BGS/FGS switchable

BGS : Background suppression

  • The sensor doesn't detect objects or background being out of the setting distance.
  • This mode is suited for the detection of a target without background.

Detection principle

FGS: Background recognition: BGR (Foreground suppression)

  • The sensor recognizes a background and detects a target by sensing the change in received light intensity.
  • This mode is suitable for the detection of a target on a stable background.

Detection principle

NPN/PNP dual output

The dual output enables inventory management more efficient. Model numbers followed by "P" are PNP models for which PNP output is allocated to the primary (black/ PIN 4) output.

Unique optical design realizes better performance and long detection distance with the compact housing (Short range models)
