The conditions are given in the table below. However, satisfactory resolution cannot be attained in strong electromagnetic fields.The minimum resolution of the ZG2-WDS8T/WDS3VT is 0.25 ƒÊm, even when the average number of operations is increased. Resolution does not go any lower.

The CCD standard mode is used. *4Defined as 1/e2 (13.5%) of the center light intensity. This may be influenced when light leakage also exists outside the defined area and the reflectivity of the light around the measurement object is higher than that of the measurement object. 394 ZG2 Profile sensor Sensor controllers Item ZG2-WDC11/WDC11A ZG2-WDC41/WDC41A Input/output typeNPN PNP No. of connectable Sensor Heads1 per Controller No. of connectable Controllers2 Measurement cycle *1 16 ms (high-precision mode), 8 ms (standard mode), 5 ms (high-speed mode) Min. display unit10 nm Display range –999.99999 to 999.99999 Display LCD monitor 1.8-inch TFT color LCD (557x234 pixels) LEDs•Judgment indicators for each task (indication color: orange): T1, T2, T3, T4 •Laser indicator (indication color: green): LD_ON •Zero reset indicator (indication color: green): ZERO •Trigger indicators (indication color: green): TRIG External interface Input/output signal lines Analog outputs Select voltage or current (using the sliding switch on the bottom surface) •Voltage output: 10 to 10 V, output impedance: 40 •Current output: 4 to 20 mA, maximum load resistance: 300 Judgment output (ALL-PASSING/ERROR) Trigger auxiliary output (ENABLE/GATE) NPN open collector 30 VDC, 50 mA max.
