The Turck Banner M-GAGE Q7M Flat-Pak sensor uses a passive sensing technology that is able to detect large ferrous objects. The sensor measures the change in the Earths natural magnetic field (the ambient magnetic field) caused by the introduction of a ferromagnetic object and offers an alternative to inductive loop systems.
Compact, Robust one-piece and self-contained sensor package replaces inductive-loop sensing technology with no external controller needed Designed to minimize the effects of temperature swings and destabilizing magnetic fields Simple sensor installation
