 
Technical Information
Discover the technology of photoelectric sensors. Learn about
the components of a photoelectric system, the different sensing
modes, how to choose a system and how to use the system. Also
there is a helpful glossary for the beginner.
Thrubeam
Skan-A-Matic thrubeams deliver the most positive sensing
signal. They consist of a separate light source and photodetector placed
on opposite sides of objects to be detected. Detection occurs when the
beam of light between them is broken by the object.
Reflective Sensors
Skan-A-Matic reflective scanners combine a light source and
photodetector within a single housing. Light is emitted by the source and
returned to the photodetector - either by reflecting off a target or a
special retroreflective surface.
Special Purpose Sensors
Skan-A-Matic special purpose sensors are custom designed for
those unique applications not covered by our standard line-up. We offer
skanners to detect liquid levels, colors and wafers for the semiconductor
industry. Some of our special purpose sensors are furnished with flexible
fiber optic probes to detect objects in inaccessible places. If you have a
special need, Skan-A-Matic can design the unit to meet your requirements.
Self-Contained Photoelectric Controls
Skan-A-Matic self-contained photoelectric controls combine
sensor and control in one package. This results in less installation
time, and lower cost for each sensing position. These sensors
also have superior immunity to electrical noise than a separate
sensor and control combination.
Controls
Skan-A-Matic controls allow designers the option of altering
the function of photoelectric scanners to suit the requirements
of each individual application. Our photoelectric controls offer
on/off time delay, and other logic circuitry for single and multiple
scanner operations. Our modular approach allows you to assemble
a specific photoelectric system customized to your particular applications.
Accessories
