Sensor class and detection principle
The XS218B4NAM12: This is a tubular inductive proximity sensor — the sub-category tells you it detects ferrous and non-ferrous metal targets without physical contact, using an oscillating electromagnetic field that collapses when a conductive target enters the sensing zone. The M18 barrel form factor is a standard industrial footprint that fits common mounting brackets and through-hole panel mounts, which means the mechanical integration into an existing machine guard or conveyor frame is straightforward provided the mounting hole pattern matches.
Procurement traceability identifiers
The UPC 12-digit code 389119037122 provides an additional cross-reference for inventory matching and purchase order verification, useful when the part number alone is ambiguous across supplier systems. The product description confirms this is a Telemecanique-branded unit from Schneider Electric, which carries the manufacturer's standard warranty and compliance documentation for industrial control equipment.
