  • SCOPE

    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:

    Equipment requirements are intended for use in an ambient temperature of 0 to 40° C unless specified otherwise.
