Ordinary inductive sensors respond to all metallic objects. The largest switching distance is achieved with steel. On the other hand, there are proximity sensors which respond to specific materials achieving the greatest switching distance using iron-free materials ("proximity sensors for non-ferrous metal"). Ferrous metals have a reduced effect and therefore flush-fitting installation in steel is possible. Examples • Selective proximity sensors of cylindrical M 30 design, as well as block shaped with nominal switching distances in relation to aluminium of 10 mm and 20 mm. These proximity sensors are suitable for objects made of copper, aluminium, tin, brass, bronze, zinc, silver, gold, manganese and lead. • Selective proximity sensors with switching dista...
