INPUT VOLTAGE: 4.75 to 28 VDC max for temperatures up to 85C 4.75 It features a built-in spring-loaded torsion arm that provides a simple-to- to 24 VDC for temperatures between 85C to 100C, reverse polarity adjust torsion load, allowing the unit to be mounted in almost any orientation, protected. including upside down. Using a 6 or 200 mm wheel, the ZMD can be used on 2. INPUT CURRENT: 100 mA max (65 mA typical) with no output load almost any surface, while operating at speeds up to 3000 feet per minute. The 3. OUTPUTS: NPN Open Collector Transistor, V = 30 VDC max. 20 mA OH housing is a durable, conductive composite material that will eliminate static max. current. Incremental - Two square waves in quadrature with A leading build up. Whether you need to measure speed, position, or distances, the Model B for clockwise rotation, as viewed from the wheel side. ZMD is the ideal solution. For other pulse rates and/or wiring configurations, 4. MAX FREQUENCY: 200 KHz standard contact the factory for further details. 5. NOISE IMMUNITY: Tested to BS EN61000-6-2 BS EN50081-2 BS EN61000-4-2 BS EN61000-4-3 BS EN61000-4-6, BS EN500811 (Tested Open Collector Output Wiring with 2 meter cable) The ZMD sensors have open collector outputs. An open collector output 6. SYMMETRY: 180 (18) electrical brings the uncommitted collector of the encoder switching device to the external world. Because the collector element is not associated with the sensor supply 7. QUAD. PHASING: 90 (22.5) electrical voltage, the sensor output collector may be pulled up to external voltages 8. MIN. EDGE SEP: 67.5 electrical different than the encoder supply voltage (30 VDC maximum). NPN open 9. ACCURACY: Within 0.017 mechanical or 1 arc-minute from true position. collector outputs are current sinking devices. An output signal will not be (for PPR>189) generated unless a pull-up resistor is connected from the open-collector to the MECHANICAL SPECIFICATIONS positive side of an external supply. The same supply can be used for powering 1. MAXIMUM MECHANICAL SPEED: 6000 RPM. Higher speeds may be the unit and for the pull-up resistor. achievable, contact the factory. 2.
