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.
