Mechanical Characteristics

*1. Free position (FP): The distance between the bottom of the housing to the top of the actuator without any external force imposed on the actuator.Operating position (OP): The distance between the bottom of the housing to the top of the actuator when the actuator is pressed and the IL becomes ILEAK or less.Total travel position (TTP): The distance between the bottom of the housing to the top of the actuator when the actuator is fully pressed.

*2. Operating force: The force required to press the actuator from its FP to OP.
