Scope:
This part of IEC 60947 applies to proximity devices with an enhanced resistance to failure (PDF).
It specifies requirements for four different types of PDF.
NOTE Due to their enhanced resistance to failure, PDFs apply for instance to:
– interlocking devices (see ISO 14119);
– the detection of the presence or absence of protective devices (see ISO/TR 12100-1).
For a PDF used in applications where additional characteristics, dealt with in other standards, are required, it will be necessary to satisfy the requirements of all relevant standards.
