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 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 maximum Sensing frequency of photoelectric sensors?
The maximum sensing frequency of photoelectric sensors can vary depending on the specific model and manufacturer. However, typical sensing frequencies can range from a few hundred Hz to several kHz. It is important to check the datasheet or specifications of the sensor to determine its maximum sensing frequency.
How traffic signals use photoelectric effect?
Traffic signals use photoelectric sensors to detect the presence of vehicles at intersections. These sensors emit a beam of light, and when a vehicle passes through the beam, it blocks the light, triggering the signal to change. This system enables traffic signals to efficiently control the flow of traffic at junctions.
What element is used in photoelectric?
The element commonly used in photoelectric cells is silicon. Silicon is a semiconductor material that can absorb photons of light and generate an electric current.

Is rubidium used in photoelectric cells?
Well, honey, rubidium might be feeling a bit left out because it's not the star of the show in photoelectric cells. While it can be used in some specialized cases, it's not exactly the go-to choice for most photoelectric cell applications. So, in short, yes, rubidium can be used in photoelectric cells, but it's not exactly stealing the spotlight.

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.

What is photoelectric imaging how is it done?
Photoelectric imaging is a process that converts light into an electric signal for capturing visual images. It is typically done using sensors or detectors that respond to light by generating an electrical current proportional to the intensity of the light. This electrical signal is then processed to create a digital image.
