Developed specifically for the detection of diffuse materials, OPB609 series reflective-object sensors are unfocused, suiting them for detection of paper, labels, or any material with a matte finish.

Photoelectric sensors with background suppression are a more evolved version of the basic diffuse sensors used on public washroom sinks to control automatic faucets. Both in this rudimentary ...

Here is the circuit of a little label sensor ideal for detecting labels on bottles. The circuit offers a peak sensing distance of 2.5 mm (operating range 0.2 mm to 15 mm) backed up by the proven ...
