Overview
The ifm Electronic IGT202 is a compact inductive proximity sensor designed for non-contact metal detection in industrial automation. Engineered with durable stainless steel (316L) housing and a PEEK polyether ether ketone active face, the IGT202 delivers reliable sensing performance in harsh and hygienic environments. The M18 x 1 threaded design enables straightforward panel mounting, while dual operational modes (3-wire DC PNP or 2-wire DC PNP/NPN) provide flexible integration into control systems.
