Power
Sensor can be powered with 11–30V DC but optimum
performance is obtained with 24V DC. The negative side of
the power supply is grounded to the sensor body.
+Vin 24V DC
(11-30V DC)
50mA
Outputs
The NPN and PNP outputs are open-collector outputs. The
NPN output can sink up to 150mA and the PNP output can
source up to 150mA. Outputs are short circuit protected by
self-resetting internal fuses. These fuses will activate if the
outputs are connected directly to ground or power. Repeated
shorting will eventually cause the sensor to fail.
NPN Output
150mA maximum
PNP Output
150mA maximum
PNP Power In
+Vin maximum
(+30V DC)
The PNP POWER IN voltage must be connected to a supply
voltage and must not exceed +Vin (+30V DC).
Output Polarity
Output polarity determines whether the output signal will go low or high on the label edge.
Note: Output polarity also depends on the direction of label movement through the sensor (see figure on page 4).
