The HS-645MG is one of our favorite servos of all time. We use this servo for all types of robotic applications and industrial products. The reliability and performance that you get for under $40 is fantastic. Metal gears, dual ball bearings, seperated motor and circuit board make the HS-645MG a top choice whether your project is robotics, aircraft, cars or trucks. We offer the HS-645MG in several configurations, 90° stock rotation, 180° modified rotation, continuous rotation (potentiometer is left outside the servo case) and reverse rotation.
This servo can operate 180° when given a pulse signal ranging from 600usec to 2400usec.
