The M-GAGE S18M vehicle detection sensor uses magnetoresistive-based passive sensing technology to detect 3-dimensional changes in the earth’s magnetic field when the presence of a large metal object such as a vehicle is introduced.
Applications include detection of a tractor trailer or a rail car at a loading dock, for example, or a forklift passing through an automatic overhead door. Unlike traditional inductive loop sensing technologies, the M-GAGE S18M has no external controller and installs easily above or below grade. Set-up is through simple push-button programming commands entered directly on the sensor or via a portable programming box when the sensor is mounted underground or is otherwise inaccessible. The M-GAGE S18M is constructed of a durable ABS/polycarbonate blend molded housing and operates in temperatures from –400 C to +700 C. Pricing starts at $209.
