Motorline MSMF-LOOP & MRMF-REC Wireless Vehicle Detector | Magnetometer Loop
Price range: £273.75 through £300.00 + VAT
Upgrade your automated gate, traffic barrier, or commercial entrance with the Motorline MSMF-LOOP & MRMF-REC Wireless Magnetic Vehicle Detection Kit. Engineered to replace traditional saw-cut inductive ground loops that require deep pavement trenching, this system uses an advanced wireless magnetometer to detect vehicle mass and direction without breaking up your driveway.
The in-ground MSMF-LOOP sensor is built to withstand extreme environments. It installs cleanly using a compact 127mm core drill hole at a 30mm depth, or sits surface-mounted with the optional LOOP-RMP rubber ramp. Capable of supporting up to 40 tonnes of wheel weight and featuring an IP68 submersible casing, the sensor transmits detection signals up to 50 meters wirelessly to the MRMF-REC multi-channel receiver.
-
No Trenching Required: Completely eliminates noisy concrete cutting, slurry cleanup, and underground wiring across driveways.
-
Low-Profile 127mm x 30mm Recess: Requires only a shallow 127mm diameter core drill hole at a 30mm depth for a fast, discreet, flush installation.
-
Industrial-Grade 40-Ton Capacity: Heavy-duty casing easily supports HGVs, agricultural machinery, and commercial truck traffic.
-
Directional & Mass Sensing: Distinguishes between approaching, exiting, and cross-traffic to prevent false gate activations.
Description
Traditional ground loop installations are labour-intensive, require expensive diamond saw equipment, and eventually fail when pavement settles and snaps subterranean wires. The Motorline MSMF-LOOP & MRMF-REC kit eliminates these pain points by utilizing a wireless magnetometer sensor node that measures disruptions in the Earth’s natural magnetic field created by metallic vehicle mass.
Communicating via a bi-directional 868 MHz RF wireless link up to 50 meters, the sensor communicates directly with the MRMF-REC receiver mounted inside your gate controller. Operating on continuous self-calibration, the system adjusts to temperature fluctuations and minor environmental changes, delivering reliable detection year-round.
Key Features
-
Multi-Sensor Connectivity: A single MRMF-REC receiver supports up to 8 MSMF-LOOP sensors, allowing full multi-lane entrance and exit control from a single control point.
-
Dual Power Configuration Options: Choose between an integrated Solar Panel + Rechargeable Battery setup or a High-Capacity Li-SOCl2 Long-Life Primary Battery.
-
Versatile Relay Receiver Output: The MRMF-REC receiver features two independent, fully configurable relay outputs (NO/NC or 8.2kΩ safety edges) and accepts 230V AC or 12/24V AC/DC power.
-
Submersible IP68 Protection: The MSMF-LOOP sensor is completely sealed against groundwater, heavy rain, road salt, and snow.

Trade Installation & Clearance Tip
Pro Tip: Because the MSMF-LOOP uses magnetometer technology to detect shifting metal masses, installing it too close to moving metal gates or garage doors will cause false trigger cycles.
The Professional Method: Always position the sensor recess at least 1.5 meters away from any moving automated gate leaf, barrier arm, or overhead door. When preparing the 127mm x 30mm hole, clean out all wet slurry and stone dust before applying a non-magnetic cold-pour sealant or epoxy filler to seat the sensor 1mm to 2mm below the driveway surface line.
