Note:
1. Resolution
The resolution is the peak-to-peak displacement
conversion value of the analog output. (Condi-

Engineering Data
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 accurately if
the reflection ratio of the object is extremely small (a black object) or
extremely large (an object with a glossy surface).
