countersinks on both sides (Polycarbonate) 2,000 - Reference Information for Model Selection - Sensing Distance vs. Digital Value The following graphs show how the digital value is high within the sensing range and small outside. This explains why false detection does not occur outside the sensing range, even against common metal backgrounds, such as stainless steel.
