Distances Between Identical Light Curtains - Pilz PSEN op4F/H-A Series Operating Manual

OPERATING MANUAL
This minimum distance depends on the following factors:
• The distance between the transmitter (TX) and receiver (RX)
• The actual opening angle of the light curtain; in particular:
The illustration in Fig. 10 shows the minimum distance from the reflective surface (D

Distances between identical light curtains

Should it be necessary to install several protective devices in adjacent areas, care must be
taken to ensure that the transmitter on one of the pairs does not dangerously interfere with
the receiver on another pair.
The interfering transmitter, TX B, must be installed outside the minimum distance D
the TX A - RX A axis of the transmitter/receiver pair.
This minimum distance D
• The distance between the transmitter (TX A) and receiver (RX A);
• The actual opening angle of the light curtain.
