Series Information

Typical inductive sensors

Inductive sensor

Due to their functional principle, inductive sensors are exclusively suitable for detecting metal objects. But they do this extremely reliably and are also very robust and resistant (e.g. regarding environmental factors such as high pressure or contamination), which makes them interesting for numerous industrial applications. They are mainly used wherever the detection of uniform movements is involved – for example as proximity switches for determining the position of moving machine parts such as saddles or hydraulic cylinders, for measuring rotary speeds on vehicle crankshafts, or as pulse generators for motor ignition.

Inductive sensor Main features:

  • Reliable detection of metallic objects
  • Product versions for standard or increased switching distances
  • Robust housing variants in metal, plastic or completely made of stainless steel
  • Different designs for flush, quasi-flush and non-flush mounting
  • Variants with IO-Link 1.1 or analog output - IO-Link sensors can be operated in IO-Link mode or standard I/O mode
