<Measurement conditions>
The measurement conditions are as follows unless otherwise specified: Ambient temperature: 25°C (Room temperature); Supply voltage: 24 V DC; Sampling period: 200 μs; Moving average: 128 times; Median filter: 31; at the center of measurement range, White ceramic as a standard target object. The sensor is mounted on an aluminum bracket.

*1: In accordance with the guidance of Laser Notice No. 56 by FDA, the lasers are classified per the IEC 60825-1:2014 standard.
*2: There may be light leakage outside of the beam spot. If there is a highly reflective object close to the measurement area, measurement results may be affected.
*3: The smallest step to change a measurable distance between the target and sensor, at the moving average of 512.
*4: Peak to peak value of measurement in stationary state (at moving average of 512)
*5: Set to 200 μs by default.
*6: A typical data measured when an object of white ceramic and sensor are mounted on an aluminum brackets.
