*1. The values are for N8.5 Munsell paper.
*2. The spot diameter is defined by 1/e2 of the Sensor's laser beam center. Although a sub-beam may be observed around the main beam, this does not mean that the product is defective.
 *3. Refers to input impedance of a device to be connected.
 *4. Resolution (Z4D-F04A) The resolution is the peak-to-peak displacement conversion value of the analog displacement output (Conditions: N8.5 Munsell mat paper at the center of measurement point with a power ripple noise of 10 mV (p-p) max.)


*5. The value is the peak-to-peak error rate of a displacement output voltage line with N8.5 Munsell mat paper. The value varies with the sensing object.
 *6. Response Time (Z4D-F04A) The response time of the Sensor (Z4D-F04A) is the time required for the analog displacement output to increase from 10% to 90% of the full value (at the rise time) or decrease from 90% to 10% of the full value (at the fall time).


        The response time of the Sensor (Z4D-F04D): ON/OFF switching time
 *7. The value is at the sensing range of 4 mm.
