<Measurement conditions>
The measurement conditions are as follows unless otherwise designated: specialized amplifier unit connected, Ambient temperature: 23℃ (normal temperature), Supply
voltage: 24 VDC, Sampling period: 100 μs (800 μs for CD5-W350/-W500/-W2000 models), Average number of times: 256, Center of measurement range, Measurement target
(specular reflection/specular mode: aluminum deposition mirror, diffuse reflection/diffuse mode: white ceramic), digitally measured values.
*1 In accordance with the FDA provisions of Laser Notice No. 56, the laser is classified per the IEC 60825-1:2014 standard.
*2 Defined with center strength 1/e2 (13.5%) at the center of measurement range. There may be leak light other than the specified spot size. The sensor may be affected when there is a highly reflective object close to the detection area.
*3 With an average of 4,096 times. Other conditions are the same as the <Measurement conditions> shown above.
*4 The factory setting is 100 μs for CD5-L(W)25A/-(W)30A/-(W)85/-(W)150, and 800 μs for CD5-W350/-W500/-W2000.
