MODEL ZLZ - LINEAR CABLE ENCODER

(Replaces MODEL LES)

DESCRIPTION

The Linear Cable Encoder can provide an accurate, yet low cost solution for

Linear Measurement applications. Common applications include robotics,

extrusion presses, valve positioning, textile machinery, and gate control

positioning, just to name a few. The ZLZ has some unique advantages over

other sensing solutions. Using a stainless steel cable, perfect parallel alignment

is no longer required and with a 50 inch cable reach, it can easily be mounted

away from harsh environments. The ZLZ is available in a quadrature output,

allowing the sensor to operate in positioning applications.

Additional cable exit configurations, pulses per inch, and mating connectors

are available on special request. Contact the factory for details.

Open Collector Output Wiring

The ZLZ 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 (40

VDC max.) different than the encoder supply voltage . 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.
