Heavy-Duty Magnetic Floor Contact / GAP 75 mm (3 in) / 55 cm Shielded Cable / L-Shaped Mounting Plate / 12 VDC

SFIRE · SF-3012 · Magnetic Contact

The sentinel of the floor.

Heavy-duty magnetic contact for metal roll-up doors and industrial doors. 75 mm gap, shielded cable, and L-bracket for direct mounting.

DURABILITY

Floor, traffic, dust, moisture.

The SF-3012 lives where other sensors fail. Designed for direct floor installation in heavy-duty environments: it withstands the passage of vehicles, carts, and heavy traffic in industrial warehouses, storage facilities, and shops.

Its 55 cm, 22-gauge shielded cable protects the signal against electromagnetic interference and mechanical damage. No false alarms, no broken cables.

DETECTION

75 mm tolerance. No physical contact.

The 75 mm GAP allows the metal door to have natural movement without triggering false alarms. The magnetic field of the floor magnet activates the L-sensor's reed switch without physical contact between both parts.

When the door opens, the field is interrupted and the circuit opens. The alarm panel detects it instantly. Normally closed switch, operation at 12 VDC and 0.5 A.

INTEGRATION

Compatible with any panel.

The SF-3012 operates as a standard normally closed switch. It connects to the zone of any alarm panel or access control system that accepts dry contacts: Crow, Honeywell, Pima, DSC, Paradox, Hikvision. No proprietary protocols, no special configurations. Wire to the panel, assign the zone, and you're done.
