An analog output reads out measured values as a corresponding voltage (0 to 10 V) or current (4 to 20 mA). Amongst other tasks, the sensors can be used for web edge control, height and position monitoring, and for detecting and measuring objects and contours. They can be set up quickly and intuitively with the help of a menu-driven OLED display directly at the housing, without additional software or external programming devices. Interrupted beams are displayed as a bar graph diagram at the display on the housing, which simplifies initial start-up and alignment of the light curtain, as well as quick error diagnosis. The light curtains for measuring tasks are available in two mechanical designs: “All-Around Light Curtains” are equipped with an end-cap that lights up as a switching status indicator which is highly visible all the way around. Switching status is immediately apparent, and diagnosis is possible without delay. With a beam clearance of 30 mm and measuring field heights of 150 to 1800 mm, they provide for a range of 3000 mm. In contrast, “High Resolution Light Curtains” with measuring field heights of 50 to 200 mm and a beam clearance of 2 mm are capable of detecting extremely small and low-profile objects at ranges of up to 2000 mm. With two digital switching outputs and an integrated analog output, objects aren’t just checked for presence, their dimensions are ascertained as well. Output data are made available via an IO-Link interface.
