BFT KUSTOS BT A40 Swing Gate Motor

The BFT KUSTOS BT A40’s ability to handle 500 kg gate leaves at just 40W comes from the efficiency of its 24V DC motor paired with a precision worm gear drive. The worm gear provides a high mechanical reduction ratio — converting the motor’s high-speed low-torque rotation into low-speed high-force linear rod movement. This mechanical advantage multiplies the effective force far beyond what the electrical wattage alone suggests. The THALIA control board also manages progressive power delivery through D-Track, applying only the torque needed at each point in the gate’s arc rather than running at full power throughout. Compare this to the BFT ATHOS AC A40 which uses 280W of 230V power for a similar 4m gate leaf at 400 kg — the KUSTOS BT A40 moves a heavier gate consuming 85% less electricity.

Yes — the BFT KUSTOS BT A40’s 126° maximum opening angle is the widest of any linear rod swing gate motor in our range. For reference: the ATHOS AC A40 and A25 reach 110°, the KUSTOS BT A25 reaches 118°, and the BFT ELI 250 N BT and ELI BT A40 underground motors reach 120°. (The IGEA BT and IGEA KIT articulated arm motors reach 125°, but they use a different mechanism.) The 126° arc on the A40 is achieved because the longer 355mm rod stroke pushes the gate leaf further through its arc than the shorter strokes on smaller motors. For Abu Dhabi driveways where vehicles require the gate leaf to open nearly flat against the pillar wall, the A40’s 126° is a practical advantage.

Both handle 4.0m gate leaves but differ significantly in technology and performance. The KUSTOS BT A40 uses a 24V motor at 40W with D-Track, magnetic limits, and 126° opening via the THALIA board, while the ATHOS AC A40 uses a 230V motor at 280W with electronic clutch, work-time limits, and 110° opening via the ALENA SW2. The KUSTOS BT A40 also handles 500 kg per leaf — 100 kg more than the ATHOS AC A40’s 400 kg rating. For very heavy 4m gates, the KUSTOS BT A40 has both the superior weight rating and the wider opening angle. The ATHOS AC A40 has the advantage of a direct 230V AC motor if the site already has 230V wiring to the gate motors and no step-down transformer is preferred.

The BFT KUSTOS BT A40 kit includes 2 x BFT Mitto B RCB transmitters — BFT’s rolling code bidirectional remote controls. The Mitto B is a single-channel variant in black housing, while the KUSTOS BT A25 kit includes the MITTO2 B RCB (2-channel variant). The RCB (Rolling Code Bidirectional) designation is the same across both — the remote sends a rolling code command and receives confirmation from the THALIA control board that the gate has responded. For the KUSTOS BT A40’s larger 4m gate leaves, operating at the boundary of radio range is common in wider Abu Dhabi driveways, and the RCB bidirectional confirmation provides reassurance that the gate command was received before driving past the gate.

The BFT KUSTOS BT A40 carries a 24-month manufacturer warranty from purchase covering material and workmanship defects under normal operating conditions. For a 24V motor handling 500 kg gate leaves on a 355mm stroke, the magnetic limit switch calibration is especially important — if the switch triggers even slightly late, the full 500 kg gate mass impacts the mechanical stop at operating speed, potentially damaging the rod, bracket, or gate hinge. D-Track force miscalibration causing repeated reversals on a heavy gate is also a warranty-voiding stress pattern. The IP44 rating requires a sheltered installation position, away from direct irrigation water spray or concentrated dust.
