The disclosure relates to a linear actuator including a base, a linear motor, a load cell and a rotary motor. The linear motor is disposed on the base and includes a fixed coil module and a movable magnetic backplane. The fixed coil module is fixed on the base, and the movable magnetic backplane is configured to slide relative to the fixed coil module along a first direction. The rotary motor is rotated around a central axis in parallel with the first direction. The load cell has two opposite sides parallel to the first direction, respectively. The movable magnetic backplane of the linear motor and the rotary motor are connected to the two opposite sides of the load cell, respectively. The load cell is subjected to a force applied thereto by the rotary motor and parallel to the first direction, and configured to convert the force into an electrical signal.

An optical reflective component and an optical encoder using the same are disclosed. The optical reflective component includes a main body, an optical pattern, a first attaching portion and a second attaching portion. The main body has a first central axis and a reflective surface perpendicular to each other. The optical pattern is disposed on the reflective surface and centered at the central axis. The first attaching portion is centered at the first central axis of the main body and extends from the man body in a direction parallel to the first central axis. The first attaching portion has an inner wall. The second attaching portion has a plane perpendicular to the first central axis. The plane is connected to the inner wall. The main body, the first attaching portion and the second attaching portion are formed of a metal material and are integrally formed with the optical pattern.
