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.
