BFT PHOBOS AC A50 Swing Gate Motor

Yes — the BFT PHOBOS AC A50’s 129° maximum opening angle is the widest of any motor in the POWERgate Abu Dhabi swing gate range, across all brands and mechanism types. For comparison: the KUSTOS BT B40 reaches 126° (widest linear for 4m), the IGEA BT and IGEA KIT articulated arm motors reach 125°, the KUSTOS BT A40 reaches 126°, and the PHOBOS AC A25 reaches 120°. The A50’s 460mm rod stroke drives the gate leaf through this wide arc from the standard bracket positions. For Abu Dhabi villa gates that open inward along a boundary wall — where the gate must swing almost flat to allow full vehicle width — the 129° capability is a practical specification that no other motor in the range can match.

Both the PHOBOS AC A50 and BENINCA BOB50M handle gate leaves up to 5.0 metres, but through completely different mechanisms. The PHOBOS AC A50 uses an irreversible electromechanical linear rod actuator at 230V/210W with a 460mm stroke, electronic clutch, work-time limits, and semi-intensive duty. The BOB50M uses a 230V ball screw mechanism at higher current draw with a 455mm stroke, adjustable mechanical stops, and 30% duty cycle. The PHOBOS A50 opens to 129° versus the BOB50M’s unspecified angle. The BOB50M delivers 3500N of thrust (specified); the PHOBOS A50 specifies 500 kg weight capacity. The BOB50M uses HEADY or BRAINY control units; the PHOBOS A50 uses RIGEL 6 or ALENA SW2. For installations already using BFT infrastructure, the PHOBOS A50 integrates more naturally.

The PHOBOS AC A50 uses the same principle as the A25: a worm gear mechanism converting motor rotation into linear rod movement via the 460mm actuator stroke. The longer rod acts as a mechanical lever — the further the bracket is from the gate hinge, the less force is required to move the gate leaf. At 460mm stroke, the lever arm is long enough that even a 500 kg gate at 5.0m can be driven with 210W. This is the same power used by the PHOBOS A25 for a 400 kg gate at 2.5m — the mechanical geometry of the longer stroke compensates for the heavier and longer leaf. Correct bracket positioning during installation is critical: a bracket placed too close to the hinge reduces the lever advantage and forces the motor beyond its rated capacity.

The PHOBOS AC A50 shares the same IPX4 protection rating as the A25 — the X indicates solid particle protection has not been formally rated, and 4 confirms water splash protection from any direction. This is the same rating across the PHOBOS range and reflects the manufacturer’s choice not to certify dust ingress testing, rather than the absence of dust protection in practice. For Abu Dhabi outdoor installations, the PHOBOS AC A50 should be mounted on gate pillars that provide natural shelter from concentrated dust accumulation — particularly important given its larger 460mm exposed rod stroke compared to shorter stroke motors. Direct irrigation spray onto the motor housing should be avoided. In standard villa driveway pillar positions with reasonable cover, IPX4 is adequate for reliable year-round performance.

The BFT PHOBOS AC A50 carries a 24-month manufacturer warranty from purchase covering material and workmanship defects. For a motor with a 460mm stroke handling 500 kg at 5.0m, bracket geometry is the most critical warranty factor — a bracket positioned at incorrect distance from the gate hinge reduces mechanical advantage and forces the electronic clutch to trigger repeatedly on startup, causing cumulative stress on the rod and actuator housing. RIGEL 6 work-time limit miscalibration allowing the motor to overrun its 129° stop is a second common risk. The IPX4 rating requires sheltered pillar mounting away from direct dust and water spray.
