Note: 1. Refers to the distance from the detecting surface to the passing position of the detectable object which permits positive detection
even when the sensing detecting surface is decreased due to temperature or voltage fluctuation.
2. The response frequencies for DC switching are average values measured on condition that the distance between each sensing
object is twice as large as the size of the standard object and the sensing distance set is half of the maximum sensing distance.
3. Refers to a change in detecting distance when the ambient operating temperature changes within Omron’s specified range and
is expressed as the rate of variation (in percentage) with the detecting distance at the rated voltage taken as 100%.
4. Refers to a change in detecting distance when the supply voltage changes within a permissible range and is expressed as the
rate of variation (in percentage) with the detecting distance at the rated voltage taken as 100%.
