Due to convergent distance sensing, the color or material of the object has almost no effect. Further, the background also has very little effect, enabling stable sensing.

EX-43: Correlation between material and sensing range

Compact size (W10 x H29 x D18 mm W0.394 x H1.142 x D0.709 in)

It can be installed in a limited space.

Various applications

Diffused beam type

Even in a limited sensing area, the sensor is not affected by small perforations or unevenness. It is suitable for presence detection.

Spot-beam type

– Visible red spot beam allows easy targetting.
– It is suitable for positioning because of its 0.05 mm 0.002 in repeatability.
