■ 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)

EE-SA105 Photomicrosensor (Actuator)
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.
