Optical Sensor Range Expanded with 1N and 1P Housing Formats

Wenglor’s PNG/smart generation of photoelectronic sensors is distinguished by a combination of performance and communication. An aligned optical axis and a balanced switching point, as well as large switching distances and consistent integration of IO-Link 1.1, result in a new class of sensors in extra housing formats 1P (50 x 50 x 20 mm) and 1N (75 x 32.5 x 18 mm). In addition, the product range – including high-performance distance sensors and reflex light barriers – is supplemented with two new functional principles.

Wenglor claims that the PNG/Smart sensors are currently the most comprehensive range of industry 4.0 sensors available on the market. With three housing formats (1K, 1N and IP) as well as seven functional principles and a selection of three light sources (red and blue LED light and red laser light), nearly any application for contactless object detection can be implemented. This means that not only are automated product changeovers for flexible production all the way down to lot size 1 made possible, predictive maintenance for increased systems availability and automated configuration of sensor parameters with plug & play can also be implemented.

As all sensors are equipped with IO-Link 1.1 integration into existing control systems via PROFINET and EtherNet/IP is available. A special NFC interface allows users sensor set-up via near field communication. Settings can also be adjusted using a potentiometer, teach-in or at the LED display.

Whereas the reflex sensors with background suppression and 1N housing format have an upper range of 1200 mm, the through-beam sensor detect objects at distances up to 60 m. The through-beam sensors with 1P housing have a range of up to 2 m.

The multifunction sensors can be used either as switching or measuring devices and due to WinTec technology, they do not interfere with each other. The series is rounded out by diverse connection functions: optionally connectable via M8x1 or M12x1 plug, or with cable to permit all sensors to be integrated into any system.
