IA73BHLW is a modified version of A73BHLW standard size servo, providing access to feedback potentiometer through the additional fourth orange wire, which is capable to measure the output angle directly.
40KG high torque and metal gear chain design for heavy duty application. Simply hookup the analog feedback wire to any Analog pin of Microcontroller. With this position feedback function, you can ensure the servo has reached its designated position or detect any potential impediments, of course, this allows additional closed-loop control from your controller. Enable for more complex robotics or industry applications, such as determining when the servo has reached its target, detecting when the output is blocked, or implementing your own higher-level closed-loop position control.
