Low-voltage switchgear and controlgear - Part 5-7: Control circuit devices and switching elements - Proximity devices with analogue output

Scope

IEC 60947-5-7:2024 states the requirements for proximity devices that correspond to the scope of IEC 60947-5-2:2019 with analog output (PDAO) and/or a digital output to transmit a corresponding digital value representing the detected sensing input. These devices can provide additional parameters.

This second edition cancels and replaces the first edition published in 2003. This edition constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous edition:

a) New structure;

b) Update and expansion of definitions on analog output properties;

c) Expanded performance requirements on analog output;

d) Update and new normative references;

e) Update of EMC requirements;

f) Harmonization with IEC 62828 series;

g) Harmonization with IEC 62683 and IEC 61987 definitions;

h) Harmonization with IEC 61131-2 requirements;

i) Update of the Annex A (former Annex G), Example of the determination of the conformity;

j) New Annex B, Overview tests and influence quantities;

k) New Annex C, Additional requirements for proximity switches with analog output incorporating a built-in communication interface complying with IEC 61131-9;

l) New Annex D, Main characteristics for proximity devices with analog output.
