optoNCDT 1220: New standard for industrial automation

The optoNCDT 1220 from Micro-Epsilon is a laser sensor with an attractive price/performance ratio, high measurement accuracy and ease of use. Suitable for OEM and serial applications in automation technology, this miniature sensor with integrated controller measures displacement, distance and position on a wide range of surfaces.

The optoNCDT 1220 laser triangulation sensor from Micro-Epsilon sets new standards in displacement and distance measurements in industrial automation. This powerful sensor provides high precision measurement results with a measuring rate of 1 kHz. The Auto Target Compensation (ATC) feature enables reliable control of the distance signal regardless of target color or brightness. Immediately ready to use, the sensor can be easily integrated without having to make any further settings. An intuitive web interface enables set up and configuration, if required.

Its compact design with integrated controller allows for the sensor to be integrated simply into plant, equipment and machinery, even where installation space is restricted. Moreover, its excellent price/performance ratio makes the sensor ideally suited to OEM and serial applications. Measured values are output as an analog signal. Primary application areas for the new laser sensor are found in automation technology, e.g., machine building, electronics and 3D printing.

confocalDT IFS2405-6: Measure precisely from a safe distance

The new, confocal chromatic confocalDT IFS2405-6 sensor is used for high precision displacement and thickness measurements on diffuse, reflecting and transparent materials. The new model completes the IFS series with a measuring range of 6 mm. The complete confocalDT IFS series covers measuring ranges from 0.1 to 30 mm.

In critical environments, the sensor can be mounted at a safe distance from the target due to the high offset distance of 63 mm. Therefore, the IFS2405-6 sensor is ideally suited to measurement tasks in the glass industry. High resolutions of 18 nm enable the measurement of thin layers from 300 µm. Furthermore, the IFS2405-6 tolerates tilt angles up to ± 10°. High sensitivity enables measurements even on dark surfaces.

Measuring on a non-contact basis, confocal chromatic sensors exert no influence on the measurement object. They provide long-term stability and measure to sub-micron accuracies. All IFS sensors and confocalDT controllers from Micro-Epsilon are inter-compatible.

Monitoring metal sheet infeed during the pressing process

In cold forming processes, deep drawing is considered a decisive step in the production process. optoNCDT 1420 laser triangulation sensors measure the metal sheet infeed during pressing, as this parameter is crucial for the quality assessment of the process. Due to their robust design, these sensors are insensitive to shock and vibration. Based on innovative sensor technology, the measured results are constantly precise even under challenging conditions such as parts with different reflection characteristics.

A tool punch presses the plate to be formed into the mold (die). The flange of the sheet is partially pulled inwards because the thickness of the component decreases as a result of the deep-drawing process while the displaced material flows from the edge of the sheet. This distortion can be detected as a change in distance. This value is crucial for the quality assessment of the pressed part.

The measurement of the distortion is carried out using several optoNCDT 1420 laser triangulation sensors, which are placed around the metal sheet, either in the tool or on the side of the tool. Due to their extremely compact design, these sensors can be effortlessly integrated into a small space. The arrangement is chosen in such a way that the laser beam measures on the edges of the sheet, which is between the top and bottom of the tool. Due to the extremely small measurement spot size, the laser is able to measure extremely tight gaps between the two tool parts of less than one millimeter.

The measured values are transmitted via analog or digitally to the controller. They allow a conclusion to be drawn on how much material has flowed. This enables, for example, the pressing force to be controlled during the ongoing process, reducing waste, material consumption, downtime and costs.

Even when exposed to harsh ambient conditions, laser triangulation sensors from Micro-Epsilon provide reliable measurement results. They are rugged and can withstand high mechanical loads such as vibration and shock. The Auto Target Compensation (ATC) feature rapidly compensates for different reflections caused by high-gloss through to dirty-matte sheet metal parts, while enabling a smooth distance signal.

Edge detection of fabric strips in cutting machines

When cutting fabrics, optoCONTROL CLS-K fiber optic sensors from Micro-Epsilon determine the exact position of the fabric strip. Therefore, a sensor is mounted directly on one of the cutting blades and recognizes when the fabric is in the cutting position. The fiber optic sensors used optimize the cutting accuracy and the quality of the final products, while reducing waste and machine errors.

The fabrics to be processed are around 0.5 mm thick, consist of various types of material and are partly perforated. In order to achieve an optimal result when cutting, the exact material position in the cutting machine must be determined before further processing. If the position of the material web is not determined or is recognized incorrectly, this can result in waste from faulty cutting and machine malfunctions due to missing controller signals.

Therefore, the optoCONTROL CLS-K31 fiber optic sensor from Micro-Epsilon is used for position detection. The measuring process is carried out at feed speeds of 20 m/min. Therefore, the sensor is mounted directly on one of the cutting blades and recognizes from a distance of around 140 mm when the fabric is in the cutting position. A switching output (PNP) then transmits a signal level directly to the controller and the cutting process begins. In this way, the cutting elements can be positioned exactly to 0.5 to 2 mm depending on the material. After each cut, the fabric position is recalculated.

The optoCONTROL CLS-K-31 measuring system from Micro-Epsilon provides highly reliable and reproducible measurement results.

The CLS-K-31 is virtually insensitive even to scratches and contamination on the shiny metallic surface of the roller while enabling exact cutting, increasing the product quality, and reducing waste and disturbances at once. Due to a wide portfolio of different fiber optics, freely-selectable lengths and numerous probes, individual solutions can be implemented, tailored to the customer’s requirements. The spatial separation of measurement and evaluation enables space-saving solutions with optimal integration possibilities.

New draw-wire displacement sensor for industrial serial applications

Designed for applications involving high volumes, the new wireSENSOR WPS-Kxx draw-wire displacement sensors measure distance and position precisely. The K series combines high performance sensors for indoor and outdoor applications with an excellent price/performance ratio. Due to their modular design, the sensors can be adapted quickly and easily to the respective measurement task.

Specially designed for industrial purposes, Micro-Epsilon launches the new wireSENSOR WPS-Kxx draw-wire displacement sensors with measuring ranges of 2300 mm and 5000 mm. This sensor series is ideal for precise distance and position measurements and primarily used in mobile machines, mobile cranes and the lifting technology.

The compact K series stands out due to its high flexibility and excellent price/performance ratio. Therefore, the sensors are particularly suitable for OEM and serial applications. Their glass fiber-reinforced plastic housing, as well as separate drum and spring spaces, make these sensors extremely robust against external influences in both indoor and outdoor applications.

The high degree of modularity enables easy adaption to different requirements in an efficient way. Customized versions with different measuring ranges, wire thicknesses and outputs are possible.
