Retroreflectors
from Eaton’s electrical business are
used with reflex-type sensors. Two
types of retroreflective target mate­rial are available: corner cube and
embedded glass bead.

Corner Cube Retroreflectors

This type provides the highest signal
return to the sensor, typically 2000 to
3000 times the reflectivity of white
paper. Three adjoining sides are
arranged at right angles to each other.
When a ray of light strikes one of these
sides (A), it is reflected to the second
(B), then the third (C), and then back to
the source parallel to its original
course. Thousands of these cube
shapes are molded into a rugged plas­tic reflector or vinyl tape material.
Corner cube retroreflectors are suitable
for use with both standard reflex and
polarized reflex sensors.

Glass Bead Retroreflectors

Glass bead retroreflectors are avail­able in tape form with an adhesive
backing. The bead style surface is
typically rated at 200 to 900 times
the reflectivity of white paper —
much lower than corner cube reflec­tors. Glass bead retroreflectors are
not
reflex sensors.

Retroreflector Size

The size of the retroreflective target
has a significant effect on the excess
gain and range of a reflex sensor. In
general, we recommend you use the
largest possible reflector in every
reflex sensing application to maximize
performance of the sensor and
simplify alignment. To provide an
even larger reflective area, multiple
retroreflectors can be grouped
together as shown.

Using Retroreflectors with
Polarized Reflex Sensors

Only corner cube retroreflective
material can be used with polarized
reflex sensors. When polarized light
from the sensor’s light source strikes
a corner cube retroreflector, it is
returned to the sensor in a depolar­ized state. This allows some of the
light to pass through the detector’s
polarizer, which is positioned at 90°
to the source polarizer, to allow the
sensor to operate.

Glass bead retroreflectors do not
depolarize light and will not work
with polarized reflex sensors.

Molded plastic corner cube retrore­flectors are always recommended as
they provide the highest signal
return to the sensor.

Corner cube tape works with
polarized reflex sensors but returns
less light to the sensor. In all cases,
Eaton recommends testing sensor
and tape prior to final installation.
