Gear ratio: 150:1. Stroke: 50mm. Max Speed no load: 8mm/s. Input voltage: 0-15 VDC Rated at 12VDC. Stall current: 650mA @ 12V. Comes with Potentiometer Feedback. Actuonix's 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 linear actuators are a superior alternative to designing your own push/pull mechanisms. The L16 actuators are complete self-contained linear motion devices with position feedback for sophisticated position control capabilities. Simply apply a DC voltage to extend the actuator and reverse the polarity to retract it. The L16 is designed to push or pull a load along its full stroke length.
