(Note) Highly reflective objects can result in incorrect detection by causing out-of-range measurements.
(*1) Beam size: The beam size is defined by 1/e
2
(13.5%) of the strength of the beam at the beam center
(measured value).
Incorrect detection may occur if there is light leakage outside the defined spot and the material around
the sensing object is more reflective than the sensing object.
(*2) Resolution: The resolution is the deviation (±3
σ
) in the analog output when connected to the ZX2-LDA
Amplifier Unit. (The resolution is measured with the standard reference object (1/4
λ
flat mirror), at the
measurement point when the response time of the ZX2-LDA is set to 128 ms.)
The resolution is given at the repeat accuracy for a stationary workpiece, and is not an indication of the
distance accuracy.
The resolution may be adversely affected under strong electromagnetic fields.
(*3) Linearity: The linearity is given as the error in an ideal straight line displacement output when measuring
the standard reference object.
The linearity and measurement values vary with the object being measured. F.S. is the entire
measurement range.
(*4) Temperature characteristic: The temperature characteristic is measured at the measurement center distance
with the Sensor and reference object (OMRON’s standard reference object) secured with an aluminum jig.
(*5) Categorized as Class 1 by IEC60825-1 criteria in accordance with the stipulations of the FDA standard
Laser Notice No. 50, and registered with CDRH (Center for Devices and Radiological Health) (accession
number: 1020665)
