Sick Sensors – the principle and practical application of color mark sensors
Principle:
Contrast sensors are often used to detect spots on specific color marks or objects, and they are used to detect color marks by comparing them to non-color mark areas, rather than directly measuring color. The color mark sensor is actually a reverse device, where the light source is mounted perpendicular to the target object, and the receiver is connected to the ...

Sick Sensors – Where can ultrasonic sensors not be used?
(1) When the target to be measured is not perpendicular to the transducer of the sensor. This is because the target of the ultrasonic test must be within an angle of no more than 10° perpendicular to the sensor.
(2) When a small beam diameter is required. Because the diameter of the general ultrasonic beam is ...

An introduction to the three common types of photoelectric sensors
1. Photoelectric switch sensor
The occlusion between the transmitter and receiver is used to detect states such as motion, object presence, or object position. When the measured object passes through the occlusion beam, the intensity of the light signal received by the receiving head changes, which in turn triggers the switching signal. Photoelectric switch ...

Sick Sensor – The difference between an infrared sensor and a laser sensor
Infrared sensors: Sensors that take advantage of the physical properties of infrared rays to make measurements. Infrared light is also known as infrared light. The infrared sensor does not have direct contact with the measured object during measurement, and the anti-interference performance is poor, so the lens needs to filter the infrared light before measurement, and it needs to be calibrated regularly.

Sick Sensors – The system composition of ultrasonic sensors
Transmitter: An oscillator (usually ceramic, about 15 mm in diameter) vibrates to generate ultrasonic waves and radiate them into the air.
Receiver: When the oscillator receives the ultrasonic wave, it generates the corresponding mechanical vibration according to the ultrasonic wave and converts it into electrical energy as the output of the receiver.

Sick sensors – how light-sensitive sensors work, classification and areas of application
A photosensor is a sensitive device that responds to or converts external light signals or light radiation. A photosensor is a sensor that uses a photosensitive element (photodiode) to convert an optical signal into an electrical signal. Their sensitive wavelengths are close to those of visible light, including infrared and ultraviolet wavelengths ...

Sick Sensors – An introduction to the photoelectric effect of photoelectric sensors
It is a physical phenomenon in which light irradiates certain substances and changes the conductive properties of the substance, which can be divided into three categories: external photoelectric effect, internal photoelectric effect and photogenerated volt effect. The external photoelectric effect refers to the physical emission of electrons from the surface of an object under the action of light.
