Mechanical Characteristics
Actuator operation (IF = 20 mA, VCE = 5 V) (see note 1)
Free position (FP): 14.2±0.3 mm
Operating position (OP): 13.0 mm min.
Total travel position (TTP): 12.1 mm max.
Operating force (see note 2) 0.15 N (15 gf) max.
Mechanical life expectancy 500,000 operations min. (The actuator traveling from its FP to FP via TTP is regarded as one operation.)
Note: 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.
Note: All units are in millimeters unless otherwise indicated.
