The Actuonix PQ12 Actuator 20mm, 30:1, 12V, Limit Switches is Actuonix's unique line of Miniature Linear Actuators. It 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 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 -S actuators have limit switches that will turn off power to the motor when it reaches within 1mm of the end of stroke. Internal diodes allow the actuator to reverse away from the limit switch. The limit switches cannot be moved. While voltage is applied to the motor power pins (2 & 3) the actuator extends. Reverse the polarity and the actuator retracts. This can be accomplished manually with a DPDT switch or relay, or using an H-Bridge circuit. The -S model cannot be used with the CIB control board.
