CEATEC2013-06 e A4 (210mm×297mm)
Position Sensor
CEATEC2013-06
Sensor allows detection of distance and angle even in severe environments
This sensor makes it possible to track travel distance and angle of a target object. As it utilizes the
orientation of a magnetic field, highly accurate position determination can be realized.
Features
• Accurate measurement over a range of several tens of millimeters
• Can be used in water, oil, or noisy environments.
• Customization is also possible.
Major Applications
• Travel distance measurement for a moveable object
• Angle detection for a rotating object
