The newest generation of IO-Link sensors

With the HRTR 46B TEACH, Leuze electronic has developed a new sensor which enables electronic adjustment via teach in and IO-Link and thus configuration and diagnostics in the process.

Scanning ranges and corresponding parameters can now be adjusted in millimeters directly from the system control. Electronic configuration of the scanning ranges simplifies and accelerates system start-up and enables easy restoration of device characteristics after sensor replacement.

In addition, it leads to high system flexibility, since, for example, format conversions can be done quickly and automatically. Furthermore, versions with 2 individually adjustable switching points offer attractive solutions for 2 point regulations.

Information on electronic scanning range adjustment

Electronic scanning range adjustment in the teach sensor of series 46B is realized via an innovative, site-sensitive detector. This semiconductor component developed by Leuze electronic combines photosensitive receiver structures and logical evaluation functions in one chip. Moving parts in the sensor are no longer required. A new, patented evaluation algorithm ensures very robust behavior even with glossy or extremely dark objects as well as with interference light. In addition, detection reliability is increased in the new HRTR 46B TEACH reflection light scanner, since in comparison to the differential signal of standard scanners, more evaluation signals are available. Furthermore, the HRTR 46B TEACH sensor offers even more interesting options: Depending on the device generation, two individual scanning ranges can be set, for example, which are output via two switching outputs. Therefore, even demanding solutions such as two point regulations or the query of two distance values can be realized with just one sensor.

Information about IO-Link

The objective of the IO-Link interface technology is the consistent communication from the system control to the sensor-actuator level. In the past, in the case of a format change in the system, for example, the scanning range of the sensors had to be manually adjusted, or several scanners had to be used for multiple detection tasks. Electronic adjustment of the scanning range in connection with the IO-Link interface now allows the adaptation of sensors to modified process parameters via the control. In addition, with the uniform interface and intelligent sensors as IO-Link devices, additional information such as messages about detection reliability, contamination and much more can be directly called up and used to improve system performance.
