Product Sensor P/N: 4600-900
Tamp Pad and Label Low Sensors P/N: 6000-903 [kit]
Warning Tower P/N: 6150-828
The product sensor is an infrared, diffused
light model, capable of sensing objects at
distances up to 3 ft. (900 mm). The sensor has
two LED’s, one is a yellow detection
indicator and the other serves two purposes.
If no object is currently detected, the green
LED acts as a power on indicator. If the
sensor is detecting an object, the green LED
turns into a signal strength indicator. The
green LED will become brighter with a
strong return signal and dimmer with a weak
detection. The sensor can be mounted on the
baseplate, snorkel (wipe system), or remotely
on a mounting bracket. If a different sensor
is required, ensure it is a 24 VDC, NPN type.
6000-903 as shown
4600-903 is the older
style with a flat lens
The tamp pad sensors, auto ‐ retract and label
present, and the label low sensor are diffuse
light sensors. All three sensors are identical
with a quick disconnect M8 threaded
coupling. When the sensor is used for label
present, it is capable of detecting a wide
range of materials, colors (including clear),
and textures. When used for auto ‐ retract, the
sensor can detect object presence up to 3
inches (for white opaque, 2 inch for brown
corrugate) away from the tamp pad. As a
label low sensor, the presence of material
remaining on the roll at a fixed diameter can
be determined.
The warning tower incorporates three
incandescent bulbs, with three colored
lenses. These bulbs are 24 volt, 5 watt, and
can be changed to LED bulbs (6145 ‐ 503) for
longer life. The green segment indicates a
warning and error ‐ free, online condition.
The yellow segment indicates a warning or
offline condition. The red segment indicates
an error condition where the unit is placed
offline.
