Table Sampling Rate / Accuracy / Repeatability - IFM Electronic EFECTOR PMD O1D100 Bedienungsanleitung

Hysteresis function:
The hysteresis is calculated from the repeatability (see table below)
with a safety factor 1.5.
Example: Sampling rate 50 Hz, distance to the object 1200 mm, grey value
(18 % remission):
Repeatability according to the table 20 mm x factor 1.5 = 30 mm
→ Reset point 1200 mm + (30 mm / 2) = 1215 mm
→ Set point 1200 mm - (30 mm / 2) = 1185 mm
The reset point is always greater than the set point.
For sensing ranges up to 6000 mm the hysteresis is calculated for a
18 % remission, for sensing ranges over 6000 mm for a 90 %
remission.
Table for sampling rate 50 Hz:
Distance [mm]
200...1000
1000...2000
2000...4000
4000...6000
6000...10000
Range on black (6 % remission) ≥ 4000 mm
The values apply at
- constant ambient conditions (23° C / 960 hPa)
- extraneous light of max. 8 klx
- only after unit powered up for 10 minutes.
