The new HRTR 46B TEACH opto-sensor from Leuze electronic is innovative because it provides electronic adjustment using either the traditional teach-in method or across IO-Link with its two individual switching points and outputs providing two sensors in one housing.

The scanning range and corresponding parameters of Leuze’s latest sensor can be adjusted in millimetres directly from the PLC using IO-Link, which simplifies and accelerates system start-up, plus providing easy restoration of device characteristics should a sensor need replacing.

This highly flexible sensor can be used for example to provide quick and automatic format conversions or two-stage positioning, with the two individually adjustable switching points offering simple and therefore low cost solutions.

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 a single chip and therefore there are no moving parts.

A new, patented evaluation algorithm ensures very robust behaviour 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.

Information about IO-Link

The objective of the IO-Link interface technology is the consistent communication from the system control to the sensor or 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.
