BS EN IEC 60947-5-2:2020

This standard BS EN IEC 60947-5-2:2020 Low-voltage switchgear and controlgear is classified in these ICS categories:

• 29.120.40 Switches
• 29.130.20 Low voltage switchgear and controlgear

This part of IEC 60947 applies to inductive and capacitive proximity switches that sense the presence of metallic and/or non-metallic objects, ultrasonic proximity switches that sense the presence of sound reflecting objects, photoelectric proximity switches that sense the presence of objects and non-mechanical magnetic proximity switches that sense the presence of objects with a magnetic field.

Products covered by the scope of this document are not subjected to defined behaviours under fault conditions. Proximity switches with defined behaviour are covered by IEC 60947-5-3 and have to fulfil additional requirements.

These proximity switches are self-contained, have semiconductor switching element(s) and are intended to be connected to circuits, the rated voltage of which does not exceed 250 V 50 Hz/60 Hz AC RMS or 300 V DC.

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.

This document is not intended to cover proximity switches with analogue outputs.

The object of this document is to state for proximity switches:

• definitions;

• classification;

• characteristics;

• product information;

• normal service, mounting and transport conditions;

• constructional and performance requirements;

• tests to verify rated characteristics.

Products covered by the scope of this document are expected to be selected, installed, and maintained by skilled personnel only.
