The Actuonix PQ12-100-6-R is a micro linear actuator with a servo-compatible PWM interface. Weighing just 22 grams with a 20mm stroke, it delivers up to 50N (~5 kg) of force thanks to its 100:1 gear ratio — making it one of the most powerful actuators of its size.

The PQ12-R series operates as a direct drop-in replacement for standard rotary servos, using the same 3-wire connector (ground, power, control). Whether driven by an RC receiver, Arduino, or other microcontroller, the PQ12-R provides linear motion where a rotary servo would normally go.
