接近开关定义与用途=∕∕∕

接近开关又称无触点行程开关，它除可以完成行程控制和限位保护外，还是一种非接触型的检测装置，用作检测零件尺寸和测速等，也可用于变频计数器、变频脉冲发生器、液面控制和加工程序的自动衔接等。接近开关按工作原理可分为高频振荡型、电容型、感应电桥型、永久磁铁型和霍耳效应型等。

接近开关在航空、航天技术以及工业生产中都有广泛的应用。在日常生活中，如宾馆、饭店、车库的自动门，自动热风机上都有应用。在安全防盗方面，如资料档案、财会、金融、博物馆、金库等重地，通常都装有由各种接近开关组成的防盗装置。在测量技术中，如长度，位置的测量；在控制技术中，如位移、速度、加速度的测量和控制，也都使用着大量的接近开关。
