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 ...

What's behind the target can make a tremendous difference in how well reflective sensors do their job. Consider a photoelectric sensor operating in simple diffused mode (i.e., as a proximity sensor).

When it comes to safety sensor selection, detection quality and reliability are two very important aspects to consider. Ease of installation has not, historically, been a major selection consideration ...
