Low-voltage switchgear and controlgear - Part 5-2: Control circuit devices and switching elements - Proximity switches

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 DR 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 D1 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
