Output monitors rotation mechanisms
Minute angle detection helps users to precisely achieve subtleness and smoothness in device operation.
Alps Electric has developed the HGAR highly reliable magnetic sensor analogue linear output for angle detection of internal device rotation mechanisms Demand for devices able to more precisely detect even minute angle changes has increased owing to recent advancements in internal device rotation mechanisms that feature smooth, accurate movement

Angle detection is necessary in the arm and leg joints of robots, production machinery, and various paper feeding controls of copy machines.
Minute angle detection helps users to precisely achieve subtleness and smoothness in device operation.
The HGAR series is a compact (2.00 x 1.50 x 0.75mm), reliable analogue linear output magnetic sensor that detects magnetic angle rotation.
Angle detection within set products and other mechanisms is accomplished by sensor readings.
Sensors detect changes in the line of magnetic force to their upper surface when magnets positioned opposite and in parallel (south/north) rotate or move.
The HGAR series, applied with a highly reliable magnetic element, contributes to product engineering to create an angle detection system that finely distinguishes angle gradation.
In addition, through the use of noncontact sensors, output disturbance from the sliding noise of conventional resistance sensors has been eliminated.
As such, the product realises an improved and nearly straight-line output with high S/N ratio.
Furthermore, while resistance sensor systems normally comprise approximately 8-bit (256) angle resolution, the HGAR series system realises four times this measure with 10-bit (1024) angle resolution.
In addition to these features, the HGAR series has a low current consumption and, owing to the application of a noncontact sensor rather than a resistance sensor, is more resistant to decay, thereby contributing to a longer operating life.
