Proximity Switch Sensor Adjustment
All capacitive switches have a potentiometer which allows switch sensitivity to be adjusted for the best
results. To establish the proper sensitivity for a particular set of target conditions, follow these procedures.
1. Mount the switch in the application. Set up the worst case condition which can cause a false “OFF”
signal. As an example, assume the switch is being used to sense the level of a liquid through a sight
glass. The worst case condition exists when moisture is present on the inside surface of the glass.
Turn the potentiometer clockwise (CW) until the LED is OFF, then turn the potentiometer
counterclockwise (CCW) until it just turns ON.
2. Bring the target into position. In the example, bring the water above the level of the switch. The LED
should be OFF. Turn the potentiometer CCW and count the number of turns until the LED turns ON.
3. Turn the potentiometer CW for half the number of turns counted in
. For example if it took
four (4) turns for the LED to turn ON, turn the potentiometer two (2) turns CW. The switch will now
be set.
