What is the difference between photoelectric sensors and optical sensors?
ShaunMarshgp7659
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 are photoelectric sensors used for?
Photoelectric sensors use light to detect the presence, absence, or distance of an object. They often use the infrared spectrum of light, though visible light is also used.
What are optical sensors used for?
Optical sensors convert light, or changes in light, into electrical signals. They are used in products such as automatic lighting and flashes for cameras.
How does proximity sensor work?
Without physical contact detecting the presence of objects is the purpose of proximity sensors. They work based on inductive, magnetic, photoelectric and capacitive properties of objects.
What is the difference between sensor and a actuator?
sensors sense how things are running, to see if anything needs to be adjusted, send info to ECU, ECU then sends info to actuator then the actuators does something to deal with the problem... sensors - input, actuators - output.
What is the light source used in most industrial photoelectric sensors?
The light source is typically a diode that emits either visible or infrared light. Other photolelectric sensors use lasers, which emit more coherent beams that scatter less and maintain their brightness over a distance. (see also the related link)
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.
What are photoelectric sensors used for?
Photoelectric sensors use light to detect the presence, absence, or distance of an object. They often use the infrared spectrum of light, though visible light is also used.
What is the difference between optical and radio?
Optical telescopes use either lens' (refractory) or mirrors (reflective) to magnify light. Radio telescopes use dishes to pick up radio waves. sensors on the dishes collect the waves and turn them into a picture
What are optical sensors used for?
Optical sensors convert light, or changes in light, into electrical signals. They are used in products such as automatic lighting and flashes for cameras.
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.
What is applications of photoelectric effect in our daily life?
It is in the digital cameras, image sensors, and night vision devices that are widely used in the present world.
How can you tell the difference between a digital sensor and an analog sensor?
Analogue sensors are usualy more accurate :P

Where can I find good deals on used optical sensors?
You can find them at AMeds.com Look under health care.
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.
