The ZDH Series of sensors are heavy-duty,extremely rugged, reliable, yet compactencoders designed for harsh factory and plantfloor environments. These encoders are flangemount and conform to NEMA 4, and 13 (IP66)standards.

ApplicationsTypical applications include motion controlfeedback, machine control, processcontrol, elevator controls, conveyors, textileequipment, robotics and food processing.

See SPECS above for full specifications and additional information.

Open CollectorOutput Wiring
The ZDH Series of sensors have opencollector outputs. An open collector outputbrings the uncommitted collector of theencoder switching device to the externalworld. Because the collector element is notassociated with the sensor supply voltage,the sensor output collector may be “pulledup” to external voltages different than theencoder supply voltage (40 Vdc maximum).NPN open collector outputs are currentsinking devices. An output signal will notbe generated unless a pull-up resistor isconnected from the open-collector to thepositive side of an external supply. The samesupply can be used for powering the unit andfor the pull-up resistor.
