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.
Laser: The radiation produced by the stimulation of light at 1.65um amplified by amplification. Laser Sensor: A sensor that utilizes laser technology to make measurements. It consists of a laser, a laser detector, and a measurement circuit. Its advantages are that it can achieve non-contact long-distance measurement, fast speed, high accuracy, large range, strong anti-optical and electrical interference ability, etc.
Infrared sensors consist of an optical system, a detection element, and a conversion circuit. Optical systems can be divided into two categories: transmissive and reflective according to different structures. According to the working principle, the detection element can be divided into thermal detection element and photoelectric detection element. The most widely used thermistors are thermistors. When the thermistor is exposed to infrared radiation, the temperature rises, the resistance changes, and the conversion circuit becomes an electrical signal output. Photoelectric detection elements are commonly used photosensitive elements, which are usually made of lead sulfide, lead selenide, indium arsenide, antimony arsenide, mercury cadmium telluride ternary alloy, germanium and silicon doped materials.
When the laser sensor works, the laser emitting diode is first aimed at the target to emit a laser pulse. It is received by the optical system and imaged onto an avalanche photodiode. An avalanche photodiode is an optical sensor with an internal amplification function, so it can detect extremely weak optical signals and convert them into corresponding electrical signals. This system is characterized by high measurement accuracy, high stability, and is not affected by other interfering factors.

Sick Sensors – What are the Common Types of Proximity Sensors?
Capacitance – As the name suggests, these sensors work by recording changes in capacitance, which is a function of charge and voltage between two surfaces with an air gap or other material known as the dielectric constant. When the object to be measured enters the sensor field, it has an impact on the medium.

Sick sensors – how to work and how to use color mark sensors
How the color mark sensor works
The color mark sensor is actually a reverse installation, the light source is perpendicular to the target object device, and the bearer is biased towards the device at an acute angle to the object, so that it only detects the scattered light from the target object, and then prevents the sensor from directly bearing the reflected light, and can make ...

Sick Sensors – Troubleshooting Methods for Photoelectric Sensors
1. The pressure goes up, the output of the transmitter does not go up to this situation, you should first check whether the pressure interface is leaking or blocked, if you admit that it is not, check the wiring method and check the power supply, if the power supply is normal, then simply pressurize to see if the output changes, maybe observe whether the zero position of the sensor has an output, if there is no ...
