High-performance Multi-unit Laser Displacement Sensors
CD5 Series
Next level integration of accuracy, stability, and operability
- Highest-in-class repeat accuracy and linearity
- 3 CH multi-calculation function is possible
- Measurement is possible using only the sensor head
Featuring superb linearity of ±0.05% of F.S.*
Can be used to perform stable measurement of various types of workpieces.
Highest-in-class repeat accuracy and linearity
Superb linearity of ±0.05% F.S.* (catalog specifications, target workpiece: white ceramic). CD5 Series also can be used on materials for which stable measurement can be difficult such as SUS and black rubber, and provide a smooth linearity curve.
Measurement is possible using only the sensor head 
The sensor head features a built-in displacement measurement function. Measured value output by way of RS-422, as well as laser OFF input/ synchronous input can be controlled without use of an amplifier unit.
3 CH multi-calculation is possible!
Up to three sensor heads can be connected to one amplifier unit.
By sending measurement data at high speeds, multi-point measurements such as for thickness, height difference and parallelism can be performed using one amplifier unit.
Various sensor heads for different measurement applications
Achieving measurement stability through the newly developed “Tri-CORE” Technology
Employs digital sub-pixel processing
True receiving light waveform recognition
Digital sub-pixel processing that performs recognition with 65536 areas per pixel is newly employed. By obtaining a true receiving light waveform, a linearity that is up to twice that of conventional models can be achieved.
Thanks to high resolution electric shutter
Automatic level correction
In addition to featuring electric shutter control with a sampling period of 1/485, receiving light waveforms of a fixed height can be obtained for almost any targets, resulting in a reduction of errors between materials.
For objects with uneven surfaces, colors, and glossy or matte surfaces
Original algorithm 
This unique algorithm consistently identifies true peak position even in the case of receiving light waveforms that are stretched to the far side such as in the case of semi-transparent objects, as well as near-peak received light waveforms that become disturbed due to hairline.
By one sensor head
Reliable glass thickness measurement
(In specular mode of CD5-L☐ and CD5-☐30/-85)
Using one sensor head, it can provide highly accurate and stable measurement of glass thickness by simultaneously measuring the front and rear surfaces.
Newly developed sensor head specially designed for high-accuracy measurement
Next level balance between accuracy, speed and sensitivit
High sensitivity linear image sensor
A high sensitivity linear image sensor is employed to capture reflected light from workpieces both with high levels of speed and accuracy. It features 5 times improved accuracy and 10 times increased speed when compared to conventional models.
Low light aberration
“Multi-CLD” lens
The high-accuracy Multi-CLD receiving lens forms highly accurate images from reflected light using a linear image sensor. Using advanced focusing technology in which a camera is also employed, spot distortion caused by errors is significantly reduced.
Multi-CLD: Multi-Combined Low Dispersion
Processing measurement results with high levels of speed and accuracy
High speed processing unit
A high speed processing unit for CD5 series models embedded within the sensor. This enables data obtained from the linear image sensor to be instantaneously corrected and optimized before being output as measured values. With this, we have succeeded in enabling highly reliable measurement results to be obtained with both high levels of speed and accuracy.
Enhanced moving resolution
Wide type
A spot light wide-type that doesn’t rely on the surface of measurement targets is now available (CD5-W☐☐). By the results averaged in the widebeam, influences from unevenness are eliminated and highly accurate and stable measurements can be performed.
Eliminates malfunctions even when spot light overlaps
Cross-talk prevention
Cross-talk prevention enables stable measurements to be performed with high accuracy even if spot light overlaps or sensors are close together. Measurements can be performed correctly even for small warpage and tilting of workpieces.
Note: Sampling period will be six times longer.
(up to 2 units)
Even in water-filled areas
Featuring IP67 level water-resistance
These sensor heads feature a degree of protection on IP67. This means that they can be used without worry in factories or with devices in which contact with water occurs. Extension cables and connectors also feature a IP67 protection, meaning additional countermeasures for water resistance are not required.
Note: Water or oil that adhere to the optical surface could cause light to refract and prevent measurements from being performed correctly.
All-in-one amplifier unit featuring both usability and visibility
High-speed multi-point measurements using one amplifier unit
3ch multi-calculation function
Up to three sensor heads can be connected to one amplifier unit. By sending measurement data at high speeds, multi-point measurements such as for thickness, height difference and parallelism can be performed using one amplifier unit.
Easy setup
Setting wizard
Setup of basic sensor head parameters and calibration can be performed easily and interactively using the numeric keypad and display.
Can be used on various types of production lines
16ch bank function
This series is equipped with a 16ch bank function that communicates using through amplifier unit button operation or RS-232C, and that can have its setting switched (recall) to receive external signals from PLC, etc. This eliminates time wasted when changing setup of multi-product lines.
Convenient for sorting of workpieces with various sizes
Five comparator outputs
These models are equipped with five comparator units for which setting of upper and lower limits is possible. This is an extremely convenient function for sorting workpieces of various sizes or identifying various types of workpieces.
Multiple interface function with excellent expandability to PCs or PLC connections
Further extend cost savings
Up to three sensor heads can be connected
Up to three sensor heads can be connected to one amplifier unit. This eliminates the need to purchase more amplifier units when increasing the number of sensor heads and further extends cost savings.
Checking of waveforms without a PC or external monitor
Receiving light waveform monitoring function
These models are equipped with a receiving light waveform monitoring function that can detect whether lasers are emitting light to the workpieces at the optimal angle. Fine light axis adjustments can also be performed quickly and easily.
Assists in operations such as setup
Numeric keypad with pilot LED function
These models are equipped with Optex FA’s original numeric keypad with pilot LED function.
With lights that guide every time buttons are pressed during operation, even inexperienced users can perform operations easily.
Operations by one amplifier unit even for remote lines
Extendable up to 50 m
Extensions of up to 50 m in length are possible between sensor heads and the amplifier unit (longest in class). This means that unified operations can be performed even for remote lines using one amplifier unit.
Easy remote operation from PCs
Standard-equipped with a USB port
These amplifier units are equipped with a USB port that enables remote operation using a PC.
And, because a COM port is also equipped, connection to PCs and PLC, etc., is also possible.
Suitable for a wide range of needs
All sensor head types can be connected mixed
Any type of sensor heads can be connected to the amplifier unit. This means that thickness measurements can be performed on the workpiece by short-range heads while deflection measurements are performed by long-range heads. Also, sampling speed will not decrease even if three sensor heads are connected.
