标准范围

IEC 60947的本部分适用于感应金属和/或非金属物体存在的感应式和电容式接近开关、感应声音反射物体存在的超声波接近开关、感应物体存在的光电接近开关和感应有磁场物体存在的非机械磁接近开关。这些接近开关是独立式的，具有半导体开关元件，并用于连接到额定电压不超过250 V 50 Hz/60 Hz交流或300 V直流的电路。本标准不适用于带有模拟输出的接近开关。与上一版相比，主要变化如下:-表3的修改-表8中电压骤降和电压中断抗扰度试验的修改-修改附件A的状态，现在提供信息。

This part of IEC 60947 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(s) 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.The main changes with respect to the previous edition are as follows:-modification of Table 3;-modifications of voltage dips and voltage interruptions immunity tests, in Table 8;-modification of status of Annex A, now informative.
