The Cutler-Hammer® Comet Series is a
complete line of high performance, 18 mm
tubular sensors with a variety of models and
modes to solve virtually any sensing problem.
The sensors are available in thrubeam,reflex,
polarized reflex, diffuse reflective, focused
diffuse reflective, wide angle diffuse reflective,
Perfect Prox®, fine spot Perfect Prox and fiber
optic sensing.
Perfect Prox is one of the most powerful
problem-solving sensors available. These
sensors can reliably detect targets of different
color, reflectance, contrast or surface shape
at the same range, while ignoring background
objects just a fraction of an inch away.
The Comet Series includes AC/DC and
DC-only models with, 3- and 4-wire circuitry.
Choose from cable or microconnector.
Each sensor features a light/dark operation
switch and a gain control to provide for
quick adjustment to peak optical
performance. The unique threaded body with
flat sides allows quick mounting in a 3.4" hole
or against any flat surface. Internal
components are rigidly sealed in a solid
encapsulated package for excellent
performance in high vibration and highshock
applications.

NEMA test specifications.
SENSING MODES
Thru-Beam
Separate light source and detector units face
one another across an area. The column of
light traveling in a straight line between the
two lenses is the effective sensing beam. An
object crossing the path has to completely
block the beam to be detected.
Polarized Reflex
The source and detector are positioned
parallel to each other on the same side of the
object to be detected. Another element,
called a retroreflector, is placed across from
the source and detector. The sensing beam
is reflected from a retroreflector back to the
sensor. The Comet Series includes polarized
models with 3-wire and 4-wire circuits.
Right-angle models are also available.
Models feature a polarizing filter built into
the sensor to ensure that only light reflected
from a corner-cube retrore-flector is
recognized by the sensor. This allows
reliable detection of shiny targets that could
reflect light and be missed by a nonpolarized
sensor. Most models include a
visible sensing beam for easy installation
and alignment.
Diffuse Reflective
The source and detector are positioned on
the same side of the target. The two
components are aligned so that their fields
of view cross. When the target moves into
the area, light from the source is reflected off
the target surface back to the detector. A
retroreflector is not required. Forward and
right-angle viewing configurations offer
identical optical performance in this series.
Perfect Prox®
This is a unique type of diffuse reflective
sensor that combines extremely high
sensing power (called “excess gain”) with a
sharp optical cutoff to ignore backgrounds.
This allows the sensor to reliably detect
targets regardless of variations in color,
reflectance, contrast or surface shape, while
ignoring objects that are just slightly outside
the target range. This gives the Perfect Prox®
an outstanding ability to solve sensing
applications that would be difficult or
impossible to manage with other types of
sensors. It also makes Perfect Prox® one of
the easiest photoelectric sensors to set up
and use.
Eaton’s Comet Series includes more
background rejection models than any other
family on the market. Choose from forward
or right-angle viewing, 3- or 4-wire circuits,
cable, micro or mini-connector terminations
and a variety of sensing ranges.
Fiber Optic
The Comet Series also includes sensors that
utilize fiber optic cables to sense objects
where space is restricted, temperatures are
high, or tight viewing angles are required.
Choose from models that accept low cost
plastic fiber optic cables, or use our patented
glass fiber optic adapter that inexpensively
converts our standard diffuse reflective
sensors for use with durable glass fiber optic
cables.
Mounting
Comet Series sensors feature a threaded
housing and include two jam nuts and
washers for mounting into any
19 mm (0.75") hole or a selection of
accessory mounting brackets available from
Eaton. The flat sides of the sensor feature
two mounting holes for easily attaching the
sensor to any flat surface with #4 hardware.

Note: (1)For a complete system order one source and one detector; 11100 sources and 12100 detectors may be interchanged in any combination. 11102 models must be used with 12102 models.
(2) Ranges based on 3 inch diameter retroreflector. (3) Right-angle viewing polarized reflex models are rated NEMA 1 only. (4) Polarized Reflex Sensors may not operate with retroreflective tape. Test selected tape prior to installation. (5) For complete system, order sensor and retroreflector.
(6) Sensor will detect a 90% reflective white card at this range.
(7) Sensor will detect a 90% reflective white card at this range.
Ordering Example: (1) 11102AQD03 Thru beam source with a 4-pin ac micro cable, $144.00, plus (1) 12102AQD03 Thru beam detector with a 4-pin ac micro cable, $195.00, $144.00 + 195.00 = $339.00
