Utilize Narrow Spaces in
The 24 × 24-mm Sensor Head fits easily into
essentially any machine.
Mounting area Reduced to
With traditional triangulation, it was necessary to use either diffuse
reflection or regular reflection depending on the material. However, the
confocal principle used for the ZW Series eliminates the need to change
the Sensor installation even if the material changes.
Non-contact Flatness Inspection of HDD
Stable Measurements for Any
Material with Superior Angle Characteristic
Stable Measurements from
the Same Mounting Position Even for Different Materials
There is no need to change or tune the
Sensor for each material. Even if the material changes, you can continue
to achieve stable measurements with the same Sensor from the same mounting
When measuring an object that has a
mirror-like surface with traditional triangulation, performance is greatly
reduced depending on the angel of the Sensor. When many Sensors are used
for height control during glass conveyance, the angles of the Sensors must
be adjusted with high precision during setup. The confocal Sensor ZW
series enables high-resolution measurements without strict angle
adjustment. This results in reduction of cost and space for the adjusting
jig and time for adjustment.
Robust Sensor Head Structure
Not Affected by Noise
Reduced Work for EMC Countermeasures
To ensure high-resolution measurements with
normal sensors, countermeasures must be implemented to protect the sensor
from he electromagnetic noise that is emitted by any nearby devices. The
ZW-series Sensor Heads, however, contain no electronic parts to enable
stable measurements even near power sections. Also, the Fiber Cable that
connects the Sensor Head to the Controller can be placed near power lines
or other cables that emit noise without affecting operation.
No Noise Emission
No electronic parts are used in the ZW-series
Sensor Heads or Fiber Cables, so they give off no electromagnetic noise.
You can therefore use them reliably together with other devices.
Reduced Work in Thermal
In high-resolution machine control, the heat
generated by a sensor head can adversely affect nearby equipment and cause
the error to increase. The ZW-series Sensor Heads, however, generate no
heat and therefore do not affect nearby equipment. You can also install
many Sensor Heads side by side and still be sure of reliable operation.
No Electronic Parts
Reduced Maintenance Costs
Displacement sensors are often installed in
moving sections and other locations that are subject to vibration. It is
important that they can withstand this type of requirement. The ZW-series
Sensor Heads consist of only the lenses and fiber. They contain no
electronic parts or PCBs. The number of parts in them is greatly less than
for a traditional sensor that uses triangulation, and this greatly reduces
the maintenance frequency. Also they use LEDs as the source of light, so
the safety measures that are required for lasers are not necessary either.
