Omron ZX2 Manual

Smart Sensors Laser Sensors CMOS Type
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.

Features
Stability
Measurements to a Precision in the Order of 10 µm for any Workpiece
Stable measurement even for changes in colors and materials or for moving
workpieces with CMOS that has a dynamic range of two million times
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.

Stable measurements on moving objects
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.

* 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.
