<Measurement conditions> The measurement conditions are as follows unless otherwise designated: Ambient temperature of +23℃ (normal temperature), Supply voltage 24 VDC, Response time: High-resolution, Center of measurement range, Measurement target: 50 ☓ 50 mm white ceramic.
*1 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 in the range of the light axis.
*2 The response time is a time in which the sensitivity switching time has been added. The sensitivity switching time fluctuates within a max. range of 4 ms (6 ms for CD33-250N☐) depending on measurement conditions. Also, if the sampling period is long, the response time will also increase proportionately.
Ex.: Sampling period 500 µs → 1000 µs: Response time 12.5 ms → Approx. 25 ms
