^1 The value when the measurement target is a mirrored surface object measured in displacement mode, scan width/interval 120 µm/2 µm, and 8-times average ^2 Sampling cycle differs according to the manufacturing variation of individual measuring units. The value when the FINE mode is set to OFF. ^3 Display changes every ±0.3 µm. ^4 Varies depending on the setting ^5 Dedicated power supply for the monitor specified by KEYENCE. ^6 Select either the Limits mode or the Binary mode. ^*7 Select either the Distance mode or the Profile mode. （Only distance mode is available with the LT-9501HSO (5654) and LT-9001HSO (5655).） The rating of the NPN open-collector output is 30 mA (30 V or lower) maximum, and residual voltage is 0.5 V. The rating of the Non-voltage input is ON voltage 1 V or lower, and OFF current 0.6 mA or lower.
