Maximum expected deviation of the measurement value between the de-
termined and real distance value within the specified measurement range.
Smallest representable change in measurement value, distance and
speed.
Time the sensor needs in order to reach the operating temperature. An op-
timal measurement is only possible after the end of the warmup time.
The warmup time is approximately 20 minutes.
The output resolution describes how the measurement values are pre-
sented on the display and digital interfaces.
The output resolution of the ODS 10 is 1 mm and cannot be changed.
The delay before start-up indicates the point in time when the first valid
measurement can be obtained after switching on.
The behavior of the switching output if an object is within the taught/config-
ured switching distance.
• Light switching: switching output active (high)
• Dark switching: switching output not active (low)
Also integration time or measurement time. Maximum length of time from
the occurrence of an erratic change in distance to the steady state of the
measurement value.
The response time depends on the set average calculation. Although the
average calculation increases the response time, it also improves repro-
ducibility.
Time interval of measurement value updating at the interface.
Data memory of the connected IO-Link master.
Data Storage Upload.
Upload to the data memory of the connected IO-Link master.
Return and/or degree of reflection of the radiated light. In the case of sen-
sors with the time-of-flight measurement principle, the measurement range
depends on the reflectance.
Observe the specifications regarding diffuse reflection (see chapter 12
"Technical data").
• 90 % is white
• 6 % is black
Distance measurement procedures that determines the distance of an ob-
ject via the propagation time of a light pulse emitted by the sensor's trans-
mitter that is reflected by the object and received by the sensor's receiver.
Also repeatability. Deviation of multiple measurement results relative to
each other under identical conditions. Dependent on the measurement dis-
tance and the diffuse reflection of the measurement object.
The reproducibility can be considered as the measure of measurement
value noise and is affected by the configuration of the response time.
