Sensor device

A sensor device comprising:

• a rotor;
• a stator disposed to correspond to the rotor;
• a first shield and a second shield disposed on one side of the stator;
• a first collector and a second collector disposed between the first shield and the second shield;
• a Hall sensor disposed between the first collector and the second collector;
• and
• a first housing and a second housing disposed on outer sides of the first collector and the second collector,
• wherein the first housing includes a first guide protruding from an outer surface of the first housing and forming an accommodation space for the second shield on an inside thereof, and
• wherein the second housing includes a second guide protruding from an outer surface of the second housing and forming an accommodation space for the first shield on an inside thereof.

A sensor device comprising:

• a stator;
• a rotor rotatably disposed inside the stator and including a magnet;
• a Hall sensor configured to detect a change in a magnetic field between the rotor and the stator;
• a collector arranged to face each other with the stator interposed on one side and the Hall sensor interposed on the other side;
• a shield provided to surround the collector to protect the collectors from external magnetic fields;
• and
• a housing to which the shield is fixed,
• wherein the housing includes:
• a guide configured to restrict horizontal movement of a portion of the shield so that the portion of the shield is aligned with one side of the collector;
• and
• a cover configured to restrict vertical movement of a portion of the shield.
