The SICK ATM60-A4A12X12 is a compact rectangular inductive proximity sensor designed for non-contact detection of metallic objects in space-constrained industrial applications. Operating on electromagnetic induction principles, it reliably detects ferrous and non-ferrous metals with a nominal sensing range of 4 mm. Its flush-mountable plastic housing, IP67 protection, and PNP output make it suitable for harsh environments such as automation, assembly lines, and material handling systems.
