Linear Stroke Actuator
The actuator is not provided with and does not require any limit switches, but is
electronically protected against overload. The anti-rotation strap supplied with the
actuator will prevent lateral movement.
The AHB(X)... series provides 4, 8, or 12 inches of linear stroke. The stroke of the gear
rack can be adjusted on both sides in increments of 0.8 in [20 mm] by means of the
mechanical end stops.
When reaching the damper or actuator end position, the actuator automatically stops.
The gears can be manually disengaged with a button on the actuator cover.
The AHB(X)24-3… actuators use a sensorless brushless DC motor, which is controlled
by an Application Specific Integrated Circuit (ASIC). The ASIC monitors and controls the
actuator’s rotation and provides a digital rotation sensing (DRS) function to prevent
damage to the actuator in a stall condition. Power consumption is reduced in holding
