MODEL ZDH - 2" FLANGE MOUNT ROTARY PULSE GENERATOR
MODEL ZNH - 2.5" FLANGE MOUNT ROTARY PULSE GENERATOR
(REPLACES THE MODEL RPGD AND RPGN RESPECTIVELY)
GENERAL DESCRIPTION
The ZDH and ZNH series of sensors are heavy duty, extremely rugged,
reliable, yet compact encoders designed for harsh factory and plant floor
environments. Both models are flange mount and conform to NEMA 4, 13
and IP66 standards. Typical applications include motion control feedback,
machine control, process control, elevator controls, conveyors, textile
equipment, robotics and food processing.
Open Collector Output Wiring
The ZDH and ZNH series of 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 different than the encoder supply voltage (40 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.
REPLACEMENT
Note: The RPGD connections are made by a 24 inch cable. The ZDH uses a
7-Pin MS connector.
