Beside the normal hobby servo, a special servo which can provide feedback could be more attractive. IA81BHLW is a modified version of A81BHLW standard size servo, providing access to feedback potentiometer through the additional fourth orange wire.

50KG steel gear chain design for heavy duty application. With this position feedback function, you can ensure the servo has reached its designated position, 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.

Beside this IA81BHLW servo, we also have IA73BHLW, IB53BHU feedback servo with different feedback for selection. Custom spec is acceptable.
