3. Sensing range (referred to the standard target)
Nominal sensing range Sn
= characteristic value of the unit
Real sensing range Sr
= individual deviation at room temperature between 90% and 110%
of Sn
Useful sensing range Su
= switch point drift between 90% (Sumin = Sa) and 110% (Sumax)
of Sr
Safe sensing range =
operating distance Sa
= reliably switched between 0% and 81% of Sn
Safe switch-off distance
= Sumax + max. hysteresis = 143% of Sn
4. Correction factors
5. Influence of the standard target size
The sensor-specific values can be
found in the data sheet (exception
K1 units:
Same sensing range for all
X axis: Ratio between actual
target and the standard
target
