High-Security Perimeters: Embassies, Prisons, and Critical Sites
The FAAC C851 gearmotor is specifically designed for high-security facilities where rapid perimeter closure is vital to prevent tailgating, unauthorized intrusions, and perimeter breaches. With an adjustable operating speed running from 20 to 40 m/min (reaching up to 0.7 m/s), the operator quickly secures openings of leaves weighing up to 1,800 kg.
Perimeter gates in correctional institutions and diplomatic embassies benefit from the integrated electric brake fitted directly on the motor shaft. This brake maintains mechanical irreversibility and arrests gate inertia instantly at designated points, preventing forced manual pushback without operating the external manual release mechanism.
High-Throughput Commercial Logistics, Warehouses, and Stores
Distribution centers, freight warehouses, and large retail logistics stores experience continuous vehicular access demand throughout operational shifts. Standard residential or light-commercial gate operators overheat under non-stop cycling, but the FAAC C851 is built with a rated 100% use frequency (continuous duty cycle at 25 °C).
Powered by a 1.1 kW four-pole three-phase motor drawing up to 1,800 W, the system delivers up to 168 Nm of torque and a maximum thrust force of 3,000 N. The oil-lubricated worm screw mechanism dissipates mechanical friction effectively under continuous cycling, while thermal protection trips safely at 75 °C to prevent equipment failure during heavy service cycles.
Wide-Span Industrial Entrances and Telescopic Sliding Gates
Industrial entrances frequently require wide clearances for heavy vehicles, freight trucks, and industrial equipment. The C851 handles industrial sliding gate spans up to 20 m wide and leaf masses up to 1,800 kg, interfacing directly with Module 4 rack gearing via its factory Z28 pinion gear.
The unit is also engineered for telescopic sliding gate configurations where fast motion is required to coordinate multi-leaf closures. The incorporated FAAC E850S control board features an integrated frequency inverter that regulates opening and closing velocities independently. Position control is calibrated through two integrated mechanical deceleration limit switches with fine-adjustment screws and dual external magnetic limit switches mounted on a stainless steel plate along the rack.
Commercial Malls and Outdoor Traffic Enclosures
Shopping malls, commercial fleet yards, and parking hubs require outdoor automation that withstands aggressive atmospheric exposure and temperature extremes. Rated at IP54 ingress protection, the FAAC C851 operates reliably in ambient temperatures ranging between -20 °C and +55 °C.
Structural durability is supported by a 1.5 mm steel outer protective cover treated with zinc primer and powder coating, mounted on a galvanised steel operator base with 5 anchor points. For maintenance inspections, the internal E850S control unit features transparent and dark protective covers, enabling technical adjustments via programming pushbuttons and display without requiring full operator teardown.
