ZX Series (ZX-L-N) Smart Sensors (Laser Type) 3
Specifications
■ Sensor Heads (Reflective)
Note: Highly reflective objects can result in incorrect detection by causing out-of-range measurements.

Beam shape Spot Line
Beam size*1
*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.

Resolution*2
*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.

Linearity*3
*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.
