Registration Mark Sensors

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 on page 3, and four-

pulsetoeitherenableordisablethepushbuttons(0.04sec.≤“T”≤0.8sec.):

NOTE:Pushbuttonscanbedisabled/enabledfromtheremotelineonly.

Installation Notes

The R58E includes a total of eight size M5 threaded holes used for mounting (see dimension

drawing on page 11). 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") from the lens surface. The R58E must be mounted within 3

mm (0.12") of this distance from the surface of the material for reliable sensing

(Figure6).ConsiderthefollowingwhenmountingtheR58E:

•Wheneverpossible,itisagoodideatosenseawebmaterialatalocationwhereitpasses

over a tension bar or roller, to minimize the adverse effects of web “ﬂutter” or sag (Figure 7).

•Whensensingaregistrationmarkonareective(shiny)material,mounttheR58Eat

an angle which places the lens centerline at approximately 15° off perpendicular to the

material’s surface (Figure 8). This “skew angle” will minimize strong direct reﬂections (which

tend to overwhelm the sensor), and allow the sensor to discern the relatively small optical

contrast offered by differences in colors.

•Clearmaterialsarepoorreectorsoflight.Whensensingamarkprintedonaclearmaterial

(e.g., 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

8).

Lens Location

The lens may be installed at either of two lens ports (see Figure 6). 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.
