Cautions on Length Measurement
After powering on, wait for 30 minutes before use. Failure to observe this caution may cause drift for length
measurement values.
Dusts, water, oil, etc. on the window part of the equipment may cause a length measurement error.
Wipe off deposits with clean air. If dirt is heavy, wipe it off with a soft, alcohol-soaked cloth.
Floating objects, droplets, etc. between the equipment and target measurement object may cause a length
measurement error.
Apply a protective cover, air purge, etc.
A length measurement error may occur depending on the state or form of the surface of the target
measurement object.
Calibration using the actual target measurement object can allow more accurate measurement.
A length measurement error may occur depending on the located state of the equipment.
Confirm that the measurement distance is correct and the equipment is located horizontally to the carrying
direction of the target measurement object.
Calibration after installation can allow more accurate measurement.
A length measurement error may occur if the target measurement object vibrates.
Length may not be measured if the target measurement object moves in a direction vertical to the length
measurement direction.

⑤Mounting screw holes
Mount the main unit with four M4 screws. The board thickness of the screw hole parts is 6 mm. Select the screw
length depending on the location where the main unit is fixed. To prevent screws from loosening by vibration, it is
recommended that you take screw locking action.
(For how to fix the main unit, see section 1-4-1.)
⑥Optical window
Irradiates LED light to measure the length, and receives light diffuse-reflected by the target measurement object.
Protected by the cover glass.
⑦Length measurement direction
The direction of the arrow shown in the figure indicates the length measurement direction (work moving direction).

1-4. Installation/Connection
1-4-1. Fixing the main unit
Mount the main unit with M4 screws. The board thickness of the M4 fixing parts is 6 mm. For the screw fixing parts,
see the following dimensions.
Secure a sufficient engagement allowance (5 or more pitches recommended) to fix screws and bolts/nuts.
Positioning pins that match the sides of the main unit make it easier to mount the main unit.
1-4-2. Checking the target measurement object
The following figure shows the length measurement direction of the equipment. Length cannot be measured in a
direction vertical to the length measurement direction.
The measurement distance of the equipment is based on the sides of the unit.
Install the main unit so that the measurement distance is 70 mm to the side of the unit.
If vibration is expected to occur on the target measurement object, tolerate the measurement distance within ±15 mm.
* The measurement distance adjustment tool makes it easier to adjust the measurement distance or install a thin
measurement object.
See the section for the optional measurement distance adjustment tool.
Hole position tolerance: ±0.15 mm
