1 Making Industries Smarter The Next Generation of Photoelectronic Sensors
2 Sensors are the most important components of machines. Dr. Alexander Ohl Director of Development, wenglor sensoric Technology Communication Performance Functional Principles Designs Photoelectronic Next Generation stands for a new age of photoelectronic sensors. Intelligent, networked and learning sensory organs in automated industries are the key component of the future production sector all over the world. The intelligent and high-performance wenglor portfolio of sensor solutions provides the best conditions for making the vision of the Industry 4.0 a reality.
3 Smart Communication Speak and understand the language of industry Sensors from the // range are characterized by state-of-the-art communication capability. The latest IO-Link generation 1.1 offers high efficiency during installation and initial start-up of all products. Intelligent Data Transfer via IO-Link & wteach2 wenglor sensors communicate using an integrated IO-Link interface with all standard operating systems. Predefined settings can be easily copied from the controller to additional // sensors. Configuration and visualization is also simplified via the free wenglor software wteach2.

4 Condition Monitoring Via IO-Link, any additional information on the state of the sensor can be called up at time. This maximizes the benefit of preventative maintenance and, for example, maintenance interval planning and avoids production stoppages. // Sensors with IO-Link Using standards intelligently Fast Duplication The sensor settings can be saved easily and duplicated for Flexible Settings Predefined parameters can be transferred to the sensor during a product change, for example. This minimizes the time required for product changes. other applications. This makes the initial start-up easier and saves time. Data Storage All parameters are saved in the sensor as well as the IO-Link master. In the event of a replacement, the configuration is transferred automatically to the new device. This enables the device to be replaced easily with no programming required.
5 Performance in Series Innovative technologies for maximum precision Sensors not only offer extraordinary communication capability, but unique performance as well. High-quality components and parts guarantee precision and reliability in each individual sensor. From the hardware to the software, the // concept stands for high performance in all industry areas. No Reciprocal Influence In most cases, reciprocal influence is ruled out with // sensors. This makes installation possible in very small spaces and provides system designers with maximum flexibility. Insensitive to Ambient Light Even under the influence of modern LED lights, // sensors demonstrate extremely reliable switching performance. Balanced Light Spot Thanks to the balanced light spot with aligned optical axis, no subsequent re-alignment of the light spot is required. This makes both the initial start-up and the sensor replacement easier. Diverse Measuring Tasks Via the IO-Link interface, distance values can be read out, for instance, and measuring tasks carried out. Laser Class 1 All // generation laser sensors are available in laser class 1. This means that they are completely safe for the human eye, removing the need for warning signs and safety measures. Balanced Switching Point // sensors are set at the factory so that each sensor has the same switching distance with the same setting. This removes the need for time-consuming adjustments if a sensor is replaced.
6 The Physics of Light Non-contact object detection in five functional principles Sensors from the // generation are available in a total of five optical functional principles and can therefore be used for a wide range of applications. Reflex Sensors Reflex Sensors with Background Suppression Retro-Reflex Sensors Retro-Reflex Sensors for Clear Glass Recognition Through-Beam Sensors Reflex Sensors with Background Suppression Reflex sensors with background suppression work with red, laser or blue light according to the angle measurement principle and are designed to detect objects against any background. The object s color, shape and surface characteristics have practically no influence on detection range. Reliable object detection regardless of the object surface or background color Two independent switching outputs Laser (Red) Reliable object detection regardless of the object surface or background color Smallest parts can be detected thanks to the minimal light spot Two independent switching outputs Blue Light Reliable detection of dark shiny objects, such as solar wafers Reflex Sensors Reflex sensors work with red light according to the principle of energy and are designed to detect objects without a background. The switching distance is set for a given object. Note that: Bright objects reflect transmitted light better than dark objects. This means that, for example, dark (matte) objects can be differentiated from bright (glossy) objects. Reliable object detection without interfering background Visible red light for easy alignment High switching frequency for high-speed applications (Line) Detection for objects with holes (e.g. PCBs) thanks to line optics Reliable detection of moving objects on the light line
7 Retro-Reflex Sensors Retro-reflex sensors work with red or laser light and a reflector. If the light beam between the sensor and the reflector is interrupted, the output is switched. The visible light spot makes alignment and initial start-up easier. Even shiny objects such as mirrors, chrome plated or other reflective surfaces can be reliably recognized thanks to the integrated polarization filter. Reliable detection of reflective or shiny objects High switching frequency for fast processes Retro-Reflex Sensors for Clear Glass Recognition Where conventional retro-reflex sensors reach their limits, retro-reflective light barriers for clear glass detection ensure that extremely shiny objects like glass, PET bottles, trays or film can be detected. The dynamic readjustment of the switching threshold function automatically adjusts this for contamination, aging or temperature deviations, meaning that these factors have almost no effect on functionality. No blind spot via single-lens optics Reliable detection of transparent objects like Glass PET bottles Films Trays Through-Beam Sensors Through-beam sensors work with red or laser light as well as a transmitter and a receiver. If the light beam is interrupted, the output is switched. The transmitter can be deactivated using test input in order to test the functionality of the through-beam sensor. Thanks to their high light intensity, the sensors provide a high degree of operational reliability, even with interferences like steam, fog or dust. The good visibility of the light spot simplifies easy alignment and initial start-up even from a long distance. Reliable object detection in harsh environments thanks to great range Function test via test input prevents production downtime Laser (Red) Reliable object detection in harsh environments thanks to great range Precise detection of hair-thin parts via collimated laser Function test via test input prevents production downtime Extremely high switching frequency Laser (Red) Reliable detection of reflective and shiny objects High switching frequency for fast processes Collimated laser enables precise object detection Smallest parts can be detected thanks to the minimal light spot
