*1 Note: You may not be able to connect the sensor head to the amplifier unit depending on when the amplifier unit was purchased. For details, contact your local sales office.
*2 The measuring range represents the range at which measured values can be displayed. The operating range is the actual movable range of the spindle.
*3 Within ±0.3 mm 0.012" from the center of the measuring range, the width for any 0.2 mm 0.008" is 1 µm. The entire area is 2 µm.
The linearity for the entire measuring range is ±0.15 % of F.S. (F.S.: 5 mm 0.20")
*4 Value when the ambient temperature is 20 °C 68 °F.
*5 Representative value at the center of the measuring range. Please note that the measuring force varies depending on the installation orientation of the dust boot.
*6 When an M8 oil-resistant cable (GT2-CHP2M/CHP5M/CHP10M) is used for the sensor head cable.
*7 Contacts are available as options sold separately.
*8 Including the relay connector.
