For a link driven swing arm type of passenger door operator, the link arm converts _______ motion into _______ motion.

In a link driven swing arm type of passenger door operator, the link arm is designed to convert rotary motion into horizontal motion. This mechanism is crucial for the operation of the door since it effectively translates the circular or rotary movement generated by the motor or actuator into the lateral movement required for the door to open and close.

Understanding this conversion process is fundamental for anyone involved in maintenance or troubleshooting of door operators, as it highlights the mechanical principles behind their operation. The smooth function of the door relies heavily on this conversion, ensuring that the door swings open and closed correctly without binding or misalignment.
