Overview
EN IEC 60947-5-2:2020/A11:2022 is a CENELEC amendment to the low‑voltage switchgear and controlgear standard that adds specific requirements for proximity switches with integrated radio functionality. Published April 2022, Annex ZC supplements EN IEC 60947-5-2:2020 by defining additional safety (Article 3.1(a)) and electromagnetic compatibility (EMC) (Article 3.1(b)) requirements in support of Directive 2014/53/EU. The amendment applies when radio technologies are incorporated in a fixed and permanent manner into proximity switches.
Key topics and technical requirements
- Scope & applicability: Adds Annex ZC which applies to proximity switches incorporating one or more radio technologies listed in Table ZC.1 (e.g., SRD, broadband data, ROMES/ROGNSS, UWB).
- Normative references: Incorporates relevant EMC and human‑exposure standards such as EN 55032, EN IEC 61000-6-4:2019, EN 62479:2010, EN IEC 62311:2020, and ETSI radio EMC standards (ETSI EN 301‑489 series).
- New terms and ports: Defines radio‑related terminology (antenna port, exclusion band, wired network port, radio equipment) to standardize test interfaces and reporting.
- Human exposure (EMF): Radio functions are assessed using EN 62479 routes B or C. Low‑power exclusion thresholds (Pmax) are specified:
- Industrial environment: P = 200 mW (if 100–200 mW, documentation must restrict use near head/trunk).
- General public exposure: P = 40 mW (if 20–40 mW, documentation must restrict use near head/trunk).
- If exclusion levels are not met, further assessment per EN IEC 62311:2020 Clause 5 is required.
- EMC testing and performance criteria:
- EUT (equipment under test) must be configured to maximize emissions and susceptibility.
- Radio functions tested in standby, receive‑only, and transmit/combined modes where applicable.
- Exclusion bands and radio‑specific EMC tests follow the ETSI standards listed in Table ZC.1.
- Radiated and conducted emissions requirements reference EN IEC 61000‑6‑4 and ETSI subclauses; test configurations and rationale must be recorded in the test report.
Applications and who uses it
- Product designers and manufacturers of proximity switches that integrate wireless features (Bluetooth, UWB, short‑range radios, GNSS receivers).
- EMC and safety compliance engineers preparing conformity assessments under Directive 2014/53/EU (Radio Equipment Directive).
- Test laboratories performing EMC, radiated emissions, and human exposure assessments.
- Regulatory and certification bodies validating national adoption of CENELEC standards.
Related standards
- EN IEC 60947-5-2:2020 (base standard)
- EN 62479:2010, EN IEC 62311:2020 (EMF/human exposure)
- EN IEC 61000-6-4:2019 (industrial emissions)
- ETSI EN 301‑489‑3 / ‑17 / ‑19 / ‑33 (radio EMC specifics)
This amendment ensures proximity switches with embedded radio functions meet harmonized European safety and EMC expectations and guides manufacturers on testing, documentation, and risk‑based usage restrictions.

The radio function shall first be assessed in accordance with the requirements set out in EN 62479:2010 by

with the requirements if the available antenna power and/or the average total radiated power is less than or
equal to the applicable low-power exclusion level P of the ICNIRP Guidelines, as specified in the first 4 rows
max
of EN 62479:2010, Table A.1.
If the proximity switch is exclusively intended to be used in an industrial environment, the limit P is 200 mW.
max
If P is between 100 mW and 200 mW then the manufacturer’s documentation shall state that this product
max
shall not be used near to head and trunk.
If the intended use of the proximity switch includes exposure to the general public, the limit P is 40 mW. If
max
P is between 20 mW and 40 mW then the manufacturer’s documentation shall state that this product shall
max
not be used near to head and trunk.
If the low-power exclusion level P is not met when applying route B or route C, the radio function shall be

further assessed according to EN IEC 62311:2020, Clause 5.
Information on the intended environment (industrial or general public) and any restrictions shall be provided in
addition to the requirements of 6.1.

The article discusses the EN-IEC 60947-5-2 standard, which applies to various types of proximity switches used for sensing the presence of objects. These include inductive and capacitive proximity switches for metallic and non-metallic objects, ultrasonic proximity switches for sound reflecting objects, photoelectric proximity switches for objects, and non-mechanical magnetic proximity switches for objects with a magnetic field. The standard does not specify behavior under fault conditions and is not intended to cover proximity switches with analog outputs. The document outlines definitions, classification, characteristics, product information, conditions for normal service, mounting, and transport, constructional and performance requirements, and tests to verify rated characteristics. Proximity switches covered by this document should be selected, installed, and maintained by skilled personnel. Typical applications for these switches include factory automation, the machinery industry, logistics and packaging industry, conveyor belts, lifts, process industry, and power plants. Additional requirements may be needed for special applications in corrosive atmospheres.
The EN-IEC 60947-5-2:2020/A11:2022 standard regulates control circuit devices and switching elements known as proximity switches. These switches can detect the presence of metallic, non-metallic, sound reflecting, and magnetic objects. The standard applies to proximity switches with semiconductor switching elements that can be connected to circuits with a rated voltage up to 250V AC or 300V DC. It does not cover proximity switches with analogue outputs. The document provides definitions, classification, characteristics, product information, and requirements for construction, performance, and testing. These proximity switches are commonly used in factory automation, machinery, logistics, packaging, conveyor belts, lifts, and power plants. Certain special applications may require additional requirements. Skilled personnel should be responsible for selecting, installing, and maintaining these switches.
