*1 Repeatability was obtained using KEYENCE's analog sensor controller (RD-50) with the number of averaging measurements set to 64.
Note: The ripple of the analog output may be 1 mV or more due to common mode noise when observed with an oscilloscope or a high-speed A/D conversion board.
*2 When measurement is impossible, 12 V (31.2 mA) is output.
*3 LK-010: When measurements cannot be performed, this is 12 V (21 mA). LK-035/030, LK-085/080, and LK-500: When measurements cannot be performed, this is 12 V (31.2 mA).
