Calculating unit
2. Beam size: Defined as 1/e 2 (13.5%) of the central intensity at the smallest value of diameter for the measurement range (typical value) False detections can occur in the case there is light leakage outside the defined region and the surroundings of the target object have a high reflectance in comparison to the target object.
3.
Resolution: indicates the degree of fluctuation (±3σ) of analog output when connected to the ZX2-LDA. (The measured value is given for the center distance for OMRON’s standard target object (diffuse-reflective models: white ceramic object, regular-reflective models: 1/4 λ flat mirror) when the response time of the ZX2-LDA is set to 128 ms.)
Indicates the repetition accuracy for when the workpiece is in a state of rest. Not an indication of distance accuracy. Resolution performance may not be satisfied in a strong electromagnetic field.
4. Linearity: indicates the error with respect to the ideal straight line of the displacement output in the case of measuring Omron’ s standard target object. Linearity and measured value may vary depending on target object. F.S. indicates the full scope of the measurement range. (ZX2-LD50 (L): 20mm)
5. Temperature characteristic: Value for the case the space between the sensor head and Omron’s standard target object is secured by an aluminum jig. (Measured at the measurement center distance)
*5 These Sensors are classified as Class 2 laser devices for diffuse-reflective models and Class 1 for regular-reflective models under EN 606825-1 and the regulations of Laser Notice No. 50 for FDA certification. CDRH registration has been completed for diffuse-reflective models and is scheduled for regular-reflective models.

HSDR-CMOS Image sensor
The ZX2 utilizes a newly developed High Speed & Dynamic Range (HSDR) CMOS image sensor. This provides stable measurement on surfaces ranging from highly absorbing to highly reflective, without loss of accuracy. The ZX2 continually monitors the received light level and adjusts the laser diode output to compensate, all in a cycle time of 60μs.
Easy Set-up
ZX2 Easy Set-up The ZX2 eliminates the need for complex set-up through lengthy parameter adjustment. A smart button is used to configure the sensor by defining the surface type for measurement.
- One type of surface
- Multiple surface types
- Highly reflective surfaces
Applications
Double sheet detection application
The high accuracy measurement and ability to cope with varying surface types, allows the ZX2 to be used for double sheet inspection.
Position reference application
Accurate linear measurements can be performed at high speed, allowing the ZX2 to be used for high speed position reference applications.
Thickness measurement application
Thickness measurement is made simple in the ZX2 via the calculation unit. Accurate thickness measurements can be achieved even on highly reflective surfaces.
Warpage measurement
Using multiple ZX2 units it is possible to inspect the warpage or deflection of components. Even where the temperature or measurement surface varies, stable measurements can still be achieved.
