適用范圍：This part of IEC 60947 applies to inductive and capacitive proximity switches that sense the presenceof metallic and/or non-metallic objects, ultrasonic proximity switches that sense the presence ofsound reflecting objects, photoelectric proximity switches that sense the presence of objectsand non-mechanical magnetic proximity switches that sense the presence of objects with amagnetic field.These proximity switches are self-contained, have semiconductor switching elements(s) andare intended to be connected to circuits, the rated voltage of which does not exceed 250 V50 Hz/60 Hz a.c. or 300 V d.c. This Standard is not intended to cover proximity switches withanalogue outputs.The object of this standard is to state for proximity switches:– definitions;– classification;– characteristics;– product information;– normal service, mounting and transport conditions;– constructional and performance requirements;– tests to verify rated characteristics.
