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 reflective (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 reflectors 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.
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.
