LABL-1 & LABL-2 Label Sensor
Operation Manual
The discrete output must not be connected to outputs from other
sensors (i.e. outputs from multiple sensors must not be connected
in parallel). Parallel connections may damage sensor output circuitry.
Sensor is not suitable for wash down or hazardous environments; a
separate enclosure with the appropriate ratings is recommended for
these applications.
IMPORTANT:
This product is an accessory or part of a system. Always read and
follow the manufacturer’s instructions for the equipment before connecting this product. Comply with all applicable codes and safety regulations. Failure to do so may result in damage, injury or death.
SHIMPO INSTRUMENTS
The LABL sensor combines small spot size and fast response to
achieve high-speed label detection. The LABL is capable of detecting a wide variety of adhesive labels on various backings. The
Learn key provides Standard, Thin and Custom Learn. Custom
Learn (LABL-2) provides a separate measurement on the gap and
on the label to allow for optimal detection of difficult labels.
Status LEDs provide visual indication of teach and error conditions. Key lock mode is available to lock the Learn key. Remote
learn input is provided. Light-ON / Dark–ON functionality is provided via the wiring connections (see M8 Connections section).
The sensor provides a discrete output that can be connected for
NPN and PNP operation. A PLC can be used to monitor the status
of the discrete output signal indicating label or gap presence as
required.
LEARN MODE
The Learn key (or remote Learn input) is used to set the detection
level for a specific label during set-up.
Standard Learn:
· Place the label gap in the sensor slot using the alignment marks
as a reference. For standard paper or foil labels press the Learn
key one time.
Thin Learn:
· Place the label gap in the sensor slot using the alignment marks
as a reference. For thin paper press the Learn key two times.

as a reference. Press the Learn key three times.
· Place the lightest area of the label in the sensor slot using the
alignment marks as a reference. Press the Learn key.
Place the label then the gap in the sensor slot to verify that the
Yellow LED indicates the presence of the label.

INSTALLATION
Install the sensor to allow the labels to pass through the fork using
the alignment marks on the sensor. Connect a standard M8 cable
to power and output as required. Do not use other cable without
verifying connections and wire colors or damage to the sensor
may occur.

OUTPUT SIGNALS
Discrete Output
The discrete output is a PNP/NPN configuration allowing the user
to provide a load on this output that is either pulled high to VDC
or low to ground. The load cannot exceed 100mA. This output is
typically connected to a PLC.
M8 CONNECTIONS
DIMENSIONAL DETAILS
CAUTION: Do not connect the discrete output to outputs from
other sensors (i.e. outputs from multiple sensors to be connected
in parallel) without verifying the voltages and connections prior to
applying power.
CLEANING
Isopropyl alcohol with a soft cloth may be used to clean the optics
area.
