SICK WL24-2X430 Overview



Reflex Photoelectric Switch WL24-2X430 Ex II 2G Es 1a op is IIC T4

SICK WL24-2X430 Description



  • Classification: EX II 2G Ex ia op is IIC T4 according to Directive 94/9/EC (ATEX)
  • Corresponds to Category 2G
  • Output type: EN 60947-5-6 (NAMUR)
  • Long sensing range
  • Red light
  • M12 or terminal chamber connection: 90 rotatable
  • Durable metal housing
  • Your benefits

  • Allows longer sensing range despite the limited factors of the norms for Category 2G (ATEX, explosive environments)
  • Metal housing that has been IP 69K tested provides reliability and a long service life
  • Flexible installation due to 90 rotatable connector
