Reliably capture black stickers on a light background

An energetic reflex sensor detects a black surface in front of a very bright background.

Reliably detecting black stickers on a light background often poses physical challenges for standard sensors. The article shows how energetic reflex sensors of the P1KT series detect even highly absorbent surfaces through the targeted evaluation of the amount of light (remission) – and thus offer a cost-efficient, flexibly integrable solution for contrast detection in mechanical engineering.
