GENERAL DESCRIPTION

The Model ZOD and ZOH are Thru-Bore Encoders. The ZOD has a bore of

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.

The encoders have a flexible butterfly mount and blind hollow shaft. These

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.
