The SICK ATM60-A1A12X12 is an ultra-compact rectangular inductive proximity sensor designed for short-range non-contact detection of metallic objects in space-constrained industrial applications. With a 1 mm nominal sensing distance and flush-mountable design, it reliably detects ferrous and non-ferrous metals while ignoring surrounding metal backgrounds. Its PNP output, IP67-rated housing, and robust construction make it ideal for harsh environments such as automation, assembly lines, and material handling systems.
