1 Repeatability was obtained using KEYENCE’s analogue sensor controller (RD-50) with the number of averaging measurements set to 64. Note: The ripple of the analogue output may be 1 mV or more due to co mmon mode noise when observed with an oscilloscope or a high-speed A/D conversion board. 2 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). *3 The ±5 V analog voltage output range (the ±
