R58 Expert ™ Registration Mark Sensors
Overview
R58 Expert (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.
The sensor uses a tri-color LED during either teach process and automatically selects a
red, green, or blue sensing beam, based on the contrast between the registration mark and
its background. For applications where the user wishes to select the sensing beam color,
individual colors may be enabled/disabled in SETUP mode.
Sensitivity may be fine-tuned at any time by simply clicking the “+” or “-” buttons on the
sensor. The eight-element bargraph display clearly displays the relative received signal
strength.
The discrete bipolar (one NPN and one PNP) outputs may be configured in SETUP mode to
include a 30-millisecond ON-delay and/or OFF-delay, if required.
TEACH and SETUP configuration may be accomplished either by using the push button on
the sensor, or by supplying input pulses via the remote TEACH input. The push buttons may
be diabled via the remote input.
The construction of the R58E is extremely robust, with a die-cast metal housing, plastic optics,
and IP67 and NEMA 6 leakproof design for harsh sensing environments.
