*3 position actuator is dimensionally interchangable with 2 position.
4-Position Rotary Actuator
R° = Rotation of base unit in degrees (Positions 1 and 4)
S° = Change in rotation of base unit (Position 2)
T° = Change in rotation of base unit (Position 3)
5-Position Rotary Actuator
R° = Rotation of base unit in degrees (Positions 1 & 5)
S° = Change in rotation of base unit (Position 2)
T° = Change in rotation of base unit (Position 3)
Z° = Change in rotation of base unit (Position 4)
