ADJUSTMENT
Analog
inductive sensors are equipped with a 20-turn spindle
potentiometer. This allows adjustment of anapplication specific operating range between the minimum distance “0 mm” and the type-typical maximum
value. Consequently, the full output current range (4...20 mA) is always present, regardless of the required
measuring distance. The analog sensors of series 10 are designed with a 2-colour LED that facilitates
adjustment. Outside the operating range I
A < 4 mA and I
A > 20 mA green light is emitted to display opera-tional readiness. Within the operating range of 4...20 mA the LED is yellow. In the undamped state the
output current value is > 20 mA and moves with the reduction of the object distance toward 4 mA (value at
total
damping approx. 2.5 mA).The data of the nominal sensing distance are based on the measuring method according to DIN VDE0660, Part 208. The respective nominal sensing distance is indicated with a tolerance of + 10 %. Thestandard measurement plate is square with a thickness of 1 mm and is made of carbon steel FE 360
(defined in ISO 630: 1980 ) with a smoothed surface and earthed. The side lengths are equal to the
diameter of the active area of the IAS or equal to 3 x Sn, depending on which value is greater. With a
different material or a smaller surface of the actuating element, the sensing distance is smaller
Sensing distance Adjustment of the sensing
distance of the inductive
analogue sensors is made by
means of a spindle potentiometer
with the screwdriver provided.For size M30x1.5 / ∅ 30:First open plastic tab.
For size > M30x1.5 / ∅ 30:First remove
plastic sealing screw. Typical response-time characteristic The possible sensing distance on a particular metal can be worked out by means of the typical reductionfactors: Sensing distance = S
n x reduction factor .
