ZW-8000 / 7000 / 5000 Series Features 4

Mirror surfaces (inclined or curved surfaces)

Omron's, unique, white light confocal displacement sensor provides higher resolution measurements of angled or curved and shiny surfaces than traditional laser displacement sensors.

ZW-8000 / 7000 / 5000 Series Features 5

Transparent objects

The ZW-8000 Series can measure the top and bottom surfaces of a thin transparent sheet or film by separating the light reflected from both surfaces, which is difficult with conventional laser displacement sensors.

ZW-8000 / 7000 / 5000 Series Features 6
ZW-8000 / 7000 / 5000 Series Features 7

Minute objects

Thanks to its very small spot diameter, the ZW-8000 Series can measure targets on minute objects extremely precisely, which is impossible with a conventional laser displacement sensor with a large spot diameter.

ZW-8000 / 7000 / 5000 Series Features 8

A variety of sensor heads with a small spot diameter to suit your measurement conditions

Shape

Using conventional sensors, the measurement accuracy can be achieved by increasing the averaging times, but downside is that this lowers the profile reproduction accuracy. The ZW-7000 acquires a sharp profile by sampling as fast as 20 μs without averaging, solving this issue.

ZW-8000 / 7000 / 5000 Series Features 13

Flatness of coarse surfaces *5

Our white light confocal displacement sensors can provide accurate flatness measurement by tracing an object once without being affected by its excessive reflection, the sensor head direction, nor the material hairline direction, which are difficult to track with a conventional laser displacement sensor.

ZW-8000 / 7000 / 5000 Series Features 14

Note: All measurement graphs represent typical examples. Measurement may be affected by the shape or material of the object being measured.
Before final installation, test the sensor required for the application to validate that the desired measurements have been obtained.

[Sensor head] A wide sensor head offering for diverse integration requirements

New ultra-small sensor heads make integration more flexible

The continued evolution of products as they have become thinner, more curved, and more compact has meant that the inspection process has also become more diffcult, and this has necessitated visualization and assembly control in the upstream assembly process.
In response to this, Omron has developed a lineup including both square-shaped type sensor heads with long measurement distance, and ultra-small pen-shaped type (straight or right angle) sensor heads that can be installed in narrow spaces.

[Usability] Reduce production cycle times through efficient arrangement and movements

Save Time and Money: No need to rotate the sensor

A conventional laser displacement sensor measures the height of an object based on the position of the spot on the receiver.
The machine requires an extra step to rotate the sensor according to the object shape or moving direction.
Our white light confocal displacement sensor can measure from the same installation position while moving in any direction, with no restriction on installation direction.

ZW-8000 / 7000 / 5000 Series Features 27

Flexible fiber cable for easy installation

The controller connects to the sensor head through a 3 mm diameter flexible fiber cable.
The cable has cleared a bending test consisting of 3,000,000 repetitions*2 for reliable application on moving parts.

*2. Omron's bending test condition: 3,000,000 bends to a 20 mm bending radius

ZW-8000 / 7000 / 5000 Series Features 28

Easy wiring for moving measurements

No preamplifiers or optical parts are used in the fiber cable, which makes it easy to route the cable through a cable carrier or protective conduit for moving measurements.

ZW-8000 / 7000 / 5000 Series Features 29

Extension cables for large machines

A 30-m extension fiber cable can be used to extend the distance to up to 32 m, supporting a flexible wiring in a large machine.

ZW-8000 / 7000 / 5000 Series Features 30

Compact fanless controller

The compact sensor controller, which integrates the optical unit including the light source and spectroscope, can be mounted on a DIN track, saving space in a control panel.
The fanless structure can be used in cleanrooms for manufacturing semiconductors and electronic components.

ZW-8000 / 7000 / 5000 Series Features 31

Increase throughput: Simultaneous measurements can be achieved using multiple sensor heads

Space restrictions prevent side-by-side installation of many traditional laser displacement sensors. The pen-shaped straight sensor heads can be installed close together to obtain multiple measurements at once, instead of measuring one at a time, thus reducing measurement time.

ZW-8000 / 7000 / 5000 Series Features 32

Further Benefits of White Light Confocal

No discrepancy in the measurement point

With a traditional laser displacement sensor, the measurement position and spot size vary with the height. This means there are times when the position cannot be measured with high resolution due to warping and inclination. With a white light confocal displacement sensor, the measurement point remains the same at any position in the measuring range so that precise measurements can always be made.

ZW-8000 / 7000 / 5000 Series Features 34

Measurement in narrow area and by the wall

When a traditional laser displacement sensor measures the inside of a narrow tube or the height of a small depression, the wall often obstructs the reflected light, and the orientation of the sensor and object must be adjusted many times. A white light confocal displacement sensor can measure the points in narrow spaces or small objects, without changing its installation orientation, because the emitted light and reflected light are positioned along the same axis.

ZW-8000 / 7000 / 5000 Series Features 35

[Usability] Reduce setup and tuning time

Reduced work - EMC measures and thermal design are not required

The sensor head contains no electronic parts and indicators that generate noise and heat.
The sensor head design maintains stable operation in installations with electronic or magnetic noise.
Devices in close proximity and measurement values are not affected by noise or heat from the sensor head.

[Patent pending] Multi-point scaling for stable measurements

The ZW Series measures up to 10 points to minimize measurement errors. *1
Even when the sensor head is installed at an angle or measures objects through glass, stable measurements can still be achieved, which is difficult with conventional 2-point scaling.

ZW-8000 / 7000 / 5000 Series Features 41

*1. Supported on ZW-8000 Series

No laser safety measures required

A white light source *2 eliminates the need for safety measures around the machine and safe use training for workers that are required for a laser light source.

Previously safety measures or laser were required

When a laser displacement sensor was used, a shield around the machine for safety was required and workers had to be trained for safe use.

ZW-8000 / 7000 / 5000 Series Features 43

*2. The ZW-8000 Series is categorized as Class 1

[Patented] Calibration ROM ensures compatibility and precision

The sensor controller is compatible with sensor heads, which enables quick replacement and saves costs. Each sensor head has its own calibration ROM that is used to load calibration values into the sensor controller, providing compatibility and high-precision measurements.

ZW-8000 / 7000 / 5000 Series Features 45

Stable measurement of multi-layer objects possible with advanced function “EdgeTracks” *2 [Patent pending]

When measuring objects with multiple layers, the white light confocal displacement sensor can stably measure target edges even if the object rattles and certain of the edges cannot be measured.
