The inductive sensor AI401 is a high-quality inductive proximity sensor with IO-Link which was manufactured according to the German quality standard. It is a flush mountable sensor, design M12, with a metal thread. The range of functions of the sensor is expanded significantly by IO-Link. The switching sensor can be parametrised as an NO/NC, PNP-/NPN-switching and as a measuring system with variably adjustable switching output. This reduces the wide range of versions and storage costs.

The AI401 can measure the smallest changes in distance with very great precision and output the measured value via IO-Link. IO-Link also allows the definition of limit values; if they are exceeded or drop below the minimum, the sensor outputs a warning signal. The extensive range of functions allows universal and permanent applicability with increased sensing range and good temperature stability. Even in harsh environmental conditions the sensor functions reliably thanks to the large temperature range of -40 to 85°C and the high protection ratings of IP66, IP68 and IP69K.

If you have questions regarding the IO-Link parameterization or want to use the parameterization service of autosen, please do not hesitate to contact us. Or start directly with the IO-Link starter kit ADS01.
