Resolution 2. Response Time The resolution is the peak-to-peak displacement The delays are the 10% to 90% rising and conversion value of the analog output. falling times of the analog output in response (Conditions: white alumina ceramic at the to a sudden change in the displacement. measurement point) Displacement Output fluctuation 90% 10% Analog displacement output Tr Ti Engineering Data (Reference Value) Linearity Characteristics vs. Objects Linearity characteristic curves are obtained by detecting an object at different positions within the measurement range and plotting the analog output error resulting from each operation. The LED Displacement Sensor cannot detect an object accu- rately if the reflection ratio of the object is extremely small (a black object) or extremely large (an object with a glossy surface). 2
