Datasheet

• No user adjustments – Adaptive Digital Logic (ADL™)
revolutionary self-learning capability.

• Continuous automatic internal adjustment of sensing threshold and drift
compensation.

• Registration accuracy of ± 0.3 mm (0.012") typical at web speeds up to

1.5 m per second (5 ft per second)

• Reliably detects the presence of most types of labels on web backing

◦ Clear labels on an opaque backing
◦ Clear labels on a clear backing
◦ Opaque labels on an opaque backing
◦ Opaque labels on a clear backing

• Perfect for label-registering applications, and also for label-counting tasks
in slitting or rewinding applications.

• Heavy-duty metal housing, 1 mm (0.04") slot

Model Number

SLC1BB6
SLC1BB6Q 5-pin Euro-style (QD)

To order the 9 m (30 ft) cable models, add the suffix “W/30” to the model number of the cabled version (e.g., SLC1BB6
W/30). A model with a QD connector requires an accessory mating cable.

provides

Never use this device as a sensing device for personnel protection. Doing so could lead to
serious injury or death. This device does not include the self-checking redundant circuitry necessary

to allow its use in personnel safety applications. A sensor failure or malfunction can cause either an
energized or de-energized sensor output condition.

The SLC1 Series Label Sensor was developed to provide trouble-free
detection of labels on web backing material. It reliably senses the
difference between materials of extremely low visual contrast, including
clear labels on clear or opaque backing. The SLC1 uses Banner’s
exclusive Adaptive Digital Logic (ADL™) to automatically make all sensor
settings; no user adjustments are necessary.

NOTE: Labels with metallic inks, foil embossing or
metal substrates are not recommended for use with
SLC1 Series sensors.

Installing the SLC1 Series Label Sensor

Mount directly and securely to a firm surface using M4 (#8)
hardware (bolts not included). See dimensions for mounting
hole locations. To lessen the effects of web flutter, position
the bottom fork of the sensor slightly above the web’s path
so that the web can glide over the bottom fork with slight
tension.

For the most reliable operation, take steps to eliminate
static electricity near the SLC1 Label Sensor.

Figure 2. Allowing the web to glide over the bottom fork with slight

tension lessens the effects of web flutter.

Operating the SLC1 Series Label Sensor

The SLC1 Series is self-teaching and needs no programming;
there are no adjustments to set. Simply align the label web
in the slot, between the guides, and allow the labels to run
through the sensor. After the passing of four successive
labels or 250 milliseconds (whichever is greater), the SLC1
learns the characteristics of the labels and adjusts for the
proper sensing threshold and drift compensation.

For best self-programming results, turn power to the sensor
ON or perform a reset after the web has been positioned in
the slot. Align the labels within the web alignment guides on
the side of the sensor slot as completely as possible.

For best repeatability, position the label to cover the entire
sensing area (between the sensor’s web alignment guides,
see Figure 2 on page 2). Some label configurations are
sensed with greater repeatability than others; the sensor
performs best when there is an abrupt change between
labels. For example, labels with sharply defined edges that
are perpendicular to the web direction and have larger gaps
between labels are sensed most easily. Tiny gaps between
labels and labels whose shape tapers at the leading and
trailing edges are more difficult to sense.

Figure 3. SLC1 Label Sensor preferred sensing configurations

If sensing a label with a shape like that shown in Figure 4 on page 3, the best repeatability results if the most
perpendicular edge of the label is aligned fully within the sensing area.
