Notes:

1) Where measurement conditions have not been specified precisely, the conditions used were as follows: (connected to the controller) supply voltage 24 V DC, ambient temperature +20 ℃ +68 ℉, MZBC mode (adjustment unit: width of 100 μm 3.937 mil), unit light receiving time 100 μs, average number of samples 64, measurement center distance, and target object is a white, light-diffusing object.
2) It is a value in which the sensor heads connected to a controller Ver. 2.00 or higher.
3) The value is the average of height measurement in full width at the measurement center distance.
4) This is the measurement value of a pin gauge rounded surface in the edge position measurement (start of falling edge) calculation setting. The measurement object: white ceramic pin gauge (ø10 mm ø0.394 in), unit light receiving time: 200 μs, measurement value extraction: base light intensity control, average number of samples: 64, width smoothing: ±4, all others are the initial settings.
5) Value represents the error in comparison with the ideal line of height measuring range (full scale) for the height measurement of the measurement center position in the width direction. The value in the specifications is the value within ±7.5 mm ±0.295 in of the height measuring range.
6) This product complies with 21 CFR 1040.10 and 1040.11 Laser Notice No. 50, dated June 24, 2007, issued by CDRH (Center for Devices and Radiological Health) under the FDA (Food and Drug Administration).
7) This size applies when using measurement center distance and is defined as 1/e2 (13.5 % approx.) of the center light intensity. Leaked light occurs outside of the defined range; sensing performance may be affected when the reflectance around the detection point is higher than that detection point.
