With Brake (Model: B)
The moveable part will be retained when there is a power cutoff or the servo gets off.
It is a retainer feature to prevent an attached object from being damaged by a slider or rod being dropped when the power is turned off or the servo is turned off when an actuator is installed vertically. It is also a retainer feature to prevent an attached object from being damaged by an output axis being rotated unexpectedly with its own weight when the power is turned off or the servo is turned off when a rotary type is installed in horizontally oriented wall mount.
