FGS (Foreground Suppression) sensors are able to reliably detect rough and black surfaces due to the PSD sensing element.

A digital display is the ideal way to verify the sensitivity setting.

Mechanical toughness tested to 100G shock resistance.

3% Hysteresis
It is possible to sense a target that is 3 mm thick at 100 mm distance.

Thin object on flat background

FGS-D series can detect anything on the flat background due to its fore ground suppression feature.
Vibrating conveyor

BGS-D series can detect anything in front of the background due to its background suppression feature.
PC board lying on conveyor

FGS-D series can detect thin PCB, printed circuit board, lying on the conveyor due to its fore ground suppression feature.
Tin can

BGS-D series can detect tin can stably even the surface is glossy due to its background suppression feature.
