M-GAGE™ S18M —
Vehicle Detection Sensor
Overview
The M-GAGE S18M sensor implements a passive sensing technology to detect large
ferrous objects. The sensor measures the change in the Earth’s natural magnetic field
(the ambient magnetic field) caused by the introduction of a ferromagnetic object.
This easy-to-use sensor is extremely robust and is unaffected by dirt and moisture,
making it ideal for demanding outdoor environments. Simple programming
procedures provide flexibility for a variety of applications (see page 5).
Theory of Operation
The sensor uses three mutually perpendicular magnetoresistive transducers. Each
transducer detects magnetic field changes along one axis. By incorporating three
sensing elements, maximum sensor sensitivity is achieved.
A ferrous object will alter the local (ambient) magnetic field surrounding the object, as
shown in Figure 1. The magnitude of this magnetic field change is dependent both on
the object (its size, shape, orientation, and composition) and on the ambient magnetic
field (its strength and orientation).
During a simple programming procedure, the S18M sensor measures the ambient
magnetic field. When a large ferrous object (for example, a truck, automobile, or
rail car) alters that magnetic field, the sensor detects the magnetic field changes
(anomalies). When the degree of magnetic field change reaches the sensor’s
threshold, the sensor’s discrete outputs switch.
A. Baseline magnetic field, with slight
disturbances caused by permanent
ferrous-metal objects within or near
the sensor, then . . .
Sensor Field of View and Range
The sensor range depends on three variables:
1. The local magnetic environment (including nearby ferrous material)
2. The magnetic properties of the object to be sensed
3. Sensor settings
The S18M can detect changes in the ambient magnetic field in all directions. As with
other sensors, the range will depend on the target. The strong disturbance of a large
ferrous object decreases as distance from the sensor increases, and the magnitude
and shape of the disturbance is dependent on the object’s shape and content.
The sensor can be programmed to react to magnetic field disturbances of greater or
lesser intensity, using two adjustments: background condition and sensitivity level.
Once background condition and sensitivity level are set, and both settings are stored
in non-volatile memory, the sensor is ready to detect the target object.
WARNING . . .
The mechanical opening, braking, and reversing systems of the door will not respond in sufficient time to prevent moving
trucks, cars, or material handling vehicles, even those traveling at low speeds, from coming in contact with the door. In
addition, the detection zone of the product may fluctuate due to changes in the local magnetic environment. All vehicles should
approach doors at speeds that allow the operator to ensure the door is operating properly and in an open position. Failure to follow these
procedures may result in serious injury or death.
Appropriate Use
B. After a large steel target object is
introduced.
The sensor detects the differential
(magnetic strength and orientation)
between fields A and B. If the
differential is greater than the
sensitivity threshold, the sensor’s
outputs conduct.

M-GAGE™ S18M —
Vehicle Detection Sensor
Approved Applications
The M-GAGE sensor provides a direct replacement for inductive-loop systems, and needs no external frequency controller box.
Unique mounting solutions allow an M-GAGE sensor to be replaced easily without disrupting or re-cutting the pavement.
Car Wash Entry/Exit
The Banner M-GAGE vehicle detection sensor will reliably
detect vehicles in and around car wash bays. It will
reliably detect the presence or absence of a vehicle to
provide collision avoidance at the exit of a conveyorized
tunnel, provide an entry or exit-door trigger, or trigger an
undercarriage wash.
Overhead Door
The Banner M-GAGE sensor can be used to trigger the
opening and closing of high-traffic internal overhead doors.
Mounted in the floor, it will reliably detect forklifts or trucks
as they approach the doors. Banner’s applications engineers
are available to help determine proper sensor placement for
specific door-trigger applications.
Drive-Up Kiosk
The Banner M-GAGE sensor reliably detects vehicles at
drive-through systems or other drive-up kiosks. It will
reliably detect a vehicle to trigger personnel that a vehicle
is present, and to initiate a timing system.
Loading Dock
The Banner M-GAGE sensor provides multiple advantages
for loading docks. It will reliably detect the presence of
a vehicle as it backs into a dock, triggering a light on the
interior of the building to notify the dock attendant that a
vehicle is in position for loading/unloading. The M-GAGE
can also be used to trigger dock/ramp leveling systems.

Excess Gain
Typical Target Excess Gain Curves
Once the sensor has been securely mounted and is configured, it is ready to operate.
The following two example applications show typical responses for the M-GAGE
sensor.
Example 1 describes mounting the M-GAGE 1 meter above the ground to sense an
automobile; see Figure 5. The graph in Figure 5 shows the excess gain for a typical
car. Excess gain is a measure of the amount of “extra” signal detected by the sensor
over and above the level needed to detect the target. This example assumes a level
5 sensitivity threshold. The table at right compares the change in excess gain if the
sensitivity level changes.
If the sensitivity is at level 6, then the excess gain at a given distance would be
1.3 times larger than for a level 5 sensitivity. Conversely, if the sensitivity threshold is
level 1, then the excess gain would be one third as big as for level 5.
Example 2 (see Figure 6) illustrates a typical vehicle passing over a sensor mounted
underground. Note that excess gain is greatest when the bulk of the vehicle (the rear
axle) is positioned directly over the sensor.
