About IEC 62046 (Protective Equipment Application)

This hands-on workshop builds applied knowledge and team exercises around the certification requirements of IEC 62046.

IEC TS 62046 addresses the application of protective equipment detecting persons — bringing together ESPE, pressure-sensitive devices and vision systems into engineered safeguarding solutions: selection, positioning, integration, muting and validation.

What it regulates

Selection criteria among detection technologies, combined use with guards, muting design (sequence, sensors, time limits), presence sensing on whole-body access, and verification of complete safeguarding functions.

Who must comply

System integrators of palletizers, press lines, robot cells and conveyors where material must pass but people must not.

Key requirements of IEC 62046

  • Application planning from risk assessment to safeguard concept
  • Muting: valid initiation, monitoring, override limits, and lamps/indication
  • Whole-body detection and prevention of undetected presence behind the field
  • Integration with machine control per 13849/62061 and distance per 13855

Key concepts: IEC 62046

Differentiation
Sensor arrangements distinguishing pallets/products from people (timing, geometry, multiple beams).
Muting
Temporary automatic suspension of the protective function to let material pass, engineered so a person cannot exploit it.
Override
Controlled, limited-duration bypass to clear jammed material with enforced safeguards.
Presence sensing
Ensuring a person inside the cell keeps the machine inhibited (horizontal fields, cell scanners) against restart-behind-the-curtain accidents.

Frequently asked questions: IEC 62046

What makes a muting design acceptable?

Muting only during the valid material transit, initiated by a plausible sensor sequence unattainable by a walking person, time-limited, indicated, and returning to full protection immediately after transit — with the whole arrangement validated.

How is restart-behind-the-field prevented?

By covering the interior with presence detection (horizontal scanner fields, mats) or enforcing visibility-based manual reset stations positioned so the whole hazard zone is observed before restart.
