Around the globe, automation would not be the same without non-contact inductive proximity sensors. For decades, millions of such metal-detecting devices have been monitoring presence, measuring movement and position of machine parts, valves and gears. Reliably. Day in and day out. Even in high-speed applications, exposed to the toughest industrial conditions, inductive proximity sensors safely detect steel targets as well as non-ferrous metal targets. The sensors provide feedback with precise switching points and extremely high repeat accuracy.The range of inductive 3-wire sensors consists of two basic designs: Sensors with digital output providing accurate on/off information Sensors with analog output providing absolute distance information Both technologies are available in a wide range of housing styles ranging from subminiature to standard size enclosures.
