20 mA LINEARITY adjuster slowly clockwise (to
6. To fine tune the adjustment accuracy of the output current,

decrease the output current). Set the adjuster to a position
that reads 4 mA output on the ammeter.

Linearity Adjustment Method 2
1. Set the standard target at 20% of the rated detecting
2. Turn the 4 mA LINEARITY adjuster counterclockwise so that
3. Set the standard target at the rated detecting distance away
4. Slowly turn the 20 mA LINEARITY adjuster clockwise until
Place the standard target at the specified position. If the target
moves in parallel with the surface of the sensor unit, make the
adjustment after determining the position using the following
procedure.
1. Adjust the linear output according to Adjustment Method 1
2. Calculate detecting distance X using the following formula:
3. Adjust the distance between the sensor and the object to
Slowly turn the SENSITIVITY adjuster clockwise (toward HIGH)
and stop turning when the OPER. indicator illuminates. Move
the target to confirm that the OPER. indicator illuminates when
the object to be detected is at the specified position and that
the indicator goes OFF when the target is moved away from
that position.
If the target moves in parallel with the surface of the sensor
unit, place the sensor at distance S.
