25 … 400mm

150 … 1300mm

 Function largely independent of surface

properties, ideal for detection of liquids,
bulk materials, transparent media, …

 Small dead zone at long scanning range
 Temperature-compensated scanning range

and measurement range

 1 PNP switching output (NPN) and 1 analog

output 0 … 10V / 4 … 20mA

 NEW – Both outputs can easily be taught

using a button

 NEW – Stable, all-metal design
 NEW – Process data and configuration via

IO-Link interface
