Low-voltage switchgear and controlgear - Part 5-2: Control circuit devices and switching elements - Proximity switches

EN-IEC 60947-5-2 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.

Amandma A11:2022 je dodatek k standardu SIST EN IEC 60947-5-2:2020.
EN-IEC 60947-5-2 se uporablja za induktivna in kapacitativna približevalna stikala, ki zaznavajo kovinske in/ali nekovinske predmete, ultrazvočna približevalna stikala, ki zaznavajo predmete, ki odbijajo zvok, fotoelektrična približevalna stikala, ki zaznavajo predmete, in nemehanska magnetna približevalna stikala, ki zaznavajo predmete z magnetnim poljem. Izdelki, za katere se uporablja ta dokument, niso izpostavljeni določenemu obnašanju ob okvarnih razmerah. Približevalna stikala z opredeljenim obnašanjem so zajeta v standardu IEC 60947-5-3 in morajo izpolnjevati dodatne zahteve. Navedena približevalna stikala so samostojna, imajo polprevodniške stikalne elemente in so namenjena za priključitev v omrežja, katerih naznačena napetost ne presega 250 V 50 Hz/60 Hz izmenične napetosti RMS ali 300 V enosmerne napetosti. Primeri tipične uporabe za izdelke, za katere se standard uporablja: – tovarniška avtomatizacija in strojna industrija; – logistična in embalažna industrija; – tekoči trakovi, dvigala; – predelovalna industrija; – elektrarne. V posebnih primerih uporabe (npr. v korozivni atmosferi) je treba upoštevati dodatne zahteve. Ta dokument ne zajema približevalnih stikal z analognimi izhodi. Cilj tega dokumenta je za približevalna stikala navesti: – definicije; – razvrstitev; – lastnosti; – informacije o izdelku; – običajne pogoje uporabe, montaže in transporta; – konstrukcijske in izvedbene zahteve; – preskuse za preverjanje nazivnih lastnosti.
