1.2 Different Types of Electro-Sensitive Protective Equipment (ESPE)

IEC 61496 defines the standards for electro-sensitive protective equipment (ESPE), outlining both general requirements and specific sensing technologies to ensure safe operation in industrial environments.

Structure of IEC 61496:

  • IEC 61496-1: This part provides the generic principles and performance requirements applicable to all types of ESPE. It serves as the foundational framework for safety equipment design and functionality.
  • IEC 61496-2 to 5: These parts focus on the specific technologies used in ESPE systems, categorized as follows:
    • IEC 61496-2: Active Opto-Electronic Protective Device (AOPD) – Utilizes light beams for detection.
    • IEC 61496-3: Active Opto-Electronic Protective Device Responsive to Diffuse Reflection (AOPDDR) – Relies on light reflections for object detection.
    • IEC TS 61496-4: Vision-Based Protective Device (VBPD) – Employs cameras or image-processing technologies for area monitoring.
    • IEC TS 61496-5: Radar Protective Device (RPD) – Uses radar waves for detecting presence and motion, offering a robust alternative to optical systems
