Fluid pressure supply apparatus

A fluid pressure supply apparatus comprising:

• a motor including a stator and a rotor;
• a motion conversion device configured to convert a rotational motion of the rotor into a linear motion;
• a piston which is connected to the motion conversion device and performs a linear motion;
• a housing which includes a cylinder, in which the piston is disposed to perform the linear motion, and a guide extending in a longitudinal direction of the cylinder and inserted into the piston and in which a fluid pressed by the piston is disposed in a space between an inner circumferential surface of the cylinder and an outer circumferential surface of the guide;
• a first magnet comprised in the piston;
• a first magnet sensor which is disposed on the guide and detects a change in a magnetic field of the first magnet according to the linear motion of the piston
• wherein the first magnet sensor is connected to a connector assembly.
