Start of Measuring Range
For ILR2250 sensors, the start of the measuring range is placed in front of the sensor. The point of reference is the front
housing edge on the sensor housing.

Reflector Installation
The sensor measures the distance to moving and stationary objects:
-
In the range of 0.05 m ... 100 m for diffuse surfaces
-
Between 35 and 150 m onto reflectors (e.g. ILR-RF210, Scotchlight by 3M etc.)
The measurement laser can be used for alignment. When aligning the sensor, proceed as follows:
Position the sensor close to the reflector (for example < 1 m).
The visible point of light of the measurement laser should be in the center of the reflector.
Position the sensor at the furthest possible point from the reflector.
Check that the measurement laser is pointing at the center of the reflector and adjust if necessary.
The center of the spot must be in the center of the reflector over the entire measuring range.
Target (reflector) and sensor can only be tilted by at most 5° relative to one another.

The
Signal
LED indicates the reflection strength of a measurement. This LED generally lights up when a measurement
is started.
1) Reduced measurement accuracy and measurement frequency possible
2) For sensors with optional heating function
