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.

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.

Only factory stocked part numbers are listed. Consult the factory for part number

and availability of other PPR and output configurations.
