Magnetic Sensors

Digital-output magnetic sensors that are switched on and off by sensing the magnetic flux density of a permanent magnet. The magnetic sensors available in two versions: the highly sensitive TCS10/11 Series and the standard TCS20 Series. These devices are ideal for open/close sensing for a variety of applications, such as Cell phones, NotePCs, DSC and DVC cameras.


Ideal for applications with open/close contacts.
  • Senses the magnetic flux density in the vertical field.
  • Provides a digital output.
  • Senses the South pole, North pole or Both poles.
