MODEL ZMD – MINIATURE LENGTH SENSOR

(Replaces MODEL LSM)

DESCRIPTION

Designed for light to medium duty sensing applications, the Miniature Length

Sensor, Model ZMD, is compact in size and easy-to-use.

It features a built-in spring-loaded torsion arm that provides a simple-to-

adjust torsion load, allowing the unit to be mounted in almost any orientation,

including upside down. Using a 6" or 200 mm wheel, the ZMD can be used on

almost any surface, while operating at speeds up to 3000 feet per minute. The

housing is a durable, conductive composite material that will eliminate static

build up. Whether you need to measure speed, position, or distances, the Model

ZMD is the ideal solution. For other pulse rates and/or wiring configurations,

contact the factory for further details.

Open Collector Output Wiring

The ZMD 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 (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.

SAFETY SUMMARY

All safety related regulations, local codes and instructions that appear in the

literature or on equipment must be observed to ensure personal safety and to

prevent damage to either the instrument or equipment connected to it. If

equipment is used in a manner not specified by the manufacturer, the protection

provided by the equipment may be impaired.
