Three-Position Actuators

Rotomation's 3-position actuators provide an additional intermediate position, also known as reference position (RP) using internal stops that can be reached in any sequence. They share the same footprint of our standard dual rack rotary (2-position) actuators, but provide the output torque equivalent to our single rack rotary actuators. Specific characteristics and features of each series:
