1 Scope
This part of IEC 60947 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. Figure 1 shows the schematic principle of such a device. They might consist of one or more
parts.
The requirements of IEC?60947?5?2 , Low-voltage switchgear and controlgear - Part 5-2: Control circuit devices and switching
elements - Proximity switches, apply with the additions and modifications as stated in this document. The clause
numbering in this document follows the clause numbering of IEC?60947?5?2 , modified where necessary.
This document does not apply to industrial process measurement transmitters according
to IEC?62828?series .
Examples of typical applications for in-scope products:
factory automation and machinery industry;
logistic and packaging industry;
conveyor belts, lifts;
