Low-voltage switchgear and controlgear - Part 5: Control circuit devices and switching elements - Section 2: Proximity switches IEC 60947-5-2:1992 ED1

Publication date:   Sep 30, 1992

Scope

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 and photoelectric proximity switches that sense the presence of objects. 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.
