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;
-
process industry;
-
power plants.
Special applications (e.g. corrosive atmosphere) can cause additional requirements.
Products covered by the scope of this document are expected to be selected, installed, and maintained by skilled personnel only.
NOTE 1 Analog proximity devices can be linear or non linear.
NOTE 2 The specific requirements, characteristics, and test procedures for an analog output interface which are described in Clauses 5, 6 and 9 of this document, are based on requirements written in IEC 61131‑2:2017.
