R58ECRGB1Q is a R58E series Expert™ registration mark sensor. It offers maintenance-free, solid-state reliability for typical color contrasts found in product and material registration application͘. Fast 50- microsecond sensing response produces excellent registration repeatability, even in ultra-high-speed application. R58E sensor features 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 condition individually. Dynamic TEACH provides a means for teaching a series of conditions only; the R58E samples the sensing events and automatically sets the switch point between the lightest and darkest conditions.
