Indexing Actuators provide unidirectional rotation in fixed precise steps to hard stops. Indexers also prevent backward rotation and feature no accumulating error. All Rotomation indexing actuators feature black-anodized aluminum bodies, precision-ground carbon steel shafts, ball bearings, and stainless steel hardware.
Common Options: preloaded shaft notch, various shafts types, two rotation directions, bumper on reset stroke, integrated flow control or cushion valve, magnetic switches for actuator state feedback, high-temperature and/or oil-service seals, mount plates, extended pawl shaft for alternate state feedback (use with flag and proximity sensor), accurate keyway reference point location, and various port locations.
Standard rotation angles: 12° (30 steps/rev.), 15° (24 steps/rev.), 18° (20 steps/rev.), 22.5° (16 steps/rev.), 30° (12 steps/rev.), 36° (10 steps/rev.), 45° (8 steps/rev.), 60° (6 steps/rev.), 72° (5 steps/rev.), 90° (4 steps/rev.), 120° (3 steps/rev.), 180° (2 steps/rev.), and 360° (1 step/rev.). Combination of angles also possible as long as they add up to 360 degrees total.
