efector dualis type O2D

All geometries in focus.

The electronic eye.
The application possibilities of the contour sensor efector dualis range from presence, position and orientation monitoring via sorting and counting tasks to quality control.
With an intuitive step-by-step interface and good / bad parts the user can simply create a model of the object to be recognised. The recognition software compares the object with the stored ideal, regardless of orientation, and transmits the results (good or bad, position, orientation) to the higher-level PLC.
The sensor can manage up to 32 separate tasks with a maximum of 24 models each.

efector dualis type O2V

Checking variable features of objects

Whereas common vision sensors check parts on the basis of defined contours (like the contour sensor O2D) the new O2V pixel counter compares on the basis of variable features.
Instead of a defined contour the user determines relative features used by the sensor to assess an object or a scene. Within freely selectable tolerances the sensor determines features such as area, size, roundness or compactness of an object.

Pixel counter:

o2dComparable to a counting frame or slide rule, the O2V vision sensor counts all pixels of the areas of identical greyscale values of an image. Furthermore, it can group accumulations of certain grey-scale values to individual objects and assess by different criteria.

Multicode reader type O2I

Reliable identification of 1D and 2D codes.

Powerful identification.
In addition to the Data Matrix code ECC200, the ifm multicode reader handles further 2D and 1D codes. Reading is not dependent on the orientation of the code to the sensor. Even damaged or soiled codes are reliably identified, even if 28 % of the information has been damaged. The professional software of the multicode reader takes the high reading reliability of the Data Matrix code to a new dimension. Top choice for price / performance: The multicode reader provides high functionality and performance at the price of a sensor.

A wide range of applications.
There is a wide range of applications for the multicode reader in industry. Its applications include product tracking, product control and product identification.

Optimum illumination.
In addition to an automatic exposure setting, manual adjustment is also possible. Four illumination segments can be deactivated and activated manually. So optimum results are achieved even with highly reflective metal surfaces.

o2d Today bar codes are widely used and can be understood as font styles to be read from right to left. 2D codes encode the information in the area. Similar to a domino puzzle, unambiguous information is conveyed which is read by the O2I vision sensor.

efector pmd 3d type O3D

The third dimension at a glance.

With the 3D sensor, the measurement of distances from irregular surfaces is no longer a challenge. 3072 precise distance values replace a multitude of standard photoelectric sensors. efector pmd 3d also is a clever alternative to ultrasonic sensors, optical distance sensors or laser scanners. In the application example on the left a missing bottle in the crate triggers a switching signal.

Irrespective of the distance between sensor and object, efector pmd 3d determines the volume of any object. The sensor moreover enables subdivision of the field of view into separate windows. Areas of no interest can be ignored and relevant areas can be inspected in detail. Up to 64 windows can be monitored for the same adjustable threshold.

The sensor determines the level above the previously defined background in the search zone. The shape of the bulk material does not matter.

Field of view size [mm]
Operating distance [mm]
Award winning:
The first industrial 3D sensor that detects objects in three dimensions at a glance. The sensor operates on the principle of time of flight measurement based on PMD technology.
The resolution of 64 x 48 pixels results in 3072 distance values per measurement for the detailed assessment of the application.
Illumination, time of flight measurement and evaluation are integrated into an industrially compatible housing.
Switching outputs and analogue outputs for the simple integration into the control environment.
Far sight:
Range up to 6.5 m, robust against extraneous light.

3D sensor:

o2dSimilar to a bed of nails, the O3D 3D sensor scans the current scene in depth. These more than 3000 measured distance values can be used to create a multitude of virtual sensors, for example to check that a crate is complete with any kind of bottles.

Vision sensors from ifm electronic.

Powerful like a camera system, simple like a sensor.

In automation technology visions sensors are today an integral part of assembly, production and quality control and last not least increase efficiency. They are cameras with application-specific evaluation, i.e. reliable electronic eyes at low cost with a high degree of integration.

From the camera to the sensor.

A few years ago high-price camera systems were needed. Due to technical developments and continuously falling prices for components ever more intelligent functions could be implemented at low cost in an ever smaller space. Compact vision sensors not only replace camera systems but also offer additional application options. For the variable position detection of objects or scenes they replace, for example, complex proximity sensors or multiple sensor solutions such as sensor bridges, when pallets or crates are monitored for completeness.

Easy to integrate.

One of the distinguishing features of vision sensors is their simplicity. Whereas image processing systems can usually only be integrated into the production process by qualified personnel or cost-intensive external integrators, vision sensors can be used without previous knowledge due to their application-specific nature. Easy “parameter setting” instead of complex “programming” is the motto. Ready-to-use function blocks support the integration into the PLC. An Ethernet process interface is used for data transmission, parameter setting and remote maintenance. Also, all units have switching outputs to signal successful testing. So vision sensors offer the same ease of use as binary sensors.

Robust and compact.

Another advantage: Due to their high protection ratings and wide temperature ranges ifm vision sensors can in the truest sense of the word be brought very close to what is actually going on. They are also distinguished by a particularly high degree of integration. In contrast to complex camera solutions, all necessary components such as illumination, optics, evaluation and output logic are integrated into the industrially compatible housing. Tasks such as quality control, monitoring completeness or reading 1D and 2D codes can easily be performed at low cost using ifm vision sensors.
