R58E sensors offer maintenance-free solid-state reliability for typical color
contrasts found in product and material registration applications. Fast 50-microsecond sensing
response produces excellent registration repeatability, even in ultra-high-speed applications.
This fast response, coupled with the small 1.2 x 3.8 mm (0.05" x 0.15") sensing image, allows
the detection of even small and inconspicuous registration marks.

R58E sensors feature TEACH mode sensitivity adjustment by presenting two sensing
conditions to the sensor. TEACH mode has two options: Static TEACH and Dynamic TEACH.
Static TEACH is used to position the two sensing conditions individually. Dynamic TEACH
provides a means for teaching a series of conditions on-the-fly; the R58E samples the sensing
events and automatically sets the switchpoint between the lightest and darkest conditions. The
sensor then determines which sensing condition is present for the shortest time and assigns
the Output ON condition to that event (therefore, LO/DO selection is automatic). The LO/DO
setting can then be reversed in SETUP mode.
