Datalogic SG2 BASE Series - 2.2.2 Distance between homologous devices

SG2 BASE
21/68
Diagram of shows the minimum distance from the reflecting surface (Dsr), based on the operating distance:
Fig 13 - Minimum distance from reflective surface
The formula to get Dsr is the following:
For ESPE Type 2:
Dsr (m) = 0.27 for operating distance < 3 m
Dsr (m) = 0.5 x operating distance (m) x tg 2a for operating distance >= 3 m
