Keep the following important characteristics of target reflection
in mind, when using the photocell:
Honeywell recommends using the retro-reflective target
supplied in the kit, with the photocell. This retro-reflective
target is unique because it reflects light back to its
illuminating source. On close examination, the target
consists of thousands of small glass beads or prisms held on
an adhesive backing held in place on the rotating component
with adhesive.
The Honeywell targets are only retro-reflective if the glass
beads are left exposed. Coating the glass beads with any
clear sealer destroys the retro-reflective quality of the target.
The user can use corner-cube retro-reflective tape. The user
can identify this type of tape by a chain-link pattern on the
surface, and a glossy surface finish.
The use of reflective tapes is not recommended. Reflective
tapes have very narrow return angles and must be mounted
in such a way that allows the background reflection to
adversely affect the gain of the photocell.
Other retro-reflective tapes are similarly not recommended
unless they are the same material as the Honeywell retro-
reflective targets.
