MODELS ZOD AND ZOH - THRU-BORE ROTARY PULSE GENERATORS

GENERAL DESCRIPTION

0.25" (6.35 mm) and the ZOH is a 0.375" (9.5 mm) bore. These units are ideal for applications requiring a miniature, high precision, low cost encoder , designed with all metal construction for years of trouble-free operation.

encoders use two set screws that are 90° apart to clamp the encoder's hub to the motor shaft. The NPN Open Collector outputs are each current limited to 100 mA. The outputs are standard quadrature with index, and are 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 ZOD and ZOH encoders 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 different than the encoder supply voltage (30 VDC maximum). 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.
