GENERAL DESCRIPTION
The Model ZSD encoder is ideal for applications requiring a miniature, high
precision, low cost encoder, designed with all metal construction for years of
trouble-free operation.
The NPN Open Collector outputs are each current limited to 20 mA. The
outputs are standard quadrature with index, available in resolutions up to 2500
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 max.) 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.
