此类产品的特点是大量程,而发展趋势是“网络接口”以及与限位开关的互用性。不管被称作什么—机械量传感器、位置传感器或者接近传感器,它们都是工厂自动化硬件的中流砥柱。它们应用于各种生产场合,包括连续加工、批量加工、设备、离散产品。新技术改变了机械限位开关(滚筒、按钮搭配可调整机械固体停止器),增加了智能、加固、高精度设备,可以感测更多种类的 Such products are characterized by a large range, and the trend is “network interface ” and interoperability with the limit switch. Regardless of what is referred to as a mechanical quantity sensor, a position sensor or a proximity sensor, they are the mainstay of the factory automation hardware. They are used in a variety of production situations, including continuous processing, batch processing, equipment, discrete products. The new technology has changed the mechanical limit switch (roller, button with adjustable mechanical solid stop), an increase of smart, reinforced, high-precision devices that can sense a wider range of
