*1 Display reading used as a guide for the detecting distance. When the setting value is tuned, the readout shifts. When the value exceeds “-99”, “-FF” is displayed.
*2 The laser classification for FDA (CDRH) is implemented based on IEC60825-1 in accordance with the requirements of Laser Notice No.50.
*3 M8 connector (3-pin) type does not include the external input function.
*4 When the response time is 10 ms
*5 Have passed resistance tests with cleaning agents from multiple manufactures.
