ZX2

Stable measurement that is unaffected by

workpiece changes.

The simple setting for everyone.

• High-precision measurement to approx. 10

μm.

• Stable measurement regardless of movement or changes in

workpiece color or material.

• Smart tuning for optimal setting with one button for essentially any user.

• The 11-segment display enables reading characters at a glance.

• Four built-in banks make changeovers easy.

• Stable measurement in harsh environments with IP67

protection for Sensor Head and robot cable.

• Laser life indicator to prevent line stoppage through visualization.

Stability

Measurements to a Precision in the Order of 10 µm for any Workpiece

PAT.P

The use of a unique OMRON HSDR-CMOS (high-speed and dynamic range) image sensor

and a step-less laser power adjustment algorithm enable stable measurements for any

color or surface conditions, from metals to substrates, rubber, and transparent objects.

Linearity of 0.05% F.S.* achieves a measurement precision in the order of 10 µm.

A line beam is used in addition to an emitter beam when dealing with rough surfaces to average out the

amount of reflected light and to offset the amount of light received at a high-speed measurement period of

30 µs in order to reduce variations in received light and to enable stable measurements for moving objects.

Stable measurements on moving objects

* Linearity: The maximum error that occurs for measurements within the measurement range.

A linearity of ±0.05% F.S. means that when the LD50L is used for a measurement range of 40 to 50 mm,

the maximum error within the measurement range will be 10 µm.

the SMART button

Essentially Anyone Can Set Optimum Conditions

Easily select smart tuning

with one button.

PAT.P

The optimum settings for stable measurement can be achieved with one

smart tuning button. The settings will not rely on the skill of the user.

Three selectable tunings

More accurate settings are made possible by the three tuning

methods for different workpiece types and surface conditions.

Single smart tuning

Best configuration for stable detection

in case of objects do not change by

pushing the button for one second

Multi-smart tuning

Ideal configuration for stable detection

of changing objects by pushing the

button for three seconds

Active smart tuning

Continuous configuration improvement

for the stable detection of all locations

by pushing the button for five seconds
