PSEN op4B Series Operating Manual

So, when installing the device close to reflective surfaces (metal walls,
floors, ceilings or workpieces), it is vital that the minimum distance in
relation to reflective surfaces is maintained, as shown in the diagram in
Fig. 8. This minimum distance depends on:
• The range between the emitter (TX) and receiver (RX)
• The maximum open angle of the light beams transmitted by the
emitter (TX):
5° for Type 4 ESPE (± 2.5° to light axis)
The values for the minimum distance in relation to the operating range
can be taken from the illustration in Fig. 8.
