2D triangulation sensors (Laser Scanners)
RF620 Series
Application domain
The laser scanners are intended for non-contact measuring and checking of surface profile, dimensions, sorting and sensing of technological objects. The series includes 13 standard scanners (100 profiles/s for the full range) and 9 models of High Speed scanners (250 and 500 profiles/s for the full range)
Operating principle
Operation of the sensors is based on the principle of optical triangulation
Radiation of a semiconductor laser is formed by a lens in a line and projected to an object . Radiation scattered from the object is collected by the lens and directed to a two-dimensional CMOS-array. The image of object outline thus formed is analyzed by a signal processor, which calculates the distance to the object (Z-coordinate) for each point of the set along the laser line on the object (X-coordinate).

Performs simultaneous width and depth/height measurements in one cycle
Eight measurement modes available, including a combination of step, width and edge position
No work piece or sensor movement required: improves measurement precision and reduces measurement cycle time
Z500 performs all data processing and calculations, eliminates need for other controllers
Two-dimensional SW-CCD and multiple incident level control allow shape measurement of curved work pieces and a wide variety of other surfaces

O2DS Scanner measures where others give up - think of hot rolled steel.
The O2DS scanner is an optoelectronic unit for non-contact precision measurement in two dimensions, developed for 2D- / profile-measurement in all kinds of industrial applications.
The O2DS is a laser scanner of the Flying Spot type. The measurement is performed by oscillating the triangulation plane over an angel up to 50°. A fine focused/collimated laser beam is diffusely reflected from the surface of almost any kind of object, and a CCD-camera records the image through an objective.
The measuring frequency is 2 kHz. Different scanning angels can be combined with four different measuring ranges. The smallest range covers 80 to 180 mm and the largest 380 to 1080 mm. The smaller the measuring range is, the higher the resolution will be.
As well as the ODS sensors, the 02DS scanner can be delivered as HT (high temperature) models for measuring on objects with surface temperature up to about 1200°C. Used under such conditions, precautions must be taken to protect the scanner from the heat.
Scanners can furthermore be customized to other than standard scan angels and measuring ranges.

Cobra 2D is a portable laser scanning system that provides high resolution linear profiles. And since it uses low power laser light, it is ideal for fragile or pliable parts that have critical surface contours. It's quick and easy to measure height, length, slope, and radius.
Its Scan-X®software makes scanning easy. View and analyze scans for the dimensional information you need. The heart of the system is field proven DRS™ (Digital Range Sensor) technology, combined with accurate motor control, and data analysis software. Since Cobra 2D scans by moving the DRS sensor over the surface, no special fixturing is required. Cobra is portable. When used with a laptop computer, you can take it where you need it.

Cobra™ 3D is a non-contact measuring instrument capable of automatically acquiring a series of linear profiles in order to map an area for 3D analysis. 3D profiles provide important detail easily missed in a single linear profile. For example, the symmetry of a critical feature clearly shows in a 3D plot. Scanning an area also proves that the apex of a feature was scanned, an important capability not easily verified with a single linear scan.
Cobra 3D uses proven DRS™(Digital Range Sensor) laser technology to scan surfaces with up to 0.125 µm Z height resolution. Computer controlled motors move the DRS over the part while a precision stage translates the part beneath the DRS to build up a series of linear scans. Scan-X® analysis software controls the process and presents the results graphically and numerically.
The optional video camera makes setup even easier and provides live color imaging of the scanning process for visual verification of the scan location on the part.

LMC-M-M2D-LASER for Profile-Contour Scanning
The Scanner M2D provides 2-dimensional measuring of profile heights. The measured objects may consist of various materials. A laser line is projected onto the target and the distance to several points of the object is measured by triangulation. The Scanner is suitable for the geometric profile recognition and distance measurement. The height (Z-axis) by distance (X-axis) is measured. The result is the contour of the object at the point of measurement. Every 20 ms a complete scan of 283 points of measurement, or every 40 ms a scan with 566 points of measurement is done. The measurement range works from 5...1200 mm (X-axis) and 8...600mm(Z-axis).

Low profile lift tables, due to their low closed height, do not require a floor pit, offering flexibility of location and keeping installation costs to a minimum. It is possible to transport the table easily and in safety by a “mobility kit” from one work station to another providing an even higher flexibility in use.
Two versions are available, either full top platform or “U” shaped, which is particularly useful when loading a pallet safely onto the table using a hand pallet or pedestrian truck without the need for an access ramp.
Capacity from 500 to 2000 kg.
Our tables comply with the European Safety of Machinery standards EN 292, Machinery Directive 98/37/EC and Safety requirements for lift tables EN 1570.

In addition to offering all the safety features of our regular "Guardian" Series lift tables, our low profile models have a lowered height of only 3.25". The low profile feature provides greater flexibility since a variety of applications can be accommodated. And, installation costs are reduced since the need for a floor pit is eliminated.
With capacities ranging from 1,100 pounds to 3,300 pounds, the "Guardian" Series low profile lift tables are available in three versions with either a rectangular, "U" or "E" shaped top for numerous material handling applications.
The "U" shaped low profile table is ideal for handling wire baskets, containers and plastic and wooden pallets that have open bottoms. This design allows loading with either a manual or electric pallet truck without the need for a loading ramp.
The "E" shaped low profile table has all the features as the U-Lift and the other Guardian low profile tables. It is available in a 2,200 lb capacity. The advantage of the E-Lift is the center opening measures 28.9" which is ideal for a standard 27" wide pallet truck. The added center support of the E-Lift is designed to help prevent the pallet from deflecting downward in the center due to the wider center area. The center support is also shorter than the outside legs to allow easier access with the pallet truck. The E-Lift like the U-Lift is designed for use with open bottom pallets, skids, containers or wire baskets.
