What is the difference between photoelectric sensors and optical sensors?
A photoelectric sensor, or photo eye, is a device used to detect the distance, absence, or presence of an object by using a light transmitter, often infrared, and a photoelectric receiver. They are used extensively in industrial manufacturing. There are three different functional types: opposed (through beam), retro-reflective, and proximity-sensing (diffused).Electro-optical sensors are electronic detectors that convert light, or a change in light, into an electronic signal. They are used in many industrial and consumer applications, for example: Lamps that turn on automatically in response to darkness. Position sensors that activate when an object interrupts a light beam.
What detects the presence or absence of a mark in a predetermined place?
A sensor or detector is typically used to detect the presence or absence of a mark in a predetermined place. These devices can use various technologies such as photoelectric sensors, proximity sensors, or vision systems to detect the mark accurately.
How position sensors work?
On the 3800, its a simple optical gate, that reads the teeth in a toothed wheel. If you crack open most ball-mice, they work on the same concept.
Are sensors are limited in some way either by design or by the type of energy they are designed to receive.?
Yes, sensors are limited by their design and the type of energy they are meant to detect. For example, optical sensors are limited by the wavelength of light they can detect, while temperature sensors are limited by their range and accuracy. Additionally, sensors may have limitations in terms of sensitivity, resolution, and environmental conditions in which they can operate effectively.
How do machines recognize paper money?
Machines recognize paper money using a combination of sensors, such as optical sensors for reading security features like watermarks and holograms, magnetic sensors for detecting magnetic inks, and infrared sensors to verify the presence of specific features. This information is then compared to a database of known currency features to authenticate the bill.
Where can I find good deals on used optical sensors?
You can find them at AMeds.com Look under health care.
What is the difference between a laptop wireless optical mouse and a wireless laser optical mouse?
The laser wireless optical mouse has laser sensors to direct the mouse on the screen as without it is a roll ball used to do so.
Can an optical mouse that uses optical sensors be placed on nearly all types of flat surfaces?
Yes you can

Where can I find information on optical sensors online?
There is a pretty well-populated list of optical sensor manufacturers at http://www.sensorsportal.com/HTML/SENSORS/OptoSens_Manufacturers.htm for starters. Also, another rather large list of manufacturers and suppliers is located here: http://www.thomasnet.com/products/optical-sensors-73749350-1.html. As for information on them, wisegeek.com has a good article on them here: "http://www.wisegeek.com/what-is-an-optical-sensor.htm" Hope this helps!

What are the main characteristics of microwave remote sensing and optical remote sensing?
Optical remote sensing is affected by cloud covers , rain etc but microwave remote sensing is not.However the optical sensors always need sun as a source of illumination while active microwave sensors don't need.

How do you separate things?
If this is a question concerning industry, there are various methods. With size as a sorting factor, wire mesh is often used or openings of various size. Optical sensors placed on a diverging conveyor with a pushing "arm" can be used to sort by color. High strength magnets can be used to sort magnetic materials from nonmagnetic. Hall effect sensors may also be used for this purpose, with the same diverging conveyor system that I mentioned with optical sensors. Different fluids can be separated by centrifuge, or by a distillation process. Particulates are separated from fluids by filtration. I hope this helps.

What is a opital mouse?
An optical mouse is a computer input device that uses a laser to sense the movement of your hand. The old style mouse used a ball with wheel sensors attached to it.
What is the function of sensor on PLC system?
Sensors send incoming signals either digital or analog to PLC. There are a lot of types of sensors: inductive, capacitive, temperature, optical, etc.
