The Firgelli Technologies PQ12 Actuator 12V, Potentiometer is Firgelli Technologies’ unique line of Miniature Linear Actuators. It enables a new generation of motion-enabled product designs, with distinct capabilities combined in a device of this size. These tiny linear actuators are a superior alternative in designing your own push/pull mechanisms.
The PQ12 actuators are complete, self contained linear motion devices with position feedback for sophisticated position control capabilities, or end of stroke limit switches for simple two position automation. Driving them couldn’t be easier, simply apply a DC voltage to extend the actuator, and reverse the polarity to retract it. Several gear ratio’s and voltage options are available to give you varied speed/force configurations.
Basis of Operation
The PQ12 is designed to push or pull a load along its full stroke length. The speed of travel is determined by the load applied. (See the Load Curves). When power is removed the actuator will hold its position, unless the applied load exceeds the backdrive force. Stalling the actuator for short periods will not cause damage, however repeated stalling will shorten the life of the actuator.
The potentiometer actuators have no built in controller, but do provide an analog position feedback signal that can be input to an external controller. The PQ12 potentiometer actuators can be used as a linear servo by connecting the actuator to a microcontroller such as the CIB control board offered by Firgelli. This control board reads the position signal from the PQ12, compares it with your input control signal then commands the actuator to move via an onboard H-bridge circuit.
