PQ12-R Micro Linear Servo

PQ12-R Micro Linear Servo

The PQ12-R series of linear servos are the smallest affordable linear servo on the market today. Small enough to fit inside a tic tac box, it's very powerful with a maximum force of over 11lbs. It operates as a direct plug-and-play replacement for standard rotary servos, using the same standard 3 wire connector. Regardless of how you drive your servos, be it with an RC receiver, an Arduino board, or a VEX micro-controller, the PQ12-R servo will function in place of a regular servo, but with the added benefit of providing linear motion. They're available in a 20mm stroke coupled with gear ratio options of 30:1, 63:1 and 100:1 cover a large variety of applications. Our PQ12 is popular used in a variety of robotics applications, medical devices, radio control and 3D printable bionic hands. Our PQ12 is proudly designed in Canada by our in-house team of engineers and thoroughly tested before leaving our facility.
