With the HL-D3 measurement sensor heads, you can choose one of four sensing modes to cater to a variety of measurement needs, including high-speed sensing in production lines and high-precision detection at workstations outside production lines.
Multi-select displacement sensing The displacement sensor senses up to 10 measurement points specified on the X axis and completes the judgment at super-high speed. Whole synchronized measurement The displacement sensor performs sensing of all target objects with the same sensitivity adjustment throughout the entire width measurement range (X axis). This mode is suitable for the sensing of fast-moving objects. Multi-zone beam control High-precision sensing is achieved by segmenting the width measurement range (X axis) to optimize light intensity. This mode is suitable for the sensing of objects with varied glossiness or color. Constant pitch measurement Sensing is performed at even intervals upon adjusting the sensitivity per the pitch specified along the width measurement range (X axis). High-speed sensing is made possible by the reduced number of sensing points. The innovative optical system allows the HL-D3 to work with parallel beams. Parallel beams reduce the area of shadow that appears when light shines on the target object, thus making it possible to sense the shape of the target object more accurately than with non-parallel beams. |

The HL-D3 series calculates the shapes, including the height difference, width, and cross-sectional area, from the shape waveform based on the received light. At the same time, the displacement sensor uses these calculation results to instantaneously make High / Go / Low judgments based on the current upper and lower limits (only height calculation and step calculation are possible in multi-select displacement sensing mode).
Thanks to the fact that the sensor is equipped with two outputs, different shape calculations can be performed for each output. Alternatively, two sensor heads can be connected and every head has its own output. Shape calculation is performed using the representative values extracted from the calculation area specified by the set parameters. This technique has the benefit of tolerating shifts in the position of the objects to be measured as long as they are within the calculation area.

For easy parameter setup and monitoring of measuring and judgment results, install the software HL-D3SMI on a PC (compatible operating systems: Microsoft Windows® Vista Business 32 bit SP or higher, Microsoft Windows® 7 Professional 32 bit / 64 bit, Microsoft Windows® 8 Pro 32 bit / 64 bit) and connect the HL-D3C controller via a USB cable. The shape waveform based on the saved data can be reproduced on screen for further analysis.
Main screen (1) The main screen is where you set up the controller operations and the parameters and individual functions for the sensor head. Received light intensity image screen (2) Here you can check the light-receiving status of the 2D image sensor built into the sensor head as well as the shape waveform of the measured values.

Conventional 2D displacement sensors produce the measurement values of the specified points after sensing the entire width measurement range (X axis). This is unsuitable for high-speed sensing.
The HL-D3 series makes the processing more efficient by sensing only the displacements at the specified points. This feature enables super-fast measurement results from sensing to calculation and judgment. At each point the sensor also adjusts the sensitivity to ensure not only speed, but also high precision. Features
Wide-cell function When the surface is rough, such as with cut metal, sensing of a single point will result in errors due to the uneven surface. The wide-cell function expands the sensing points for the light receiving side and obtains the mean value (or maximum or minimum value, depending on the setting) to improve the stability of the measurements. |
Conventional 2D displacement sensors uniformly use the same light intensity adjustment for the entire width measurement range (X axis). When there are parts with significantly differing reflection properties, the received light intensity becomes saturated or insufficient, thus preventing the sensor from acquiring effective measurement results.
The HL-D3 series breaks down the width measurement range (X axis) into small segments and adjusts the emission for each segmented unit (called “light intensity adjustment unit”) for optimal sensitivity in order to achieve stable, high-precision sensing. This is called multi-zone beam control (MZBC).

Missing and loose screws can be detected by sensing the displacement of the screw head from the reference plane. The HL-D3 provides judges the sensing results as High / Go / Low judgment depending on the upper and lower limit you have set. When two sensing points are used, in-line testing can be performed with a sampling rate of 80μs. |
 |
The HL-D3 can even sense the tiny pins of surface-mounting components. The measured values can be managed by setting the reference plane and pins as sensing points. |

The HL-D3 can accurately sense the shapes of the thread and black insulation of a miniature bulb. |
