ZSD Series
• High Precision Accuracy
• NPN Open Collector Output
• 6.33 mm (0.25") Shaft Diameter
• Quadrature Outputs with Indexing
The ZSD Series encoder is ideal for
applications requiring a miniature, high
precision, low cost encoder, designed with
all metal construction for years of troublefree operation.
The NPN Open Collector outputs are each
current limited to 20 mA. The outputs are
standard quadrature with index, available in
100 or 1000 pulses per shaft revolution.
The quadrature separation is typically
90 electrical degrees. Output A leads output
B for clockwise rotation of the encoder shaft.
OPEN COLLECTOR OUTPUT WIRING
The ZSD sensors have open collector
outputs. An open collector output brings
the uncommitted collector of the encoder
switching device to the external world.
Because the collector element is not
associated with the sensor supply voltage,
the sensor output collector may be “pulled
up” to external voltages (30 Vdc maximum)
different than the encoder supply voltage.
NPN open collector outputs are current
sinking devices. An output signal will not
be generated unless a pull-up resistor is
connected from the open-collector to the
positive side of an external supply. The same
supply can be used for powering the unit and
for the pull-up resistor.
