It is thus important to position the safety light curtain according to the
minimum distance from reflecting surfaces.
The minimum distance depends on:
• Operating distance between emitter (TX) and receiver (RX);
• Real opening angle of AOPD (EAA); in particular:
for AOPD type 2 EAA = 10° ( α = 5°)
Diagram of Fig. 8 shows the min. distance from the reflecting surface
(Dsr), based on the operating distance:
Fig. 8
The formula to get Dsr is the following:
Dsr
(m) = 0.27 for oper. distances < 3 m
D sr (m) = 0,5 operating distance (m) x tg 2 α for oper. distances ≥ 3
