There are various types of sensors, how to select them?

First of all, current sensors, voltage sensors, etc., almost all sensors are passive electronic components, and this characteristic cannot be changed.

Therefore, whether it is a large foreign company or a small domestic company, each company's product manual is limited. In the early 1980s, our domestic sensors were mainly Japanese "at the beginning of the day" NANA "Asahi Kasei" "LEM" and LEM""HONEYWELL ".As a customer, there was little choice, and they could only be actively selected in the process of space and circuit structure design or equipment structure design. As a result, As a sensor, it has become a component product with strong initiative in the first 10 years, which deviates from the market essence of the sensor itself. In the past 30 years of development, our domestic products have no choice but to follow those big companies and imitate them in structure and appearance design. At least 70% of the products on the market at present are like this. Today, when the products are homogenized, it can only be vicious competition in price.

Horribly, the sensor implements recommended standards, there is no mandatory standard, and the instructions are also cross-referenced, which has no reference value at all.

The models are also varied, and each manufacturer has its own naming method. The models are strange, and there are traders and manufacturers, and the models are different. It is more difficult for customers to choose products with the same parameters, many of which have different shapes and prices. It is better to learn how the sensors come from than to choose the models, which makes many user engineers confused.

As a sensor manufacturer, salespeople only know the basic functions of their products, but know nothing about performance and application. Especially, large foreign companies will not patiently recommend valuable and suitable things to customers and impose AE services on users.

This market is really chaotic. As a relative expert who has been involved in this industry for a long time, it is really sad that we can't keep up with the mouth of a master of deception.

Special reminder to users, if you have any questions, please communicate with the manufacturer directly by email or telephone, and put forward specific requirements, so that the engineers of the manufacturer can serve you instead of amateurs in the marketing department.
