How to apply discrete sensors in the machine tool industry

How to apply discrete sensors in the machine tool industry Discrete sensor classification photoelectric switch, encoder, etc., become the fastest growing category in the sensor. In particular, the number of discrete sensors has increased very rapidly in recent years, and the application area has been further expanded.

Discrete sensors have a wide range of applications in the machine tool industry, and photoelectric sensors, proximity switches, gratings and Other discrete sensor products have applications.

For example, limit switches are used on the machine tool to realize the overtravel protection of the moving parts of the machine tool, photoelectric switches, proximity switches, etc. are used to achieve some functions such as detection, protection, feedback and status confirmation; the grating is widely used. Closed-loop control of the CNC system to improve the accuracy of CNC machine tools; if the machine must be required to achieve a certain level of security protection, you must use a security switch or light curtain and so on. As discrete sensors are used as weak electrical devices, there are many installation locations in the mechatronics equipment and systems, the space for installation is small, and the installation environment is relatively poor. In addition to paying attention to product functions and volume, people pay more attention to performance. Although the control system has a redundant design, the performance requirements for discrete sensors are still very demanding.

Therefore, the reliability of discrete sensors and the performance indicators for harsh environment tolerance are still very important.

Different types and types of machine tools have different requirements for sensors.

In general, the requirements of the machine tool for the sensor are stronger in reliability and anti-interference ability; can meet the requirements of corresponding accuracy and running speed or response speed; and it is convenient to use and maintain, and is suitable for the operating environment of the machine tool. However, it cannot be ignored that with the increase of the application range of sensor products and the continuous application of new requirements for machine tools by machine tool manufacturers, some sensor products that are suitable for harsh environments have gradually been favored by users. “The use of machine tools is introduced. The environment is worse than other industries, and there are factors such as vibration, moisture, dust, and oil. Therefore, users expect that they have extremely high stability, reliability, and economy.

Discrete sensor products with characteristics such as high temperature resistance, corrosion resistance, and electromagnetic interference are becoming more and more widely used in the machine tool industry.
