Characteristics
The optics of E3T-SR4_ is changed and improved from E3T-SR3_.
maximum sensing distance of E3T-SR4_ is shorter than of E3T-SR3_. But E3T-SR4_ is the same as
E3T-SR3_ for the rating sensing distance. Please refer to the graph below for the detail.
For almost applications, there is no problem of the replacement.
there might be some problems of the replacement. So we recommend testing under the using
condition.
It might not be possible to detecting them, because the excess gain of E3T-SR4_ is higher than of
E3T-SR3_. Please examine to replace to the sensor that have function of sensitivity adjustment (Ex.
fiber sensor).
The sensing distance might not be enough, because the maximum sensing distance of E3T-SR4_ is
shorter than of E3T-SR3_. If it is possible to replace to through-beam type, please examine E3T-ST/-
FT. If it is necessary to replace to retro-reflective type, please examine E3Z-R.
The position of detecting might be changed, because there is some difference for the characteristic
and the lens position. Please examine to change and adjust the mounting position.
At the rated sensing distance, the excess gain of E3T-SR4_ is higher than of E3T-SR3_. And the
