Actuonix Micro Linear Actuator, 20mm, 6V dc, 28mm/s

Miniature Linear Motion Series · PQ12 Actuonix Motion Devices unique line of Miniature Linear Actuators enables a new generation of motion-enabled product designs, with capabilities that have never before been combined in a device of this size. These tiny linear actuators are a superior alternative to designing your own push/pull mechanisms. Their low cost and easy availability make them attractive to hobbyists and OEM designers alike.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 ratios and voltage options are available to give you varied speed/force configurations.
