*1. Beam size: The beam size is defined by 1/e2 (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 (±3σ) in the linear output when connected to the ZX-LDA Amplifier Unit.
       (The resolution is measured with the standard reference object (white ceramic), at the measurement point with the
       ZX-LDA set for an average count of 4,096 per period.)
       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.
*4. Temperature characteristic: The temperature characteristic is measured at the measurement point with the Sensor
       and reference object (OMRON's standard reference object) secured with an aluminum jig.
Note: Highly reflective objects can result in incorrect detection by causing out-of-range measurements.

*1. This value is obtained by converting the deviation (±3σ) in the linear output that results when the sensor head is
       connected to the amplifier unit, into the measurement width.
*2. For an average count of 64. The value is 5 μm for an average count of 32.
       This is the value that results when a minimum sensing object blocks the light near the center of the 1-mm
       measurement width.
*3. For an average count of 64. The value is 5 μm for an average count of 32.
*4. For an average count of 64. The value is 15 μm for an average count of 32.
