标准摘要
[中文适用范围]： 适用于感测金属和/或非金属物体存在的电感式和电容式接近开关、感测声音反射物体存在的超声波接近开关、感测物体存在的光电接近开关以及感测物体存在的非机械磁性接近开关。感知带有磁场的物体的存在。这些接近开关是独立的，具有半导体开关元件，旨在连接到额定电压不超过 250 V 50 Hz/60 Hz ac 或 300 V dc 的电路。模拟输出。 [外文原描述]： Applies to inductive and capacitive proximity switches that sense the presence of metallic and/or non-metallic objects, ultrasonic proximity switches that sense the presence of sound reflecting objects, photoelectric proximity switches that sense the presence of objects and non-mechanical magnetic proximity switches that sense the presence of objects with a magnetic field. These proximity switches are self-contained, have semiconductor switching elements and are intended to be connected to circuits the rated voltage of which does not exceed 250 V 50 Hz/60 Hz a.c. or 300 V d.c. This Standard is not intended to cover proximity switches with analogue outputs.
