Sensor module for brake system

A sensor module for a brake system that measures a moving distance of a movable member interlocking according to a pedal effort of a brake pedal, the sensor module comprising:

• a magnet provided on the movable member;
• a mounting block provided so that the movable member moves forward and backward, the mounting block coupled to a hydraulic block in which a master cylinder is formed to be fixed to a dashboard of a vehicle;
• and
• a detecting member provided on the mounting block in order to be spaced apart from the magnet at a predetermined interval, and configured to detect a change in magnetic field according to a movement of the movable member,
• wherein:
• the mounting block and the hydraulic block are formed as separate components and are assembled to each other,
• the detecting member has a predetermined length, and is disposed in the sensor mounting hole formed in the mounting block to have a direction parallel to a moving direction of the movable member,
• the detecting member is provided to be variable in a position thereof in the longitudinal direction of the sensor mounting hole, and
• the detecting member comprises:
• a sensor housing provided slidably in the sensor mounting hole and provided with a sensing unit for detecting a change in magnetic field,
• a connection port coupled to the electronic control unit,
• a cap bolt coupled to move together with the sensor housing and screw-coupled into the sensor mounting hole, and
• a cable connecting the sensing unit and the connection port.
