These 30mm DC-powered (10-30V) inductive proximity sensors detect the presence of ferrous metal objects at extended sensing distances (up to 22mm); other metals may reduce detection range. These larger-sized threaded-barrel sensors are available in ratings up to IP69K, and with 2m pigtail cable or quick-disconnect.
