3D sensors

Rod4plus (Area sensor)

Rod4plus (Area sensor)

Contactless laser scanners for object detection and contour measurement.

A laser measurement beam is deflected by a rotating mirror and covers an area of 190° with a radius of up to 65 m. The measurement contour is output via Ethernet or a serial interface. In addition, there are models for object detection in up to four simultaneous detection fields.



  • Area scanning distance sensor for object detection and object measurement.
  • Detection fields up to 50m
  • 8 detection field pairs
  • Config-Plug for device exchange without PC
  • Fast Ethernet : ROD4 plus
  • Laser class 1


Light section sensors measure height profiles along a projected laser line. With these sensors, objects with high resolution can be detected quickly and reliably in 3D. Depending on the model, the function range extends from simply presence monitoring to edge measurement to 3D measurement of objects

Products for safety at work

As one of the technology leaders in the area of optoelectronic safety sensors for industrial automation, we offer effective personnel protection devices in accordance with international safety standards


The immense flexibility of the safety laser scanners ROTOSCAN RS4 is the result of the independent protective/warning field pairs, which can assume any field contours as well as the ability to change over between these pairs


The RSL 400 family of safety laser scanners comprises 16 device types in four staggered operating ranges and function variants. As a result, you can always select the best scanner at the best price performance ratio – if necessary, with a scanning range of 160 square meters thanks to a scanning angle of 270° and operating range of 8.25 meters. Whether mobile or stationary – the RSL 400 family covers all conceivable applications.




The 300 series MLC safety light curtains are the latest generation of extremely slim and robust type 2 devices with slightly set back front screen and reinforced side walls. The devices are available in the Basic and Standard versions, thereby fulfilling various requirements. They can be used universally, due to metal end caps, a flexible fastening concept and the option of form-locking installation. There are also variants which have an AIDA-compliant pin assignment.



The identification of bar codes, 2D-codes and RFID transponders is among our core competencies. Complemented by other identification systems, it is our broad product range of IDENT technologies that opens up maximum flexibility to our customers. Our products ensure absolute reliability and maximum system availability. Discover our world of IDENT products.







Data transmission /control components

In addition to the actual device technology, the transmission of data or the connection of the devices to a wide range of different fieldbus environments is becoming increasingly important and plays a decisive role in your system's ease of use and flexibility. Discover innovative connection concepts and universal configuration solutions that also reveal unexpected efficiency potentials
