Digital-Output Magnetic Sensor

Digital-output magnetic sensors that are switched on and off by sensing the magnetic flux density of a permanent magnet. The digital-output 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 cellular phones, notebook PCs, digital cameras and digital video cameras.

Features

Ideal for applications with open/close contacts

Senses the magnetic flux density in the vertical field.
Provides a digital output.
Senses the South, North pole or both poles.
