1.1 Scope and object

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 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.

1.1DV.1 Modification of 1.1 by adding 1.1dv.1.1 - 1.1dv.1.2:

1.1DV.1.1 This equipment is for use in ordinary locations in accordance with Annex 101.dvb, Reference No. 1. In Canada, general requirements applicable to this equipment are provided in Reference No. 7 of Table 101.dvb.

1.1DV.1.2 These requirements cover electronic proximity switches for use on industrial machinery or mass-production industrial equipment as defined by Annex 101.dvb, Reference No. 4.

1.1DV.2 Modification of 1.1 by adding the following:
