ČSN EN IEC 60947-5-7 ed. 2

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.
