It is thus important to position the safety light curtain according to
the minimum distance from any reflecting surface.
The minimum distance depends on:
Operating distance between emitter (TX) and receiver (RX);
Maximum opening angle of the light beam sent by the safety
light curtain, depending on the type of the device; in particular:
- 5° for ESPE Type 4 (± 2.5° as to the optic axis);
The graphic in Fig.8 shows the data of the minimum distance.
