R58E Series Expert Registration Mark Sensors, R58 Expert offer maintenance free solid state reliability for typical color. contrasts found in product and material registration applications Fast 50 Power LED Output LED. 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 in x 0 15 in sensing image allows the detection of small and. inconspicuous registration marks Dynamic,ON Delay LED. Push Button, R58E sensors feature TEACH mode sensitivity adjustment by presenting two OFF Delay LED. sensing conditions to the sensor TEACH mode has two options Static TEACH and Dark Operate. Dynamic TEACH Static TEACH is used to position the two sensing conditions DO LED Switchpoint. individually Dynamic TEACH provides a means for teaching a series of conditions. Light Operate, on the fly the R58E samples the sensing events and automatically sets the LO LED 8 Segment. switchpoint between the lightest and darkest conditions The sensor then Bargraph. determines which sensing condition is present for the shortest time and assigns Static Display. the Output ON condition to that event therefore LO DO selection is automatic Push Button. If necessary the LO DO setting can 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 Figure 1 Sensor Features. 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. Sensitivity may be fine tuned at any time by clicking the or buttons on the. sensor The eight element barograph 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, Configuration is accomplished either by using the push buttons on the sensor or.
by supplying input pulses using the remote input The buttons may be disabled. using the remote input, The construction of the R58E is extremely robust with a die cast metal housing. plastic optics IP67 and NEMA 6 leakproof design for harsh sensing environments.

R58E Series Expert Registration Mark Sensors,Installation. Install the Lens, The lens may be installed at either of two lens ports see Figure 2 on page 3 The lens and the lens port cap are both threaded and. may be exchanged by hand no tools are required The lens and cap both include an o ring seal. Note The lens port cap must be installed on the unused port for reliable operation Fully seat the lens cap to ensure. a liquid tight seal,Mounting Considerations, The R58 Expert includes a total of eight size M5 threaded holes used for mounting These threaded holes are positioned to match the.
mounting hole patterns common to other registration mark sensors The R58E includes four M5 x 0 8 x 6 mm stainless steel cap screws. and a hex key wrench, The R58E focus is 10 mm 0 39 in from the lens surface The R58E must. be mounted within 3 mm 0 12 in of this distance from the surface of the. material for reliable sensing Figure 2 on page 3 Cap. Consider the following when mounting the R58E, When sensing a registration mark on a reflective shiny material. mount the R58E at an angle which places the lens centerline at. approximately 15 off perpendicular to the material s surface Lens.

Clear materials are poor reflectors of light When sensing a mark. printed on a clear material for example a clear poly web. position a reflective surface directly behind the clear material to. return light to the R58E The printed mark regardless of its color. then becomes the dark condition as it blocks the light from. reaching the reflective surface Most clear materials are also. shiny it is important to include a 15 skew angle when sensing. clear materials Figure 4 on page 3, Whenever possible sense a web material at a location where it. passes over a tension bar or roller to minimize the adverse 10 3 mm. effects of web flutter or sag Figure 3 on page 3 Figure 2 Mounting Distance and Lens Positions.

Sensor Configuration, The R58E is pre set to power up in Run mode and to sense the most recently taught registration mark Quickly optimize the sensitivity of. the R58E using one of two available TEACH modes Static TEACH or Dynamic TEACH. Static TEACH Both the Output ON and Output OFF conditions are presented and sensitivity can be adjusted manually using the push. Dynamic TEACH The registration mark is presented during actual sensing conditions and the sensitivity can be adjusted manually using. the push buttons,Remote TEACH, Configure the sensor either using the push buttons or using a remote switch Remote configuration also may be used to enter Setup. mode to set the ON and OFF delay and to disable the push buttons to prevent unauthorized adjustment of the configuration settings. To access this feature connect the gray wire of the sensor to 0 V dc with a remote switch between the sensor and 0 V dc. Follow the sequence of input pulses to configure the sensor see the procedures in this document The duration of each pulse. corresponding to a push button click and the period between multiple pulses are defined as T 0 04 seconds T 0 8 seconds. Push Button Enable Disable Lockout, In addition to its configuration function the remote input may be used to disable the push buttons for security Disabling the push. buttons prevents unauthorized adjustment of the configuration settings Connect the gray wire of the sensor as described in Wiring.

Static TEACH, In Static TEACH mode the sensor learns two sensing conditions after each is presented one time The sensor automatically positions the. switchpoint midway between the two conditions, The sensor returns to Run mode if either TEACH condition is not 2nd Taught 1st Taught.
