Clear-object photoelectric sensors detect presence when a clear object interrupts light rebounding off a fixed reflector (sold separately) or when used as part of a through-beam pair. These sensors use infrared visible, red light or UV light sources and offer detection ranges up to 4.2 meters.
Clear-object photoelectric sensors have the ability to detect objects that are transparent or semi-transparent. These sensors are available in
AC- or DC-powered models to meet application needs, and offer detection ranges up to 4.2 meters.

For applications with thicker or larger transparent objects, the sensors use polarized red light
Versions with patented UV light technology take advantage of the fact that transparent materials absorb
large amounts of polarized UV light, making it easy to set the threshold at which these sensors switch
UV sensors require C23 TRU series reflectors (sold separately)
