Position Feedback

The Bettis Q-Series actuator (1) has a patented, contact-less position sensing system.
This system consists of a position probe (2) which is rides on a special curve (4) in the
pinion bottom.
The curve is shaped in such a way that the position probe moves linearly and proportionally
to the rotation of the actuator pinion.
The linear movement of the position probe is used, inside the control module (3) to
operated the limit switches.
Do not put the Control module in direct contact with magnetic material. This can cause
damage or malfunction of the position feedback.
