New Generation of Photoelectronic Sensors Makes Industry Smarter

PNG//smart – this is the designation under which wenglor sensoric introduced a new generation of photoelectronic sensors (photoelectronic next generation) to the market at the beginning of October. In keeping with the motto “Making Industries Smarter”, intelligent sensors with five different functional principles were presented. Consistently equipped with IO-Link 1.1, they stand for thinking, networked, learning sensors for the future of Industry 4.0. The 1K miniature design was presented as the first representative of the product range.

IO-Link: Communication of the Future
All of the sensors included in this product range boast a unique combination of outstanding communication capabilities and photoelectronic performance values. For example, sensor settings can be easily saved and duplicated for other applications thanks to the IO-Link interface. This simplifies initial start-up and saves time. Condition monitoring permits predictive maintenance. Should replacement become necessary, the sensor’s configuration is automatically transferred to the new device by means of the data storage function. Beyond this, clear-cut visualization provided by standard wTeach2 software makes it possible to match the sensors precisely to complex applications. Switching thresholds and functional reserve are rendered visible, thus permitting a qualitative assessment.

PNG//smart = Photoelectronic Perfection
The sensors work with laser, red or blue light, and offer outstanding optical characteristics as well. They’re adjusted at the factory such that each sensor has the same switching distance when the settings are identical (potentiometer/IO-Link). Thanks to the balanced spot with aligned optical axis, no subsequent realignment of the spot is required. This simplifies initial start-up as well as replacement. And the sensors don’t influence each other when they’re mounted directly next to or opposite each other. Furthermore, they’re insensitive to interfering light and are consistently available in laser class 1.

First Representative of the New Generation: The 1K Miniature Design
The first group of the new product range is based on the 1K miniature design. All five functional principles (reflex sensor with or without background suppression, retro-reflex sensor with or without clear glass recognition and through-beam sensor) are available in one of the world’s smallest housing formats, namely 32 x 16 x 12 mm. Sensors with 1K housing can be connected either via plug connector, pigtail or cable, and can be configured by means of potentiometer, or via teach-in with the high-end variant. Thanks to a minimal weight of just 4 grams, they’re also very well suited for applications on robot arms. IP67/IP68 protection, LEDs which are visible all the way around and an extended temperature range of -40 to +60° C round out the portfolio.

Highlights of the PNG//smart series at a glance:
• All sensors consistently equipped with IO-Link 1.1
• Condition monitoring
• Data storage, high-end variants
• Balanced switching point and spot
• No reciprocal influence
• Highly insensitive to extraneous light
• All laser sensors also in laser class 1
• Diverse measuring tasks
• wTeach2 software
