• The effective region corresponds to the ribbon connecting transmitter, reflector and receiver.
• The core region contains sufficient radiation energy to operate the system.
• The energy in the scattered region is not sufficient to ensure reliable operation of the system.

Alignment Possibilitites
The infrared beam can be adjusted by 10° increments horizontally and in 5° increments vertically from
the center axis. When selecting the optimum mounting location, remember that this adjustment range
can be fully used. Experience has shown that the detector and reflector should be arranged as parallel
as possible especially with distances of >162.5 feet, as this makes adjustment simpler.
