Q: What is Industry 4.0

D：In order to take the lead in the new round of industrial revolution and compete for the voice of international industrial competition, Germany implemented the Industry 4.0 strategy, while the United States promoted the concept of the Industrial Internet. The basic concepts of the two are similar, both are virtual networks and entities connected, which is an exploration of the future development direction and development model of industry.

Industry 4.0 refers to the transformation of production or service models from centralized control to decentralized enhanced control, helping to achieve highly flexible personalized and digital production or services.

Industrial Internet pays more attention to software, network and big data, aiming to realize the integration of communication, control and computing.

Q: Definition of Industrial Safety Light Curtain

D：The light curtain product, manufactured strictly in accordance with relevant standards and used for human safety protection in industrial environments, with complete internal self inspection and rectangular area scanning monitoring, is called a safety light curtain.
Installing safety light curtains in certain hazardous areas can effectively reduce risks and prevent accidents from occurring!

Q: Definition of standard test substance

D：The sensing distance of proximity sensors varies depending on the size and material of the detection object, and as the shape of the detection object increases, the sensing distance lengthens. When the volume reaches a certain value, the sensing distance no longer increases with the shape of the detection object and becomes a fixed value. The minimum detection object that reaches a fixed sensing distance is usually referred to as the standard detection object.

The standard test object is generally made of iron, with a thickness of 1mm in a square shape, and the side length is taken as the larger of the diameter of the sensing surface and three times the sensing distance.

Q: How to determine the actual detection distance of the proximity sensor?

D：① Reference standard detection distance (when the tested object is different from the standard detection object, the actual detection distance may not necessarily be the detection distance on the sample)
② Determine the main factors that affect the detection distance: 1. The size and material of the object being detected; 2. Detecting the thickness of objects; 3. Diameter of the sensor
③ View the sample and determine the actual detection distance

Q: What are the general types of light sources for photoelectric sensors

D：The emitter of photoelectric sensors usually uses the following types of light sources:

Red LED - visible light, easy to adjust.

Infrared LED - high-energy invisible light.

Red laser - visible light

Its physical properties make it an ideal choice for small object detection and wide range detection.

Q: What issues should be noted during the use of sensors

D：Firstly, it is necessary to confirm the correct wiring method and supply a stable rated voltage. Then, when installing the sensor, it is necessary to consider its own characteristics.

For example, when installing inductive sensors, attention should be paid to interference issues to ensure that the distance between adjacent sensors is not too close. In some cases, shielded sensors can be chosen as much as possible to achieve relatively good anti-interference effects.

Q: What should be noted when selecting sensors

D：In terms of parameters, it is mainly necessary to determine the product's appearance and dimensions, detection distance, working voltage, output mode (NPN/PNP), and output form (normally open/normally closed),

At the same time, it is also necessary to ensure the accuracy of parameters such as the sensor's wiring form (direct wiring/plug-in type), cable length, frequency requirements, environmental temperature requirements, waterproof and dustproof requirements (IP level), etc.

In addition, if there are special testing requirements, it is necessary to choose a special type of sensor. Taking inductive sensors as an example, a variety of sensor products with special requirements such as high voltage resistance, high temperature resistance, high frequency, strong magnetic immunity, analog output, explosion-proof type, and no attenuation type can be provided for customers to choose from.

Q: What are the types of common sensors

D：Proximity sensors (commonly known as proximity switches), fiber optic sensors, fiber optic amplifiers, photoelectric sensors, light curtain sensors, magnetic sensors, laser sensors, ultrasonic sensors, pressure sensors, temperature and humidity sensors, linear sensors, displacement sensors, Hall sensors.
